20 CYRTIDAE OF NORTH AMERICA 



Philopota dolorosa 



Philopota dolorosa Williston, Biologia, Dipt., p. 298. 



"Very much like P. lugubris; but the frontal triangler is larger, reaching 

 midway to the ocelli; the abdomen is wholly without yellow, save the very 

 narrow lateral margins of the segments; the mesothorax also lacks the large 

 yellow spots, and there is only a small yellow spot on each side of the posterior 

 margin of the pronotum. The legs are black, with the knees and basal joints 

 of the tarsi reddish. Length 6-7 mm. 



"Hab. Mexico, Amula in Guerrero (H. H. Smith). 



"One specimen. I cannot believe that the strongly marked differences 

 between this and the preceding species are merely varietal, though such is 

 possibly the case. I am unable to determine the sex; it appears to be the 

 same in our examples in both forms." 



Philopota truquii 



Philopota truquii Bellardi, Saggio, i, p. 77, pi. 2, f. 20.
