%>.'.— No. 6377, U.8.N.M. 



Cotypes in collection of Mr. William D. Kearfott. Very similar 

 to the preceding species, but at once distinguished l)y the white basal 

 costal patch.

Cotypes in collection of ^Ir. William D. Kearfott. 



Very similar in size and general habitus to the two foregoing spe- 

 cies; so similar that by superficial examination thev might all be taken 

 to represent one species, which, however, the constancy in their dif- 

 ferences clearly shows that they are not. The present species is 

 easily recognized ])y its peculiarly colored abdomen, as well as by the 

 isolated triangular costal black spot.
