 Si/c 7.5-8 X 2-2..") mm. 



Taking the two varieties together, the species is known from 

 Y\ondsi'---^-^-^\ . North Carolina'^ District of Columbia^ New 

 Je^sey^ New York, Indiana^, Colorado^-^~^, Dakota-, Montana^, 

 Texas-"^^"^ Arizona', Neiv Mexico^ and Calif ornia^ In the east, 

 according to Mr. Barber, it is " well established, but rarely 

 taken by collectors, possibly because they do not know just 

 where to look for it — in sandy spots. " 



Two varieties are found in the United States, so different 

 in appearance that they may possibly prove to be distinct 

 species. They may be separated as follows: 



a. Tuga projecting ccphalo-laterad from tylus so that head appears to i)e 

 three-pointed; body with little or no gray pubescence, general color 

 black, marked with dark ferrugineous; head strongly depressed; caudo- 

 mesal tooth of pronotum minute var. apicalis 



aa. Juga scarcely projecting, indistinct as seen from above; body covered 

 with fine grey pubescence; general color gray-flavescent; head not 

 depressed; caudo-mesal tooth of pronotum prominent var. cinerous 



The typical variety {apicalis, Fig's 13, 13a) is piceous black. 

 slightly marked with dark reddish brown. It is eastern in distri- 

 btttion, ranging from Florida, the type locality, to New York. 

 Specimens from Florida, New Jersey and New York have 

 been examined. 



Stachyocnemus apicalis var. cinereiis n. var. (Fig's 14, 14a) 

 does not answer Dallas' description of the species in any particular. 

 It is flavescent in color, covered with dense fine white pubescence, 

 marked above with a large fuscous triangle on the pronotum. 

 The femora and venter are mottled, yellow and brown with 

 numerous small dots. 



Holotype : male from Fort Collins, Colorado. 



Allotype: from Gunnison, Colorado. 



Paratypes: male from LaSalle, Colorado; female from Fort 

 Collins, Colorado. All in the Ball collection. 



In addition to the type material the writer has examined a 

 considerable number of specimens of the latter variety from 

 Colorado; Hessville, Indiana; and Helena, Montana, in the 

 Gerhard collection, and one from the Huachuca Mountains of 

 Arizona from Mr. Barber. The types were taken at compar- 

 atively low^ altitudes in Colorado (5000 to 7000 feet) and were 

 found running about the surface of the ground. Dates of 

 capture include June, July, August, and September.
