180 DESCRIPTIONS OF NEW SPECIES. 



495. E. perforata. Robusta, picea, dense sordide cinereo-pubescens, 

 prothorace latitudine breviore, apice basique constricto, lateribus ante 

 medium tuberculatis, ad medium spina valida armatis, dorso punctis 

 grossis parcis notato ; elytris punctulatis et haud profunde punctatis. 

 apice bispinosis, callis eburueis parvis valde discretis, exteriore basali 

 saspe deficiente. Long. 23 30 mm. 



Texas and Northern Mexico. I should consider this as E. stig- 

 tnatica Chevr. Col. Mex. Cent. l.,but the description states that 

 the sutural spine of the elytra is wanting, the tip being trun- 

 cate. The basal joint of the antennae in the is a little flattened 

 in front, and the llth joint is a little longer than the 10th. 



2. E. Haldemani Lee., Journ. Acad. Nat. Sci., Phila., 2d, 

 ii, 102, I have a specimen from Missouri which is almost inter- 

 mediate between the Texan specimens, and the ordinary 4-gemi- 

 nata of the Southern States, and the Mississippi valley. The ely- 

 tral spots are smaller than the specimens from Georgia, as is 

 usually the case with the Missouri specimens, but the subapical 

 protuberance on the sides of the prothorax is as strong as in any 

 Texan specimen of E. Haldemani. In all of the latter species 

 that I have seen, the sutural spine is well marked, while the outer 

 one is short, and not prominent ; the specimen in question has 

 them equal as in E. ^-geminata. The evidence is in favor of 

 combining the two forms as one species, but for the present it is 

 safer to retain them as distinct. 



496. E. ovicollis. Elongata, fusco-testacea, piceo-nebulosa, subtiliter 

 dense pubescens, prothorace latitudine lougiore, lateribus late rotuu- 

 datis, coufertina punctato, callis discoidalibus duobus denudatis, apice 

 et basi truncato haud constricto ; elytris apice intus oblique truncatis, 

 vix aut breviter spinosis, fortiter sat dense punctatis, callis eburneis 

 geminatis approximatis, basalibus parvis, mediis elongatis, internis 

 autem multo brevioribus. Long. 18 23 mm. 



Texas and Northern Mexico. The llth joint of the antennae 

 of $ is longer than the 10th ; the hind femora extend a little 

 beyond the tip of the elytra, and are not spinose at tip. The 

 front cox33 are very distinctly angulated externally, though hardly 

 more so than in the four preceding species in the synoptic table, 

 and the coxal fissure is open for a small portion of its extent. 



In one specimen the inner basal ivory spot is almost wanting ; 

 in another the outer one is so reduced as to be hardly larger than 

 the inner one.
