376 SERRICOKNIA. 



Numerous examples. This insect resembles the North-American JEolus amabilis 

 (Lee.) ; but it is broader and more robust, the thorax is parallel at the sides behind, 

 with the hind angles broadly triangular, and the fourth tarsal joint is very feebly 

 excavate above. The colour is variable, according to the predominance of the light 

 or dark colour ; in some specimens the testaceous markings are partly confluent. 



3. Drasterius simiolus.

 Hob. Mexico 12 , Yautepec in Mexico, Mexico city (Edge). 



Found in plenty by Herr Hoge. The angles of the thorax are sometimes testaceous. 

 The locality " California " is also given by Candeze \ but it requires confirmation. 



4. Drasterius flavipes. 



Moderately elongate, rather broad, somewhat convex, shining ; black, the anterior and hind angles of the pro- 

 thorax and the antennae testaceous, the legs flavo-testaceous, the under surface pitchy-black ; above and 

 beneath clothed with fine yellowish-cinereous pubescence. Head convex, thickly punctured, the frontal 

 carina not prominent ; antennae with joint 3 slightly longer than 2, the two together as long as 4. Pro- 

 thorax convex, about as long as broad, narrowed in front, the sides rounded anteriorly and very feebly 

 sinuate behind ; the hind angles stout, strongly produced, not divergent, sharply carinate above, the 

 carina distant from the margin but joining it at the tip ; the surface thickly, rather coarsely punctate. 

 Scutellum convex in front. Elytra twice the length of the prothorax, narrowing from the middle, 

 rounded at the apex ; deeply punctate-striate, the punctures distinct ; the interstices feebly convex and 

 roughly punctured. Beneath coarsely, rather sparsely punctate. 



Length 6J;-6|, breadth 2-2| millim. 



Eab. Mexico, Amula in Guerrero (H. H. Smith), Mexico city {Hoge). 



Two specimens, one of which has the elytra abnormally formed. Closely allied to 

 I), simiolus, Cand. ; but differing from it in having the thorax almost parallel behind, 

 more sparsely punctured, and with the hind angles more sharply carinate, the 

 scutellum more tumid, the elytra more deeply and more coarsely punctate-striate, and 

 the under surface not so closely punctured, the legs and antennae entirely pallid. From 

 I), dugesi, Cand., it may be known by its stouter build, and by the wider, non-divergent, 

 very sharply carinate hind angles of the thorax. 



5. Drasterius dugesi. 



Drasterius dugesi, Cand. Ann. Soc. Ent. Belg. 1889, p. 99 (Elat. Nouv. iv. p. 33) \ 

 Hah. Mexico, Guanajuato 1 (Salle). 



Allied to I), simiolus, but less convex ; the hind angles of the thorax and the 

 antenna? are testaceous, the legs flavous. We have received a single specimen of this 

 species, agreeing with the type communicated by Dr. Candeze.
