 ocidatus.

THROSCID^. 



PACTOPUS Lee. 



The two species of this genus, which are indicated by the mate- 

 rial in my cabinet, may be distinguished thus : — 



Very elongate, the elytra more than twice as long as wide ; prothorax strongly 

 enveloping the humeri, the sides deeply sinuate anteriorly, as well as con- 

 vergent ; eyes larger, separated by about twice their own width. Length 

 4.6 mm. ; width 1.6 mm liorni Lee. 



Less elongate, the elytra not more than twice as long as wide, the eyes rather 

 smaller, separated by distinctly more than twice their own width ; protho- 

 rax a little less strongly enveloping the elytral humeri, the sides strongly 

 conveigent to the apex but only very feebly sinuate. Remaining characters 

 nearly as in horni, the intermediate coxse very slightly more widely sepa- 

 rated. Length 3.2-4.2 mm. ; width 1.3-1.6 mm. California (San Francisco 

 and Sta. Cruz Cos.) fliclisi n. sp. 



Of fvchsi, I have three specimens, similar among themselves 

 but differing greatly in size; they were very kindly presented to 

 me by Mr. Chas. Euchs of San Francisco, to whom I take pleasure 

 in dedicating an interesting addition to the family. My four ex- 

 amples of hoi^ni are more uniform in size, and are from Washing- 

 ton State and Nevada ; it is probably more boreal in habitat than 

 fuchsi. 



CERAMBYCIDiE. 



A]VC¥LOCERA Serv. 



In general facies the species of Ancylocera are very similar 

 among themselves, and the two separated below are identical in 

 coloration; they may be distinguished as follows :-^ — 



Antennae of the female two-thirds as long as the body ; flanks of the prothorax 

 transversely rugose as far as the coxse, where the plications abruptly ter- 

 minate, the prosternum before the coxse very coarsely punctate.
