Washington Territory, Mr. Gibbs. The palpi and feet are destroyed : it is 

 perhaps a Phryganophilus, but in the absence of an authentic type of the genus 

 for comparison, I cannot be certain.

 versus latera insequali, confluenter foveatim punctato, linea dorsali lsevi, sulco 

 basali profundiore, elytris antice modice, postice subtiliter punctatis ad api- 

 cem truncatis bispinosis, spina interna longiore, femoribus haud spinosis, 

 antennis articulo 3io spina interna brevi, spiculoque externo obsoleto, sequen-

Umpqua Valley, Dr. Newberry. Closely resembles the female of E. s i m - 

 plicic olle Hald. (E. pulverulentum Hald.,) but is mueh larger, with the 

 sutural spine of the elytra longer than the outer one ; the thorax is less round- 

 ed, much more coarsely punctured, with the basal groove deeper ; the dorsal 

 elevation is also linear, there is an anterior oblique discoidal callus each 

 side, and the sides are quite distinctly impressed : inE. simplicicolle the 

 discoidal callus is not seen and the sides are hardly impressed. 



33. Leptura xanthogaster, elongata, nigra, opaca, capite thoraceque

 punctatis flavis nitidis parce breviter flavo-pubescentibus, macula oblonga sub- 

 humerali, altera laterali ad medium, trienteque postico nigris, abdomine pedi- 

 busque flavis, tibiis ad apioein tarsisque anterioribus infuscatis. Long. *43.

 Zee, but it differs by the absence of the subapical round yellow spot of the 

 elytra, as well as by the yellow abdomen.

 gustatis, ad apicem oblique truncatis, angulo externo acuto, sat dense puncta- 

 tis, parce breviter pubescentibus, guttis tribus ad marginem pallide flavis 

 ornatis, prima basali, secunda obliqua paulo ante medium, tertia pone medium,
