as californica, to which indeed they are very closely related, but the 

 latter species is in my experience never truly black as is the present 

 one, and the pubescence is more fulvous. The terminal joint of the 

 antenna? in the female of blanchardi shows a slight tendency toward 

 the form in the male by being slightly sinuate within, but this ten- 

 dency, observable in the types, may not hold in larger series. The 

 frontal costa is very vague, and is caused by the side slopes of the 

 front meeting in a very obtuse and ill defined angle, which is usu- 

 ally marked by a narrow smooth line and only visible when viewed 

 from the side. This frontal line is more or less evident in a number 

 of species, but seems to be entirely wanting in oculata, similis, later- 

 alis, inepta and frontalis. 



7. C. californica Lee. — Form a little less broadly rotundate than in 

 oculata and distinctly smaller; color varying from castaneous to piceous brown; 

 pubescence fulvous. Palpi nearly as in blanchardi. Terminal joint of antennae 

 slightly sinuate on the inner side in the male ; not sinuate, and relatively a little 

 less elongate as usual in the female. Punctuation a little finer and closer than 

 in oculata. Length 1.5-1.9 mm. 



This species occurs on live oaks in California from the vicinity of 

 San Francisco to San Diego. The species described above is that to 

 which Casey gave the name occidens. He refers under his descrip- 

 tion to a black specimen with more densely punctate thorax from 

 " Yountville, Napa Co ," which he conceives to be the true, califor- 

 nica. LeConte does use the term " black " in his description and 

 speaks of the thorax as more densely punctured than in oculata. 

 Mr. Blanchard writes me, however, that the type is somewhat brown- 

 ish, and as there is some individual variation in the punctuation of 

 the thorax in this species I have no doubt that LeConte's species is 

 the one here described. I have seen nothing corresponding with 

 Casey's Napa County black species, unless it be the Oregon form 

 referred to under blanchardi. The thorax is not notably more 

 densely punctate in that. 



8. C neomexicana. n. sp.— Very similar to oculata, from which it differs 

 as follows: Head very vaguely subcostate; punctuation of upper surface denser; 

 terminal joints of palpi slender, that of the maxillary palpus more than twice as 

 long as wide, and that of the labial palpus obviously longer than wide. Length 

 1.7-2.5 mm.
