appearing microscopically tessellated. Femora black, with pale yellow distal 

 ends; anterior and middle tibiae pale yellow with a black patch behind; hind 

 tibise much longer, with long hairs, and almost all black ; anterior and middle 

 tarsi pale yellow, hind ta-rsi black ; tegulffi very pale yellow. Wings fairly ample, 

 hyaline, nervures and stigma piceoiis, almost black, nervures all very distinct; 

 stigma not at all pale in the middle ; marginal cell short, not longer than stigma ; 

 second snbmarginal greatly narrowed above, practically triangular. Abdomen 

 with the first dorsal segment black, with a small, transverse, yellow band, broken 

 centrally and not reaching the sides on the disc; second, third, fourth and fifth 

 segments with their their distal half (or more) black, and the proximal half pale 

 yellow, the bands not united in the middle line, nor conspicuously indented . 

 venter dirty yellow, with a pair of dark oval spots on each segment.

The shape of the second .subniarginal cell is like that of P. arcaata 

 Fox, but F. iinmemtu is totally distinct by its face markings from 

 any other species that I know of. The number 11 on the clypeus 

 will at once distinguish it. 



DESCRIPTIONS OF x\EW HYMEXOPTERA. 



BY T. D. A. COCKERELL AND J. E. CASAD. 

 (With Notes by VVm. J. Fox.) 

 Sphierophtlialiiia wicliliaiiii n. sp. 9- — About 10 mm. long. Head 

 large, a little broader tlian thorax, quadrate seen fi-om above, subcircular seen 

 from in front ; color orange-brown ; face and crown strongly punctured, covered 

 with appressed shiny orange-red hairs, with blackish, erect hairs interspersed, 

 the latter longest above the eyes ; clypeus with long, pale yellowish hairs; man- 

 dibles shiny rufous with black tips. Antennte brown, blackish towards tips, fir.st 

 joint of flagellnm a little longer than second. Thorax orange-brown, punctate, 

 becoming strongly reticulate on metathorax ; strongly constricted at sides : mar- 

 gin above the smooth and shiny lateral excavations dentate ; pubescence similar 

 to that of head, but jiot so dense on pro- and mesothorax, but anterior part of 

 prothorax and greater part of metathorax bare : coxae and femora orange-red, 

 tips of femora blackish ; tibise and tarsi blackish, more or less covered with pale 

 yellowish shiny hairs; tarsal spines rufous, tibial spurs whitish, minutely ciliate. 

 Abdomen pyriform, first segment broad and sessile, orange-red basally and nearly 

 destitute of hairs, but distal half dorsally covered by dense, appressed, shiny, pale 

 golden hairs; second segment black, finely punctate, with a slight median golden 

 streak on its anterior third ; a large squarish, pale golden spot on each side, and a 

 rather broad, median, pale golden fringe on the posterior margin; the last-men- 

 tioned fringe occupies about the middle third of the margin of the dorsal portion 

 of the segment, the remaining part of the margin being black, except a small 

 golden patch on the extreme lateral iiortion ; the large pale spots are further from 

 each other than the diameter of either; remaining segments black, heavily 

 fringed with pale golden hairs, except the last, which has the hairs orange-red ; 

 ventral surface of abdomen with pale hairs ; that of second segment strongly 

 punctate and rufous. 



Hah. — Houston, Texas (H. F. Wickham) ; one specimen. 



This species is allied to *S'. quadrkj attata Say, which it resembles.
