H. C. FALL 375 



The locality named by Olivier in his original description is 

 "Carolina." Haldeman says "Middle and Southern States," 

 and adds, "In Pennsylvania it appears in June and July on trees 

 of the genus Carya." It is by no means certain, however, that 

 Haldeman's femoratus is the species here described, his charac- 

 terization being short and about equally applicable to several 

 other Atlantic Coast species. For the same reason Olivier's 

 description is of little value and I have thought it the best course 

 to accept as femoratus the species so labeled in the LeConte Col- 

 lection. This agrees well enough with the original description 

 as well as with those of Haldeman and Suffrian, and is a common 

 species in the region from which Olivier's type is reported to have ' 

 come. 



In the northeastern States the following variety to a large 

 extent replaces the more typical form of the southern States. 



Var. aquilonis new variety 



Legs darker, sometimes almost entirely black, the hind tibiae quite con- 

 stantly dark brown or blackish throughout, while in true Jemoratus they are 

 always yellow in about the basal half and more or less so at apex. The black 

 color is more strongly predominant as a rule (though with numerous excep- 

 tions) than in typical femoratus, the pale spots of the pygidium smaller and 

 often absent, and that at the side of the last abdominal segment is here rarely 

 present (constantly present in ivxie Jemoratus).

59. Pachybrachys characteristicus Suffrian 



Dull grayi.sh or whitish yellow, thickly speckled with brown or 

 fuscous diffused punctures, and with brown or fuscous markings 

 which are very variable in extent and distinctness, elytral striae 

 indistinct and unimpressed except on the convexity; lateral inter- 

 space as a rule wider posteriorly than the next inner one; other 

 characters as in femoratus. Ave. length 3 mm. Florida. 



This species is very closely related to femoratus and there is little to add in 

 the way of distinction to the above diagnosis. The color when not obscured 

 by the markings is distinctive; the standard M is sometimes nearly fuscous 

 in color and is then quite sharply outlined; more often, however, it is of some
