during the summer. Forty-six specimens were taken. They 

 are very uniform in color and sculpture. Most of the speci- 

 mens were taken on logs floating in the mill pond. Dr. Van 

 Dyke says of this species : "Probably the most common yel- 

 low pine Chrysobothris we have in northern California and 

 eastern Oregon. Farther south in California it becomes scarcer, 

 its place being taken by C. monticolac Fall. Undoubtedly 

 breeds in yellow pine." 



32. Chrysobothris monticolae Fall. 



The species has a more delicate color than most of our 

 other western species. It tends towards a lilac, sometimes 

 hinting at a rose tint and in nature has more or less of a white 

 powdery coating which, however, is easily removed by care- 

 less handling. Two specimens, July and August. Breeds in 

 lodge pole pine. 



Weed is about 200 miles northwest of Lake Tahoe, which is 

 the most northern point hitherto recorded for this species. 



33. Chrysobothris dolata Horn. 



Two females were taken at Weed in July. Four specimens 

 of this species were taken in Grant County, Oregon, in July, 

 1914; three are females and the fourth a male. A close study 

 of the six specimens at my disposal shows a wide variation and 

 may possibly include more than one species. The five females 

 exhibit four different forms, which will be more readily under- 

 stood from the figures than from a printed description. Figure 

 i is the clypeus of var A., Fig. 10 is the thorax of the same 

 specimen ; 2 and 2.0, are clypeus and thorax of var B., etc. Aside 

 from the variation in clypeus and thorax there is little differ- 

 ence in the specimens. The antennae of I and 4 are dark 

 cupreous, while 2 and 3 are green ; i shows no callosites on 

 the front ; i and 3 are not as densely pubescent as 2 and 4. 

 All show the same sculpture and all are of an iridescent violet 

 color beneath. The prosternum of number 4 is a little more 

 coarsely and deeply punctured than the others. Numbers 2 

 and 4 are from eastern Oregon, while numbers i and 3 are 

 from Weed, California.
