stria rises from a punctiform impression which also gives oflF a 

 very short rudimentary basal striole. As in S. nanus, there 

 seems to be no trace of the posterior marginal seta of the prothorax, 

 which is present in aS'. punctiventris in the lateral channel just 

 beside the basal angle. I believe the genus Setalimorj)hus is 

 apterous. The discovery of S. regularis, which i^ in many ways 

 intermediate between S. prmcfiventris -And S. nanus{ = Phenaulax 

 stenomorpha Tschitscherine) indicates that, conti'ary to my 

 formerly expressed idea, Phenrndax is not entitled to recog- 

 nition as even subgenerically distinct from Setalimorphus.*

 Genus E u D a l i a , 



EUDALIA CASTELNAUI, n.Sp. 



Black, vertex and disc of prothorax nitid. Head wider than 

 prothorax(19 mm. across eyes). Prothorax hardly longer than 

 broad(l-8 X 1-75 mm.), roundly ampliate on sides, Isevigate on 

 middle of disc, punctate anteriorly and posteriorly; base truncate; 

 basal angles obtuse. Elytra wide(6 -3 x 4mm.), punctate-striate; 

 interstices shagreened, glabrous, third and fifth intei'stices with 

 a row of distant setigerous punctures. Length 10-5, breadth 

 4 mm.

This species is at once differentiated from the other large-sized 

 species of the genus by the glabrous interstices of the elytra; and 

 from U. froygatti Macl., and E. subUevis Macl., by its much larger 

 size. It is nearest E. nigra SI., but is easily distinguished from 

 that species by legs entirely black; head smoother, less setose 

 behind eyes; prothorax less setose, more convex, less ampliate on 

 sides, border less strongly developed, basal angles less marked; 

 elytra glabrous; sides of mesosternum and metasternum more 

 sparingly and less strongly punctate; second ventral segment 

 with only a few punctui'es on each side near anterior margin, etc.
