Number of speciiiiens studied, 9, 



Types in my own and Mr. Blanchard's collections. 



Type-locality. — San Diego County, California. 



Salient type-characters. — The buccal processes of the gense are pro- 

 duced and anteriorly prominent. Pronotum moderately convex; 

 apex subtruncate in circular arc; sides rather strongly rounded, con- 

 stricted at basal ninth, thence straight to the basal angles, the latter 

 subrectangular; apical angles obtuse and distinct. Elytra about a 

 third longer than wide; humeri obtuse and rounded, epipleural 

 margin just visible from above; disc coarsely punctate, punctures 

 somewhat eroded, noticeably coalescing in twos and threes, simple 

 about the suture, muricato-tuberculate laterally and about apex; the 

 most peripheral are distinct and shining tubercles. 



Diagnostic characters. — Smaller and similarly sculptured to con- 

 sohiina., to which it is closely related, and easily separated by the 

 unusually developed buccal process of the gense that are anteriorly 

 produced and somewdiat acute. 



An example before me, and kindly given me for study by Colonel 

 Casey, apparently belongs here. It has the thorax very coarsely and 

 densely punctate. There is also a tendencA' for the punctures to 

 coalesce. In fact, it is more strongly sculptured throughout than 

 any other specimen of hlanchardll at hand. A female taken on the 

 Bolcan Mountain approaches it and connects it with the typical speci- 

 mens. Casey's specimen has the buccal processes very slightly promi- 

 nent and not narrowed. It is without doubt heterotypical of the 

 present species; in form it agrees with a male in Mr. Blanchard's 

 collection. 



It should be noted that the elytra are shorter than in consohrimi. 



I take great pleasure in remembering the kind and painstaking aid 

 accorded me by Mr. Frederick Blanchard. 



General observations. — The mentum is comparatively large, but 

 variable in size, slightly transverse and parabolic in outline, some- 

 times less strongly rounded at the sides; surface rather broadl}' 

 convex at the center and narrowly subfoveate within the lateral mar- 

 gins; not noticeably setose. 



Pro- and mesosternum as in consohiina. The metasternum laterally 

 between the coxse is as long as the width of a mesotibia at the middle. 



The abdominal process is sub(|uadrate, and a fifth (fenuile) to a 

 third (male) of its width broader than the metasternal salient, also 

 equal to the post-coxal part of the same segment, equal to the length 

 of the third (female). 



In the male the second segment is twice as long as the fourth, the 

 third being a third of its own length longer than the fourth. 



In the female the second is twice as long as the fourth. 



The tarsi are of moderate length and not as stout as in coiisobrina.
