260 Mr. C. J. Gaban's additions to the 



Spalacopsis si))uUs, sp. n. 

 Fusco-ferruginea, pube fulvo-grisea haud dense pnbescens ; pro- 

 thorace dense punctato, quam basi elytrornm haiad angustiori, 

 supra lineis tribus pallidioribus ; elytris dense snblineatimque 

 pnnetatis, utrisque lateraliter unicostatis. Long. 12 mm. 



Hah. IMexico, Acapiilco in Guerrero {Tlor/e). 



Dark reddish brown, with a greyish or fulvons grej' pubescence, 

 whicli is somewhat uniformly spread and scarcely thick enough to 

 conceal the punctuation of the head and thorax, while it leaves 

 the stronger punctures of the elytra clearly visible. The elytra at 

 the base are not broader than the base of the prothorax ; they are 

 slightly constricted a short distance behind the base, and attain 

 their greatest width a little distance beyond the middle ; their 

 apices are cut away very obliquely from the suture, so that they 

 appear somewhat divergent. Each elytron has a single longi- 

 tudinal costa, disappearing in front, which is placed along the 

 angle between the dorsal and lateral face. The row of punctures 

 contiguous to this costa on the dorsal side is more conspicuous 

 than the rest. 



From S. variegata, Bates, which it somewhat resembles 

 in shape, this species may be distinguished by its much 

 more uniform coloration, and by the absence of the 

 second (dorsal) costa from the elytra. 



Spalacopsis fusca, sp. n. 

 Precedenti similis sed minor, nigro-fusca, griseo tenuissime 

 pubescens. Long. 7^ — 9 mm. 



Hah. Mexico, Acapulco in Guerrero (Hoge). 



Blackish brown, with a faint greyish pubescence. Head and 

 prothorax rather thickly punctured. Elytra distinctly punctured, 

 and having the punctures arranged in rather closelj' approximated 

 rows, with an impunctate and scarcely raised interval along the 

 dorso-lateral edge ; this subcostiform interval disappears anteriorly 

 and posteriorly. The dark colour of the elytra is lightened by a 

 faint reddish tint. 



This species differs from the preceding by its smaller 

 size, scantier pubescence, and darker coloration. The 

 prothorax is without lines of paler pubescence. The 

 impunctate interval between the dorsal and lateral face 

 of each elytron is not distinctly raised nor costiform, as 

 in S. similis.
