longer. Front as described by Horn, slightly pubescent, clypeus with a 

 triangular oval emargination at middle, arcuate on each side. (This is. 

 exactly as Horn describes the female). I find that the clypeus of the 

 females varies considerably in all specimens I have seen but is usually 

 as shown in Figures I and 2. Thorax more angulated than one would 

 surmise from Horn's description, though fitting his figure admirably; 

 two depressions each side of middle and a third one near the margin, 

 center (I fail to find the crescentic or oblique depressions of Dr. Horn) 

 coarsely punctured, the punctures running together transversely, giving 

 a strigilated appearance. Elytra same as female, prosternum not lobed, 

 coarsely and closely punctate, margin of last ventral (Fig. 5) serrate; 

 tip deeply, semi-circularly emarginate, the emargination deeper than 

 wide. Anterior tibia dilated at end as shown in Fig. 6. Length 13 mm. 



A single male taken in Grant County, Oregon, July 21, 1914, 

 on lodge pole pine (P. contorta). This species probably breeds 

 in P. contorta, P. lambertiana and P. ponderosa. 



34. Chrysobothris pseudotsugae Van Dyke. 



One specimen taken in August. This species bears a close 

 resemblance to C. caurina, but is smaller and darker. The 

 prosternum being lobed will at once separate it from caurina. 

 Taken on Abies grand is, grand fir, at Weed, August u, 1915. 

 Hopping has taken this species from P. ponderosa. 



35. Chrysobothris laricis Van Dyke. 



This species described from a series collected by the author 

 in eastern Oregon on larch and lodge pole pine, and has been 

 taken in the lodge pole pine belt above Lake Tahoe and in 

 Tuolomne Meadows, California. It no doubt will be found in 

 the higher Cascade and Sierra Ranges from Oregon to Central 

 California. 



36. Chrysobothris nixa Horn. 



This species is fairly common in northern California and 

 ranges over into the southwestern portion of Oregon. Breeds 

 so far as known only in incense cedar (Libocedrus decnrrens). 



37. Chrysobothris viridicyanea Horn. 



This beautiful green species breeds in the limbs and smaller 

 branches of Libocedrus decnrrens and is found in most of the 

 northern counties of the State. The following counties are 

 represented in Dr. Van Dyke's collection: Trinity, Siskiyou 

 and Placer. I have two specimens from Siskiyou County.
