below the ocellus; lateral carinae arcuate, but not angled, reaching the corner 

 of the face. Pronotnm as in CE. trifasciata, except that at each posterior lateral 

 angle there is a minute tooth pointing downward. Elytra, when closed, pre- 

 senting an unusually flat surface on the dorsum. The metasternum appears 

 to be shorter than is usual in the other species. 



Color. — The color and markings are very much like the other species, 

 except that the middle and outer bands of the elytra are less distinct, and the 

 middle and apical spaces have a few brown dots in them. 



I have described this as a new species with much doubt, as it is quite 

 possible it is but a variety of CE. trifasciata ; but the elevated occiput, spine, 

 or tooth on the pronotum, and short metasternum would appear to separate 

 it from that species. 



Subdivision 2. — Head and thorax, especially the latter, of more than 

 usual depth, massive ; vertex broad, deflexed, more or less rugose, and often 

 somewhat tuberculate ; eyes rather small, and not prominent. Pronotum 

 short, but rather longer in proportion than in the preceding subdivision ; 

 rugose and generally more or less tuberculate ; median carina distinct and 

 slightly raised, usually distinctly notched ; lateral carin^B sub-acute on the 

 posterior lobe, and generally obliterated or sub-distinct on the. anterior lobe; 

 anterior marjxin sul)-an simulate or rounded. 



a. Of large size ; disk of the pronotum tuberculate ; lateral carinse 

 olditerated or indistinct on the front lobes by the convexity. Posterior 

 femora rather short, much compressed, very broad. Elytra marked with 

 large, fuscous spots. 



I think it very probable that some of the species included in this sub- 

 division should be transferred to Ere?nobia, Serv. (Thrinchus, Fisch.) E. 

 clavrld, Lucas (Ann. Soc. Ent. Fr., 2d ser., IX, 364, PL 8, Fig. 1), is cer- 

 tainly very closely allied in shape, size, carvings, markings, and color to the 

 western variety of OE. jj/ioBfiicoptera and to CE. discoidea.

Somewhat like the male of CE. corallipes, Hald. Vertex broad, trans- 

 verse ; the large central foveola is divided by a single or double carina, which 

 runs from the center of the front margin back two-thirds across it; when 

 double, the infolding of the margin, seen from the front, resembles a W ;
