ON THE AFFINITIES OF NEOLARRA. 

 By CARL F. BAKER, Fort Collins, Colo. 



In Bulletin I of the Colorado Biological Association, Mr. 

 Ashmead erected the genus Neolarra on a unique male hymen- 

 opterous insect collected by Mr. Cockerell at West Cliff, Custer 

 Co., Colo., and named the species pruinosa. Following the 

 description he says: "This remarkable insect exhibits strong 

 Larrid affinities in shape, general appearance, and in the par 

 tially aborted ocelli, and I was inclined at first to place it in the 

 Larridcc^ but the distinctly produced labrum, only noticed when 

 describing, induced me to place it finally with the Bembecidce ; 

 and it will probably form a distinct tribe in this group, although 

 in its wing characters it is entirely different from any Hymenop- 

 tera known to me." Later, Mr. Fox borrowed the unique type 

 and in Entomological News, IV, p. 292, published a figure of 

 the wing and a fuller generic description, rightly calling the type 

 a male instead of a female, as described by Mr. Ashmead. Re 

 garding its affinities, Mr. Fox says: " I quite agree with Mr. 

 Ashmead in stating that it will probably form a distinct tribe of 

 the Bembecidce (so-called), and go further and believe it to 

 represent a distinct group intermediate between the so-called 

 jBembecidce and Larridcz. As several authors have demon 

 strated that the Larridce and Bcmbccida are not entitled to 

 family distinction, representing nothing but groups of the Sphec- 

 idce, the discovery of Neolarra tends to make the assertion 

 stronger. While its affinities to the Bembccida are shown in the 

 strongly protruding labrum and form of the mandibles, yet its 

 relation to the Larrites is evident in the wings, which are not 

 very dissimilar to the genus Dinetus." 



During the past summer I collected specimens (male and fe 

 male) of this species at Fort Collins, on the flowers of Eriogo- 

 num microthecum var. effusum. A little later I took a single
