COLEOPTERA 467 



This species is distinguished from E. sulcatiis by the shape of the prothorax, and 

 by the less deep furrows of the elytra. The interstices ot the latter also are flattened 

 and somewhat broad, not so ridge-like as those of E. sulcatus. Otherwise the two 

 species are much alike ; in both the light colour of the margins forms rather broad and 

 conspicuous areas at the angles of the prothorax. The pubescence is aggregated into 

 tufts on the elytra. 



The pygidium is coarsely punctuated in both sexes ; that of the male is truncate or 

 subtruncate with rounded angles, very slightly depressed at the middle of the posterior 

 margin ; that of the female somewhat broader, either rounded, or truncate with rounded 

 angles and a very slight depression in the posterior margin. The male supplementary 

 segment tapers more or less, but is rounded apically, fringed with long hairs. 



Var. diniidiatiis. In the Maui specimens this colour variety, described under 

 E. i))iprcssiis, is present in a strongly-marked form in both sexes. 132 specimens.

" Parum latus, depressus, opacus, brevissime pubescens vel setulosus, fusco-rufus ; 

 prothorace dense subrugulose punctato, disco parum distincte quadri-impresso, angulis 

 posterioribus rectis ; elytris subaequalibus, regulariter seriatim et fortiter punctatis, 

 interstitiis planis; abdomine opaco, dense subobsolete punctato. Long. ^,\, lat. if mm." 



This was originally diagnosed by me from a single specimen ot the female sex. 

 The diagnosis should be amended as regards the sculpture of the elytra, the striation of 

 which is remarkably deep, so that the punctures in the striae are indistinct ; the in- 

 terstices are narrow. This correction is of importance because of the discovery of the 

 following species, E. sculptus, which is closely allied to E. obsoletus but has the 

 punctures in the striae distinct. 



The male has the sculpture of the pygidium close and rough, in the form of 

 longitudinal subeffaced granules. 



E. obsoletjts seems to be not uncommon in Hawaii. Mr Blackburn found it in the 

 stems of ferns. We have now about 128 specimens.
