of darkened border of the median nervules extending into the tails is 

 so widened as to nearly include the entire area of the latter. The 

 whitened areas are, in many instances, somewhat suffused, particularly 

 at the apex. The aberration is repeated upon the under side, except 

 that in the secondaries the white indentations are more extended lat- 

 erally, the heavy border of the intersecting veins being proportion- 

 ately decreased except toward and at the edges. The right tail also 

 is deeply invaded by white, while the left retains the original hue. 



It is extremely difficult to convey by means of a photograph or 

 description a clear conception of the odd and striking appearance of 

 the butterfly. Had it been taken in free flight in a remote locality 

 without previous knowledge of its origin, it could not but have occa- 

 sioned much curiosity and discussion. The accompanying figures 

 were drawn by Mr. Charles J. Martin, of Brooklyn. The type is in 

 the collection of Mr. Wasmuth. 



TWO NEW BEMBICINE WASPS. 

 By William J. Fox. 

 Bembex beutenmulleri, sp. nov. 



^ . Deep black throughout without pale marks on tliorax or abdomen ; jni- 

 bescence of head and thorax rather conspicuous, cinereous ; clypeus except a crescentic 

 basal black spot, labrum, mandibles except base, line on scape beneath, flagellum 

 beneath entirely, or with each joint spotted (or again entirely black) inner orbits, 

 tips of all femora, a line on anterior and middle tibiae, and a spot at apex with no hind 

 ones, yellow; wings hyaline, veins testaceous. Front narrow, distinctly more so than 

 B. aniana, to which this species is related ; clypeus convex, quite short medially, 

 owing to the strongly incurved fore-margin ; eighth antennal joint bidentate ; medial 

 femora smooth, not serrated, the lower margin rather sharp, their tarsi much longer 

 than their tibioe ; second ventral segment finely carinated down middle ; sixth ventral 

 with two elongate, parallel tuVjercles, varying in strength ; seventh produced into an 

 acute spine. Length, 17-18 mm. 



Habitat : Fresno County, California. Four specimens collected by 

 the late Henry Edwards, a,nd now in the collections of the American 

 Museum of Natural History. It comes closest to Bembex amoena, 

 though it is related \.o priinosa and occidentalis in spined seventh ventral 

 segment. 



It has a strong superficial resemblance to Bembex cinerea which is 

 quite distinct from it, and has so far been recorded from Georgia
