CERAMBYCID/E 205 



The single male type has been in my cabinet for many years 

 under the name Leptura valida Lee.* The original female type of 

 the latter, from Shoalwater Bay, near the Columbia River, as 

 figured, is very much stouter and has the sides of the prothorax more 

 prominent medially; the prothorax is said to have fine dense punc- 

 tures, intermingled with some that are coarse and sparse, and the 

 elytral spots are nebulous and in three series. In oculea the thoracic 

 sculpture seems to be different, the penultimate palpal joint much 

 shorter, and the elytral spots are smaller, sharply defined and in 

 two series only, there being no trace of maculation behind the 

 middle. Having in mind the differences noted, in conjunction with 

 the different conditions of environment between the northern sea- 

 coast, and 6000 feet elevation in the southern Sierras, it is to be 

 presumed that the two species are different. But, in any event, it 

 is quite certain that this type forms a distinct genus in the neighbor- 

 hood of Leptalia and Centrodera and is distinctly out of place in 

 Leptura. In Leptura insignis Fall, from Monterey, which seems to 

 be congeneric, the elytral apices are rounded and wholly unarmed 

 and the elytral ornamentation somewhat more extended, showing 

 that the spiniform sutural angles do not constitute an essential 

 generic character, although unknown in Leptura. In the male of 

 insignis, the sides of the apical sinuate truncature of the abdomen 

 are acute but dentiform; in oculea they are much produced pos- 

 teriorly, slender and spiniform, this comparison being made with 

 a male of insignis in the National Museum ; valida is also represented 

 in that collection by several typical females, taken near the mouth 

 of the Columbia River. 



Stenocorus F?br. 



The use of the names Stenocorus, Stenochorus and Toxotus, in 

 the latest European catalogue, is erroneous in great part, but the 

 matter is cleared up very well by Aurivillius in his recent general 

 catalogue, where Stenocorns is shown to be the proper generic 

 name for our species now known as Toxotus Serv. The genus Sten- 

 ocorus forms a remarkably isolated group, because of the retraction 

 of the tib'al spurs, which occurs nowhere else in the tribe so far as 



* There is a female of oculea, from Placer Co., California, in the National Museum; 

 this female is much more slender than the same sex of valida.
