the last joint sessile and closely united with the penultimate, the glo- 

 bular part of the flagellar joints, and also the verticils, coal-black in- 

 stead of being merely tinged with dusky, and towards the tip of the 

 antennae the former are alternately small and large, but in a somewhat 

 irregular manner, the larger ones full i longer and wider, the smaller 

 ones scarcely shorter and narrower than in atrocularis. That it may 

 not be supposed that the difference in color of the globular joints is 

 caused by the degree of maturity, the most mature insect as usual be- 

 ing the darkest colored, it is proper to say here, that one of my S atro- 

 cularis, which species has the paler antenna;, is decidedly more mature 

 than my atricornis which has much the darker antennae. 2mJ. The 

 legs have the femora superiorly black, otherwise as in atrocxdari». 

 Srd. As in the following species, there is no cross-vein whatever be- 

 tween the 1st and 2nd longitudinal veins, even when the wing is held 

 up to the light under the strongest lens. — Length % .1)5 inch. Wing 

 Z .07 inch. One % , reared from ^S'. strobiloide.s galls in the first week 

 of September, along with the preceding and following; 9 unknown. 

 It might be supposed to be the % of the following, but for the total 

 absence of the 3 spots on the wings, and other differences pointed out 

 under that species. 



F. D. ANNULIPES n. sp. (Dried.) 9 Differs from the 9 of atro- 

 cidarls only as follows : — Is^ The antenna; 9 are nearly as long as the 

 dried body, 12-jointed (2-j-lO) both in the recent and in the dried 

 specimen, instead of 13-jointed, the flagellar joints globular towards 

 the tip, only slightly oval towards the base, the last joint nearly twice 

 as long as broad and tapered to an acute point; the verticils 1 — 1] 

 times as long as the complete joint from which they spring, instead of 

 being only f as long. 2nd. The legs do not have the femora black above 

 as in atricornis, though as in some atrocularis the tibiae are occasion- 

 ally a little obfuscated above; but they difi'er remarkably from both 

 species in the terminal j or 1 of the 2nd or elongated tarsal joint, and 

 the whole of the 4th and 5th tarsal joints being black, the intervening 

 8rd joint being whitish and thus displaying a conspicuous white anuu- 

 lus, whence the specific name. Sr^Z. There are 3 obscurely bounded, 

 pale-dusky spots on the wing, caused by a greater density of the pubes- 

 cence which is dusky, viz. one subquadrate spot placed f of the way to 

 the tip of the wing and extending from the 2nd longitudinal to the
