no baud producto ; intermediae conicae obliquae, paulo distantes, mesosterno 

 antice proruinulo breviter carinato : posticae obliquae laminis intus sensirn dila- 

 tatis : pedes mediocres, tibiis calcaribus distinctis, tarsis articulo lmo longiore, 

 2 et 3 subtus lobo membraneo, 4to lobis duobus membraneis instructis, ungui- 

 culis simplicibus. Abdomen sub-6-articulatum, articulo 6to (maris ?) apice ro- 

 tundato, retractili. 



A genus which appears to belong to the Atopidae, though very distinct from 

 those mentioned in Lacordaire's work. 



25. A. piceus, piceus nitidus, minus subtiliter cinereo-pubescens, capite 

 thoraceque punctulatis, hoc latitudine plus duplo breviore, antrorsum modice 

 angustato, lateribus rotundatis, basi late bisinuato, elytris seriatim punctatis, 

 substriatis. Long. *33. 



San Diego, California : June. I have previously neglected to describe this 

 insect from my uncertainty in regard to its position. I trust that the previous 

 description will enable it to be recognized, for although there is nothing remark- 

 able in the appearance of this dark brown, hairy narrow insect, there is hardly 

 any genus with which it may be compared. 



26. Anobium marginicolle, fuscum, subtilissime punctulatum, breviter 

 pubescens, thorace latitudine breviore, lateribus valde rotundatis fortiter mar- 

 ginatis, elytris thorace latioribus, elongatis, vix obsoletissime striatis, antennis 

 articulis 3 ultimis singulatim articulos 4 8 longitudine aequantibus : oculis 

 majusculis prominulis. Long. '21. 



Puget Sound, Mr. Davidson. Belongs to the division Dryophilus Chevr., and 

 differs from a nondescript Pennsylvanian species given me by Dr. Melsheimer, 

 by the thorax being strongly margined on the sides, by the last joints of the 

 antennas being comparatively less elongated, and by the eyes being less promi- 

 nent. 



27. Anobium quadrulum, cylindricum, piceum, pube brevi cinerea seri- 

 cans, thorace latitudine breviore, inaequali, scabro, lateribus subsinuatis valde 

 marginatis, angulis posticis subrectis, basi late rotundato, scutello densius pube- 

 scente, elytris fortiter seriatim punctatis, interstitiis subtilissime punctulatis, 

 antennis articulis 3 ultimis conjunctis praecedentes aequantibus. Long. *18. 



Puget Sound, Mr. Davidson. Allied to A. foveatum Kirby, but is less 

 elongate, with the sides of the thorax less sinuous, the posterior angles not 

 acute but subrectangular, and the base much less rounded. 



28. Anobium cornutum, nigrum, cylindrico-ovale, subtiliter punctula- 

 tum, pube brevissima cana vix conspicua vestitum, thorace latitudine duplo 

 breviore, modice convexo, lateribus praecipue ante medium rotundatis, basi late 

 rotundato, angulis posticis rectis prominulis, antennarum articulis 3 ultimis 

 conjunctis reliquos fere aequantibus. Long. "11. 



Mas, mandibulis cornu erecto tenui, capite sesqui longiore apice incurvo, 

 armatis ; femina mandibulis simplicibus. 



California. This interesting species was sent me by Mr. Andrew Murray, as 

 having been hatched in great numbers from some galls sent from California. 

 The two horns of the male meet at their incurved tips. 



Scotob^enus. 



Corpus elongatum oblongum, apterum, elytris haud connatis. Clypeus pla* 

 nus antice truncatus : labrum late rotundatum : mentum parvuni subhexagonum 

 medio subelevatum, apice liberum, fere truncatum : antennae extrorsum paulo 

 crassiores, articulo 2ndo brevi, externis 4 vel 5 rotundatis. Pedes mediocres, 

 femoribus paulo clavatis, tibiis angustis, linea interna insculptis, tarsis tibiis 

 fere duplo brevioribus, articulis subtua flavo-villoris, articulo posticorum lmo 

 paulo longiore. 



Allied to Upis, Centrionipus, Nyctibates, &c, but easily distinguished by the 

 above noted characters.
