FAMILY CORIXID^:. 



396. CoRiXA STRIATA Lhm. — Length of body 3 — 3^ lines. Many 

 specimens taken with the preceding. 



Body yellowish, depressed, naked, smooth. Head inflexed, obtuse ; 

 eyes brownish, triangular ; antennae inserted before the eyes under the 

 lateral margin ; scape incrassated ; remaining joints together are setiform ; 

 prothorax subtriangular, with the hemelytra, brown, streaked transversely, 

 with irregular yellow streaks ; epipleura not streaked, pale-yellow ; breast 

 black, spotted with yellow on the sides ; legs yellow ; anterior and pos- 

 terior tarsi natatory \ the latter longer than the tibiae ; abdomen with the 

 first ventral segment, and an abbreviated basilar band of the second, 

 black. 



Variety B. With the first joint of the posterior tarsi black at the 

 tip. This may be a distinct species ; there were seven 

 specimens distinguished by a black annulet surrounding 

 the terminal half of the first dilated joint of the tarsus 

 in question. 



[284.] 397. Corixa carinata Kirby. — Length of body 4 lines. 

 Two specimens taken with preceding species. 



Body yellow underneath, embrowned at the insertion of the legs. Head 

 yellow j front broad and flat ; labrum transversely tricarinate ; occiput 

 obtusangular ; vertex with an obsolete longitudinal ridge issuing from the 

 angle of the occiput j prothorax with a longitudinal intermediate ridge, 

 transversely streaked with yellow and brownish black ; hemelytra 

 sprinkled, and towards the base almost streaked, with black and yellow. 

 In other respects this species resembles C. striata, 



398. Corixa planifrons Kirby. — Length of body 4 lines. 1 wo 

 specimens taken with the preceding. 



This species differs from the preceding in having the under side of the 

 body black, with two pale spots on each side of the breast, and the anal 

 half of the abdomen pale-yellow. The head is yellow, the vertex is ridged 

 longitudinally and separated from the front by a transverse curvilinear 

 ridge ; and from which the anterior part of the face is inflexed, plane or 

 slightly concave ; in other respects this species exhibits exactly the same 

 characters with C. carinata. They may perhaps be sexual varieties.
