Brues, C. T.: Some new exotic Phoridae
some new exotic phorId.e. 411 the occiput to the anterior edge of the front than high. Eyes very small, oval, their longest diameter only about one-half the diameter of the third antenna! joint. Antennae small, rounded, the finely pubescent arista reaching just beyond the tip of the thorax. Palpi large, swollen, projecting one-half the length of the head-height, bristly below. Proboscis very short, fleshy. The front is rather thickly hairy, but there seem to be no bristles except a row of three weak ones on the cheek, just below the eyes. Ocelli absent. The thorax is likewise without macrochaetae, about four times as vide as long. Abdomen with six dorsal sclerites, the first longer than the second; third, fourth and fifth subequal to the second but gradually lengthening; sixth one-half longer, the first to the fifth have a line of transparent dots along the posterior margin indicating the insertion of rows of small macrochaetae. Fifth segment without a gland opening. On the venter there is a single chitinized plate near the apex. External genitalia small. Wings and halteres entirely wanting. Legs stout, the hind tibiae each with a single very small spur. Hind metatarsus seriately setulose as usual. One female from Kibosho, German East Africa, March l'JOH (K ATONA). This is the second species of Chonocephalus to be discovered in the female sex. Of the two other known species C. dorsalis WAND, from the East Indies previously mentioned is known in both sexes, while (,'. similis BRUES from India is known only in the male sex. The discovery of a third species in Africa so very similar to the East Indian form is certainly unexpected and widely extends the range of this most remarkable wingless genus. The striking similarity to C. dorsalis consists in the presence of the six heavily cbitinized contiguous dorsal plates and one ventral one, the bare front and the general habitus of the body. The absence of anterior frontal bristles in the African species may be accidental as bristles are easily broken from alcoholic specimens. •lust how great the variation may be among species of these extremely degenerate wingless females and what may constitute valid specific characters I hardly feel competent to say in view of our limited knowledge of this group, but I think there can be no doubt of the propriety in recognizing the African and East Indian females as different in absence of the male of the new species. In kiboslioënsis the head is wider than the thorax when seen from above and the comparative lengths of the dorsal abdominal scelerites are different from in dorsalis.
