Oblong, latlicr narrow, parallel lateriillvj depressed above, 

 black and shining, forehead with a longitndinal median 

 impression, stria complete and biarcuate anteriorly, surface 

 somewhat coarsely and roughly \ unctured, clypeus and 

 mandililes pnnctulate ; the thorax, stria complete, surface 

 somewhat closely jtunctured except in the scutellar region ; 

 the elytra, six dorsal stria complete, fifth and sutural joining 

 at the base ; the propygidiiim with large and deep punctures, 

 rather closely set ; the pygidium with larger and deeper 

 punctures and there is an obscure median transverse ridge; 

 the prosternum, keel and lobe rather closely punctured, the 

 first marginate at the sides and base ; the mesosternum is 

 punctured on each side and the strioe are similar to those 

 figured (Ann. & Mag. Nat. Hist. xi. p. 421, 1893) for 

 jf. poliius, Lew. ; the anterior tibiae are 5-6-denticulate. 



This syiecies differs from E. politus, Lew., by being rela- 

 tively longer, less wide, and more parallel at the sides, by all 

 the dorsal stria; being complete, and by the mesosternum 

 being punctured laterally, not entirely smooth. In politus 

 also the thoracic smooth scutellar area is very much Avider.

Cornillus hinodulus, sp. n. 



Ovatus, parum convexus, niger, nitidus ; fronte leviter punctata in 

 medio canahculata, stria utrinque interrupta ; pronoto stria mar- 

 ginali integra, basi ad angulos sinuata ; elytris striis 1-3 integris, 

 4—5 obsoletis, suturali dimidiata punctis indicatis ; propygidio 

 tuberculato ; prosterno bistriato mesosternoque distincte punctu- 

 latis.

This species is similar in outline to C. tuherculatus, Lew., 

 but it differs by the frontal stria being interrupted on either 

 side and not joining posteriorly until near the base of the 

 head. The striae in both species are rather fine. The thorax, 

 the marginal stria is com))lete and sinuous at the basal angle, 

 and there is a small circular impression within the angle. In 

 tuherculatus the stria is straight at the base and theie is only 

 a trace of an impression within the angle. The elytra, striae 

 1-3 complete, with the edges crenulate and the third is 

 punctiform apically, 4-5 are indicated by small apical irre- 

 gular points, the sutural is punctiform, apical, and dimidiate ; 

 tiie pygidia are finely and rather closely putictulate ; the 

 prosternum, keel is bistriate anteriorly, stria rather short, 

 surface and that of the meso- and metasterna are distinctly 

 pnnctulate, the marginal stria of the mesosternum is inter-
