2. ACIIRESTOCORIS gen. nov. (a^prfffro?, n6pi$). 



This genus and the following are remarkable for the nenration of the 

 corimn of the hemelytra, where an oblique vein runs from the upper apex 

 of the central cell to the costa, in addition to the two other veins running 

 from the extremity of the cell to the membrane, and so inclosing between 

 itself and the upper of these two usual veins a large rhomboidal cell at the 

 apex of the coriuni. In the present genus the thorax is exceptionally short, 

 being no longer than, if as long as, the small head. The head is subquad- 

 rate, slightlv longer than broad, less than half as wide as the base of the 

 thorax, not much produced in front of the antennae Antenna- not preserved 

 in any of the specimens. Kyes large and rather prominent, ocelli minute, 

 circular, more than twice as near the eyes as each other, opposite the middle 

 of the posterior half of the eyes. Thorax with truncate base, the sides 

 tapering rapidlv to the narrow apex, the apical margin gently, regularly, 

 and roundly eraarginate, the whole more than twice as long as broad. 

 Scutellum verv large, triangular, broader than long. Corium of hemelytra 

 large, reaching nearly to the tip of the abdomen, which the membrane 

 appears to surpass slightlv. Membranal margin straight, verv oblique 

 Abdomen large and rather full, half as long again as broad. 



A single species is known.
