case in H. Hneata ESCHSCH. In KIRKALDY ? S type tlie white longitudinal line of the hemelytra is effaced. Size and Color. Length, 11.7 mm (male allotype), 10.8 mm (male parallotype); the general color of the body is a brownish-yellow, the underside of the abdomen darker in color and with frosted appearance: a narrow white stripe extends along the median line of the body from the posterior margin of the eyes to the posterior margin of the pronotum; a frosted band along the sides of the body from the anterior margin of the pronotum to the posterior margin of the sixth abdominal segment. Structural Characteristics. H e a d : Length, 87 units; the ratio of the anteocular part of the head to the postocular part is given in the formula AO:PO: :56:24; the dorsal interocular groove is about equal in length to the diameter of an eye; the ventral interocular groove is long, extending from about fhe middle of the anteocular part of the head nearly to the pronotum, the postocular part being broader and deeper; clypeus bluntly conical and polished; the rostrum surpasses the eyes by about one-half the postocular distance; the antennal formula is: 13:29:60:34. Pronotum: Length, 45 units: an encircling row of pits parallel to the anterior margin and close to it; the posterior lobe with a median longitudinal row of pits with numerous other, pits arranged more or less in rows, each of the propleura with a marginal row of four or five pits. Metanotum : The hemelytra are large and long, extending to the posterior margin of the fourth abdominal segment on the allotype and slightly farther on the parallotype. C o x a e : The distance between the first and second coxae is to that between the second and third coxae as 27:48 (allotype); all the acetabula are pitted; the anterior and middle acetabula having two or three pits each side of the cleft; the posterior acetabula with two pits. F e m o r a : The anterior f emora do not surpass the apex of the head and the posteior femora do not surpass the tip of the abdomen. Abdomen: In dorsal view the sides of the seventh segment of the abdomen of the male are almost parallel; the ventral side of the sixth abdominal segment of the male is transversely depressed, the width of the depression being about equal to one-half the length of the segment and rather hairy as is the posterior half of the fifth
