Remarks. — As a result of the reexamination of the original description of C. (Crossocerus) pseudopalmarius I arrived at the conclusion that my asiaticus must be identical with that species, altough in the description of pseudopalmarius no mention was made as to the character of the mar.dible. The difference between the two forms seems to be only in the easily changeable hue of the colour, yellow and white. rf (hitherto unknown). Length 6—6.5. mm. Colouration as in Q, but the white parts (sometimes more or less pale ferruginous) on the legs much more broadly expanded, especially on tibiae and tarsi, antennái flagella beneath narrowly ferruginous. Pubescence also similar. Differences in structure: The form of the clypeus : Fig. 39, mandible bifid at apex (as one of the subgeneric characters), the anterior tooth longer, occipital carina reaching near the hypostomial carina and suddenly terminated at the ends, but not toothed or roundly produced as in 0_

, antennái joint 1 approximately twice as long as the minimum interocular distance at base of clypeus as in 9> but joint 3 relatively shorter, 2.0—2.2 times as long as wide at apex (in 0_ about 2.5 times so), ultimate joint apically somewhat com-
