 Aldrich collected at Havana, Cuba (Baker). 



Type.—Kide, Cat. No. 41987, U.S.N.M. 



This species is not so closely related to the genotype as ahdominalis^ 

 but is referred here principally because it has about the same type of 

 postscutellum as hicolor. The main characters in which it differs are 

 the presence of anterior acrostichals, and the large horizontal cruciate 

 f rontals above base of antennae.
