292 ENTOMOLOGICAL NEWS. [November, 



and on the next, when the storm was subsiding, I came down the 

 mountain. I expect to print a complete list of the insects cap- 

 tured during my two visits to the Summit. They have been 

 identified by Mr. Liebeck, Mr. W. J. Fox, Mr. G. C. Davis, Mr. 

 Van Duzee and others. And I am deeply indebted to them all 

 for their assistance. The heaviest burden has devolved upon 

 Mr. Liebeck, as the number of Coleoptera far exceeded that of 

 any other order, amounting to about one hundred and twenty 

 species. 



Observations on the Hymenopterous Genus Neolarra Ashm. 

 By William J. Fox. 



In the Bulletin of the Colorado Biological Association, No. i, 

 1890, p. 8, Mr. William H. Ashmead has described an interesting 

 new genus of the Fossorial Hymenoptera. Through the kind- 

 ness of the above-mentioned gentleman I have had the opportu- 

 nity of examining the unique type, from which I have made the 

 observations contained herein and have drawn up the appended 

 description. I quite agree with Mr. Ashmead in stating that it 

 will probably form a distinct tribe of the Bembecidae (so-called), 

 and go further and believe it to represent a distinct group inter- 

 mediate between the so-called Bembecidae and Larridae. As 

 several authors have demonstrated that the Larridae and Bembe- 

 cidae are not entitled to family distinction, representing nothing 

 but groups of the Sphecidae, the discovery of Neolarra tends to 

 make the assertion stronger. While its affinities to the Bembe- 

 cites 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 Dineius. I 

 might state that the type is a S , and not a 9 , as supposed by 

 Mr. Ashmead. 



Description. — Head as broad as the thorax; mandibles broad 

 at base, narrow and acute at apex, not emarginate on outer mar- 

 gin; labrum triangular, a little broader at base than it is long; 

 the clypeus seems to be divided into three lobes, the middle one 

 being by far the largest, most prominent, and extends up between 

 the insertion of antennae; eyes rather strongly diverging towards 

 the vertex, their inner margin entire; antennae short, the pedicel
