Genera and Species of Coleoptera. 11 



Phormesa denusstr. 



P. anfrustior, fusca ; capite suhri'ticiiliito ; prollioi-ace latoribus antioo 

 rotundatis, doin subparalleli.s, basi vix coiistricto, utrinquo bicostato, 

 costa intoriore postico inciirvata; elytris latoribus subparallelis. 



JLib. Malabar. 



IMiicli narrower tliaii tlio procodinn-, brown ; bead rngosely punctured, 

 with a few irregular and slightly elevated lines, so disposed as to fonn 

 a kind of network ; prothorax broadly margined, the disk with two 

 elevated lines on each side, the interior approximating anteriorly and 

 fonning a short canal, strongly incurved at the base, the exterior costa 

 entire ; elytra rather broader posteriorly, each with five costse, the in- 

 tervals broad and marked with a double row of coarse obscurely defined 

 punctures ; body beneath chestnut-bro^^^l ; legs and antenn?e yellowish 

 testaceous. Length 1^ line. 



Narrower than the other species of this genus, and easily distin- 

 guished from them by the form of the costae of the prothorax and the 

 reticulated head. 



Illestfs [Colydiidae]. 



Caput quadratum, ante oculos dilatatum. OcuU rotimdati, prominentes. 

 Antenncs articulis duobus primis incrassatis, clava triarticulata. Palpi 

 labiales articulo ultimo ovato, obtuso. Prothorax subquadratus, iiTC- 

 gulariter sulcatus, lateribus marginatis, seiTulatis. Elytra costata. 

 Pedes graciles ; tihiis anguste trigonatis, calcaratis ; tarsis brevibus. 



Near Lasconotus (subfamily SyncMtince), a genus very briefly cha- 

 racterized by Erichson. The eyes, however, are said to be entirely 

 covered by the dilated borders of the head — an unusual structure in 

 this family. Here they are more than usually prominent. In the 

 female of the species described below, the prothorax is more decidedly 

 -transverse than in the male. 



Dr. Leconte, in the * Journal of the Academy of Natural Sciences 

 of Philadelphia,' 1859, p. 282, has shortly described a Colydian 

 which he refers to this genus ; he observes that it is '' at once re- 

 cognized by its concave head and three-jointed club of the antennae," 

 but nothing is said in reference to the unusual position of the eyes. 

 It is from Punta de los Reyos in California. 



Illestm terrenus. (PL III. fig. 4.) 



/. fuscus vel rufo-fuscus, opacus ; oculis nigiis. 



J£ab. Mexico. 



Dark brown or reddish brown, opake ; head partially exserted, qua- 

 drate, finely gi-anulated; eyes round, prominent, black; antenna3 with 

 the basal joint thickened, partially covered at the base, the second also
