the markings white instead of yellow. In the northern counties 

 and again in the south, the males have a tendency to have also a 

 rather faintly defined crescentic line at the middle of the elytra 

 and in addition a general suffusion of yellow hairs over the elytra. 

 The specimens with the median markings are more common in 

 the north and the specimens with the yellow suffusion best de- 

 veloped in the south as about Los Angeles. These are of course 

 but mere races for typical forms are to be found with them as 

 well as intergrades. Colonel Casey's incongruus is the northern 

 sluffused form and his X. disruptiis, the female of one of the 

 southern phases. There is also another and quite distinct race 

 which was secured in numbers by Mr. F. W. Nunenmacher, at 

 Kirby, Josephine Co., Or., June ii, 1910. The specimens were 

 all males, of the usual rufous color with the prothorax, but 

 slightly peppered with white hairs and the elytra sometimes with 

 and sometimes without white oblique bars, with either transverse 

 median white spots or bars, the subapical white bar always pres- 

 ent, and in addition a general peppering of the surface with white 

 hairs. This I consider a distinct geographical race for which I 

 propose the subspecific name nunenmacheri_ after its discoverer. 

 Insignis lives entirely in willow as far as I know and has the 

 habit, particularly the males, of often resting on various plants 

 like the thick-leaved milkweeds and mullens. Mr. J. J. Rivers was, 

 I believe, the first to breed out the beetle from its food tree and 

 prove the specific identity of the two sexes. I have also bred it 

 and dug out colonies on numerous occasions and in various parts 

 of the state. X. obliteratus Lee, described from Colorado and 

 for some time considered to be the male of insignis, appeared to 

 me, after a very careful examination of the type, to be rather 

 more closely related to X. mormoniis Lee, perhaps a phase of 

 that Rocky Mountain species. 



Leptura scapularis n. sp. 



Short, black, with triangular orange red patches at the humeri and a 

 small tail-like appendage extending on to the epipleurse, with short, rather 

 sparse gray pile covering all of the body except the black portions of the 

 elytra and most evident on the pronotum and underside, and a black pile 

 covering the black parts of the elytra. Head with mouthparts but moder- 

 ately prolonged, broad between the eyes, not very suddenly constricted
