femora rather strongly, the four posterior feebly, clavate. Length 0.9 mm. ; 

 width 0.45 mm. 



Texas (Galveston). 



The two specimens, which I took some years ago, represent a 

 species allied to fatuus and heedillus, but distinguishable from the 

 former by the shorter and more inflated elytra, smaller head with 

 larger and more prominent eyes, still more slender antennae with 

 paler club and transverse eighth joint, and from the latter by its 

 very much smaller head and larger eyes. 



18. E. callidus n. sp. — Moderately slender and ventricose, polished, 

 subimpunctate, black, the elytra very slightly paler, dark piceous ; legs and 

 antennae pale, the club of the latter dark ; pubescence nearly as in fatuus. 

 Head rather small, almost circular, convex as usual, the eyes moderate in size 

 and not prominent. Antennse rather short but slender, with the club abrupt 

 and strong, barely as long as the head and prothorax ; second joint strongly 

 obconic, not quite twice as long as wide, distinctly longer than the next two 

 and much thicker ; three to seven subequal in thickness, the fifth and seventh 

 possibly a little thicker, oval ; third, fourth and sixth equal and as long as 

 wide ; fifth much longer, % longer than wide ; seventh quadrate ; eighth 

 much wider, % wider than the seventh, very short and transverse, at least % 

 wider than long, with its apex broadly conic ; ninth abruptly fully % thicker 

 than the eighth ; ninth and tenth perfectly similar, transverse and fully % 

 wider than long ; eleventh not thicker, distinctly shorter than the two preced- 

 ing, obliquely, gradually and acutely pointed. Prothorax not quite as long as 

 wide, fully 3^4 wider than the head, in form and sculpture nearly similar to 

 the preceding species. Elytra oval, short, not more than }4 longer than wide, 

 but little more than twice as long as the prothorax and nearly % wider, 

 widest before the middle, the sides evenly and rather strongly arcuate 

 throughout the length ; humeral plica and adjacent impression strongly devel- 

 oped and conspicuous ; suture feebly beaded for some distance from the base. 

 Hind wings well developed, coarsely cellular in structure, fringed with rather 

 long erect hairs. Legs somewhat short, the femora moderately clavate. Length 

 0.85 mm. ; width 0.35 mm. 



Texas (Colorado River). 



This species is also closely allied to fatuus, but differs in 

 numerous structural characters, among which may be mentioned 

 the shorter and smaller, though rather more inflated elytra, much 

 smaller head and shorter antennse, with a much shorter and more 

 transverse eighth joint, and shorter, more equal and more trans, 

 verse ninth and tenth joints. The elytra are less basally narrowed 

 and broader at the basal margin than in fatuus. 



19. E. de1)ilis n. sp. — Moderately ventricose, polished, the elytra very 

 feebly and sparsely punctulate ; body deep black throughout, the legs dark ;
