rounded; head large, quadrate, sinuato -truncate at base, the angles 

 very distinct and narrowly rounded, the neck very slender, scarcely a 

 fourth as wide as the head, the median line deeply Impressed at and 

 anteriorly to the middle, the eyes small, rather finely faceted; antennae 

 moderate in length, thesecond joint very much longer as well as thicker 

 than the third; prothorax small, only moderately narrowed at base, 

 finely, feebly impressed along the median line throughout the length, 

 the surface not transversaly impressed before the base; side margins 

 acute, marked by larger punctures bearing stiff setae but not beaded', 

 scutellum feebly sculptured, flat; elytral humeri moderately exposed; 

 abdominal impressions impunctate; legs rather short, slender, bristling 

 throughout with sparse erect setae ; hind tarsi filiform but very short, 

 the basal joint not longer than the next two combined, two to four 

 subequal, rather short; claws well developed, somewhat strongly 

 arcuate. Florida vAnenrota 



Body only moderately small in size, much stouter, convex, not parallel, the 

 anterior parte much narrower than the hind body; middle coxae moder- 

 ately separated, the mesosternal process extending fully to the middle, 

 its tip arcuate, slightly free and separated from the correspondingly 

 sinuate apex of the shorter, transversely convex metasternal projection 

 by a very short, scarcely depressed isthmus; prosternum moderate be- 

 fore the coxae, its hind margin broadly angulate, the angle slightly 

 rounded, the corneous plates under the coxae tbioner and paler than 

 usual, their inner margins arcuate, attaining the median line posteriorly 

 but leaving a small triangle of membrane exposed anteriorly; head 

 rounded behind, convex, the median line not impressed, the neck very 

 slender, scarcely more than a fifth as wide as the head; eyes rather small, 

 but slightly prominent; antennae long, gradually and slightly Incrassate 

 distally, the second and third joints long, subequal, the subapical not 

 transverse but compactly joined, the eleventh not quite as long as the 

 two preceding combined, pointed; prothorax only moderately narrowed 

 at base, convex, acutely sulcate along the median line except at apex, 

 the sulcus ending posteriorly in a large deep fovea, which is sometimes 

 transverse, the surface also sometimes transversely impressed near the 

 basal margin; scutellum flat, acutely granulose; elytral humeri very 

 widely exposed; abdominal impressions subimpunctate; legs long, very 

 slender, the hind tarsi almost as long as the tibiae, the basal joint as 

 long as the next three combined, the latter successively decreasing in 

 length; claws slender, moderately arcuate. Pacific coast of America. 



Lissagria 



11 — Form much more slender than in Lissagria, convex, the middle coxae 

 more or less narrowly separated, the mesosternal process extending to 

 the middle, sometimes parallel- sided and very narrow but varying 

 somewhat, the apex arcuate, free and separated from the short meta- 

 sternal projection by a long, transversely and strongly convex, more or 

 less distinctly depressed isthmus ; prosternum before the coxae moder- 

 ate in extent, its hind margin on the exposed surface broadly and ob- 

 tusely angulate, the angle rounded; on the inner or subcoxal edge it is 

 ■trongly and acutely cusped at the middle ; head rounded at base, the 

 neck about a fourth as wide, the eyes moderate, not at all prominent.
