black, the scape yellow in front, first joint of flagelluni scarcely as long as second 

 and third together, last joint suhtruncate; niesothorax dull, minutely granular, 

 with close, very shallow punctures ; tegulse dark reddish testaceous. Wings 

 hyaline, nervures piceous, marginal cell minutely appendiculate. Legs black, 

 tarsi rufous (first joint of middle tarsi darker), claws black, except their bases; 

 pubescence of legs short, thin, wiiitish; middle legs slender, their tarsi simple; 

 hind femora and tibia* greatly swollen, tibia with a short, but stout, rufous, sub- 

 apical tooth on inner side; first joint of hind tarsi enlarged and flattened, cov- 

 ered with appressed dark rufous hairs within, with the inner margin presenting 

 a very large tooth with a broad base, but acute point (like a rose-thorn), below 

 which, apically, is a small tooth. Abdomen coal-black, with the hind margins of 

 all the segments broadly ivory-white; there is short, inconspicuous, black pubes- 

 cence on the black portions, but no pale hairs, except the fulvous hairs of the 

 first segment, and appressed silvery pubescence on the hindmost portion of the 

 sixth segment and covering the apex, the same silvery pubescence being continued 

 up the sides of the abdomen beneath. 



Hab. — Two at flowers of Gesalpinia falcaria in the grounds of 

 the Canaigre factory, Deniing, New JNIex., July 9, 1896. 



Tliis resembles P. cleomis, but is at once distinguished by the face- 

 markings, the color of the pubescence, etc. From P. tricolor it will 

 be known by the legs. From P. tarsatus by the want of black pu- 

 bescence on the dorsulum, and by the color of the legs. It seemed 

 to differ from Cresson's callfornicus by the pale griseous or whitish 

 pubescence of the legs, the large amount of yellow on mandibles, 

 and the bright yellow face-marks ; but Mr. Fox assures me that it 

 is in reality the same species. I give a redescriptiou, as Cresson's 

 description is hardly adequate. 



(20.) Podaliriiis cardiii n. sp. % .—Length about 13 mm., anterior wing 

 10 mm. Black, with gray pubescence, dense on thorax, except dorsum of meta- 

 thorax. which is bare and shining; dense also on cheeks and occiput, but sparse 

 on front and altogether absent on the white parts of the face ; a few black hairs 

 on vertex, none on thorax. Head broad, face nearly square, vertex somewhat 

 shining, but minutely roughened, clypeus dullish, sparsely punctured above, the 

 punctures becoming larger and closer on apical half; labrum somewhat shining, 

 irregularly and subconfluently punctured ; clypeus, except a black spot on each 

 side above, and the narrow anterior edge, a transverse supraclypeal band, lateral 

 face-marks shaped like the side view of a shoe with a pointed toe and a large 

 flap; labrum, except a black spot on each side above, and the narrow anterior 

 margin, a large subpyriform spot on mandibles, and a large elongate mark on 

 scape, all ivory-white; first joint of flagellum about as long as the second and 

 third together; mesothorax dull ; tegulse large, dark brown, margined with hairs. 

 Wings hyaline, slightly brownish in first submarginal cell, nervures brown. Legs 

 slender, simple, small joints of tarsi more or less rufous; pubescence of legs sil- 

 very whitish, hardly moi-e than a sparse fringe on femora, a slight priiinosity on 

 anterior tibise, a conspicuous white fringe on outer margin and a smaller one on 

 inner margin of middle tibite ; hind tibiai with the whole outer side hairy ; tarsi
