2l8 ENTOMOLOGICAL NEWS. [May, 'l2 



9 long, 3.9 to 4.4 mm.; lat, thorax 1.4 to 1.8 nun.; abdomen 2. to 

 2.3 mm. 



Head. Antenniferous tubercles absent or but slightly developed. 

 Antennae short, shorter than head and thorax taken together ; first 

 segment reaching to or slightly surpassing apex of head. Head in- 

 cluding eyes as broad as long. Eyes small and quite distant from the 

 anterior angles of the prothorax, beyond which they extend, making 

 head including eyes wider than the anterior part of pronotum. An- 

 tennal joint I shortest; 2 and 4 subequal ; 3 longer than i but shorter 

 than either 2 or 4; 4 fusiform and thickest; all sparsely, shortly pilose. 

 Rostrum reaching beyond middle coxae. 



Pronotum. Variable in proportions, thickly ^punctured with large, 

 coarse punctures and covered with long, erect hairs ; anterior margin 

 straight; posterior sinuate; humeral angles rounded, callous, prom- 

 inent ; sides sinuate. 



Scutellum, about as long as head, rather broad and rounded at the 

 tip margined by a raised border rather darker than the surface; deeply 

 punctured. Metapleurae projecting noticeably and acutely beyond the 

 abdomen in a free point directed posteriorly. 



Abdomen wider than the prothorax; connexivum showing broadly 

 beyond hemelytra, especially in the short-winged forms; hairy, espe- 

 cially at the margin. 



Hemelytra in the winged form are slightly longer than the body but 

 narrower than the abdomen. The short-winged are of varying de- 

 grees of length, in some instances not reaching the 4th, in others, the 

 6th abdominal segment, both corium and membrane being shortened in 

 varying degrees, but neither wholly absent. Membrane hyaline; corium 

 semi-transparent ; nervures with dark markings. 



Legs ; thighs dark, tibiae lighter in color. 



Described from 2 long-winged and 8 short-winged females 

 and i long-winged and 3 short-winged males. Cotypes in my 

 collection. 



In Hambleton's Key* it runs to section 5, which includes 

 forms with scutelltim broad and rounded at the tip, the species 

 being scutatus, tuberculatus and indentatiis, from all of which 

 it may at once be separated by its smaller size and the absence 

 of antenniferous tubercles. From C. panncornis Sign, it is 

 distinguished by the smaller scutellum, narrower prothorax, 

 smaller head, thicker antennae, form of genital segments and 

 absence of antenniferous tubercles.
