haps closer to H. elegantula than it is to the other species assigned 

 to Hesperapis, and its rank as a genus appears doubtful. I think 

 we must call it Hesperapis (Zacesta) rufipes (Ashm.). 



Panurgomia Viereck, 1909, was based on P. fuchsi Viereck, from 

 Arizona. The unique specimen, a female, was unfortunately in 

 bad condition. Mr. J. C. Crawford recently wrote me (February, 

 1916) that he considered the genus identical with Hesperapis, and 

 the type species at least extremely close to H. eumorpha Ckll. 

 This led me to reexamine the type, and I found that it possessed 

 the essential characters, so far as could be seen, of the group of 

 Hesperapis which includes the majoritj^ of the species. The en- 

 tirely dull area of metathorax agrees with the minor group of H. 

 eumorpha, etc. The stigma is too large for typical Hesperapis. 

 The clypeus is large, strongly convex, polished and shining. 

 Hence it appears that Pariurgoniia is a valid subgenus (or genus.'') 

 for the group of Hesperapis which excludes the typical species. 



A NEW ENGLAND ORTHOPTERAN ADVENTIVE.

Hapithus vagus sp. nov. 



A large and rather stout member of the genus. Rostrum of the 

 vertex as broad as the basal joint of the antennae. Antennae, 

 except the basal joint, long and extremely slender, two or three 

 times as long as the body, pale brown, annulate with dusky on 

 alternate joints, every third annulus darker; this pattern is very 

 noticeable near the base and becomes indistinct apically. Max- 

 illary palpi with last joint slender at base, a little securiform, twice 

 as long as the width of the broadened tip. 



Pronotum transverse, narrowed anteriorly, the front margin 

 straight or slightly concave, the hind margin a little convex medi- 

 ally; lateral lobes twice as long as deep, smoothly convex below, 

 the anterior and posterior angles rounded. Tegmina nearly or 

 quite covering the abdomen, those of male flat 'above; of female a 

 little convex, with densely and irregularly reticulate venation, the 

 lateral field crossed by about seven parallel oblique branches of
