Diagnostic characters. — As I have been unable to gain a definite 

 knoAvledge of the typical form, I have given LeConte's description in 

 ftill. He states that in form granidata somewhat resembles E. qinid- 

 ricoUis., but less convex, and that the sculpturing of the elytra con- 

 sists of small, somewhat shining, flat tubercles, arranged in series, 

 Avith intervening scattered acute elevated punctures. He has also 

 described two other forms, ohti/sa. from California and aspera from 

 New Mexico, both considered by Doctor Horn as synonyms of the 

 present species. There are two specimens before me Avhich have been 

 compared with the type of ohtxsa LeConte by ]\Ir. Blanchard and 

 pronounced by him to be that form. LeConte's description is as 

 follows : 



E. ohtusa. — Elougata, nigra capite thoraceque coufertim puuctatis, hoc ovato, 

 latitudine paulo brevioi'e, lateribus rotuudatis, postice obliquis, angulis posticis 

 obtusis. spatio parvo Ijevi utrinque ad medium notato, elytris postice oblique 

 atteuuatis valde declivibus, basi truncatis bumeris obtusis, grauulis puuctisque 

 iutermixtis vix seriatim positis: femoribus auticis subtus obtuse augulatis. 

 Long. .60. 



He also writes that the elytra are punctured toward the suture, but 

 behind and at the sides the punctures are replaced by oval elevations 

 of moderate size, which are arranged in rows, though not very dis- 

 tinctly, and the humeral angles are not pi-oduced. 



The exam])les from Siskiyou County, California, do not answer 

 to the above descriptions. ]Mr. Blanchard has compared them wdth 

 the type and wi'ites as follows : " Not like the type of g/'amdata, a 

 male from Oregon, which is less rough; and obtusa (male from Cali- 

 fornia) has a more convex prothorax than granidata, more rounded 

 on the sides, ami more coarsely and densely punctate, being in these 

 particulars moi'e like your Siskiyou specimen. In granidata the disc 

 of the elytra is irregidarly pimctate and rugose ; in o/>^(/6'« more rugose 

 and less evidently punctate."" Tn another letter he writes that " Your 

 Siskiyou examine is perhaps more nearly ((spe?Yi.''' 



If aspera is a synonym of graiiulata it w-ill be surprising as found 

 in New INIexico. I shall again give a description of LeConte's in full: 



E. aspera. — Nigra, capite 1borace(|ue opacis, fortiter sat dense puuctatis, hoc 

 latitudine paulo lireviore, obovato uiodice couvexo, apice subemarginato, basi 

 paulo sinuata apica baud augustiore, lateribus teuuiter marginatis rotuudatis, 

 postice subsiuuatis. angulis posticis obtusis baud rotuudatis; elytris ovalibus, 

 thorace duplo latioribus basi emarginatis humeris subacutis, apice valde de- 

 clivibus ()bli(pie atteiuiatis, dorso deplanatis. lateribus subito iuflexis, undique 

 grauulis recliuatis nitidis breviter pilif(>ris dense suI)S('riatim positis. et ])arce 

 transversim rugosis; antennis ca;pite thoraceque vix brevioribus, extrorsum 

 paulo iucrassatis ; femoribus auticis muticis, Long. .60.
