at 5,000 ft. This latter was in its own burrow and there 

 would seem to be no doubt that Libocedrus is a food tree of the 

 species. ' ' The sixth specimen bearing the label ' ' Three Rivers, 

 Cal." is from the same region, and was recently submitted 

 without notes by Prof. C. F. Baker. I learn on inquiry that 

 Mr. Fuchs has a single 9 of this species from Seattle, 

 Wash. , and there is also a " W. T. " example in the Horn 

 collection. Miss Julia Wright has taken two examples at 

 Towles, Placer Co., Cal., (fide Blaisdell). Dr. A'an Dyke 

 says, " I have never collected a live Trachykele, but have two 

 green wing cases, one taken from, I think, a yellow pine 

 stump at Sesson, Shasta Co., the other in Tuolumne Co." 

 (California). 



T. blondeli Mars. 



The description of Marseul applies about equally well to the 

 species above described, and to a form of which I have seen 

 two examples received by Dr. Fenyes from Santa Fe. , New 

 Mexico. Specimens of each were accordingly sent to Mr. 

 Frederick Blanchard, who has kindly compared them with 

 the blondeli elytra in the LeConte collection. Mr. Blanchard 

 reports that the Santa Fe specimen is of a more brilliant green 

 but otherwise so closely in accord with blondeli that he thinks 

 there can be scarcely a doubt of their identity. The two 

 species are quite similar in most respects, but on comparison 

 blondeli differs plainly from opulenta in its distinctly coarser, 

 less dense punctuation and consequently more shining surface, 

 in the more strongly angulate lateral crest and deeper excava- 

 tions of the pronotum. There is on each elytron of blondeli 

 at about two-fifths from the apex and midway between the 

 suture and side margin, a small transverse impunctate carini- 

 form elevation or tumidity, no trace of which exists in ^ptiloita. 

 Some other small differences are observable but they are com- 

 paratively unimportant and perhaps not constant. The Santa 

 Fe specimens are respectively 14 and 17 mm. in length; the 

 L/eConte elytra indicate a still larger specimen. It is quite 

 probable that the Santa Fe species ranges south into Mexico, 

 and to this extent tends to confirm the locality given by \Vuter-
