able and they cause considerable profanity to float out on the 

 otherwise pure air. Breeds in yellow pine, Douglas fir and 

 the true firs (Abies). 



20. Melanophila atropurpurea Say.* 



I have assigned thirteen specimens, taken at Weed, to this 

 species. I must confess, however, that the difference existing 

 between M. lomjipcs, M. acuminata and M. atropurpurea is 

 almost nil in my judgment. The separation I have made is 

 based on the shape of the prothorax and the difference here 

 grades from one extreme to the other until it is a mere guess 

 where one species stops and another begins. Statements un- 

 der M. longipes apply to the species also. 



21. Melanophila drummondi. 



Less common in California than in Oregon. Breeds freely 

 in Douglas fir, grand fir (Abies grandis} and to some extent 

 in yellow pine. 



22. Melanophila gentilis Lee. 



This beautiful species was not uncommon, but was rather 

 more active than any of the others and a capture of two speci- 

 mens out of every five was a good record. Thirty-six speci- 

 mens were taken; fully one-half of these were taken from the 

 bark or debris on the cars after the logs were unloaded. This 

 species, like Chalcophora angulicollis, will rest immovable for 

 hours where they are exposed to the direct rays of the boiling 

 sunshine. In cloudy weather neither species is seen. I find 

 my specimens collected in California are slightly larger and 

 less bright in color than specimens collected by Professor 

 Wickham in Arizona. Breeds in yellow pine. Ralph Hopping 

 states that it also breeds in P. lambertiana. 



23. Melanophila sp. 



A peculiar Melanophila, which Dr. Van Dyke believes is a 

 western form of M. pini-ednlis Burke, was taken by him at 

 Carrville, Trinity County, California, in July, 1913, and at Mc- 

 Cloud. Siskiyou County, in July, 1914, on yellow pine. 



*It is possible that the true atropurpurea was not taken and the 

 specimens here mentioned are mere phases of M. lonyipcs.
