302 HYMENOPTERA ACULEATA. 



silvery hairs, beneath ferruginous, eighth segment in the 

 (J with the apical process long, rather dilated at the apex, 

 with long reflexed apical spines; fifth segment in the ? with 

 a tuft of dark hairs on each side, legs piceous in the $ , 

 femora in front, knees and tibiee paler, ferruginous in the 

 ? , femora at the base, and the posterior pair beneath black, 

 posterior tibiae with two uneven spines near the outer 

 angle. 



L. G-7 mm. 



A very distinct species easily known from the others, 

 which have the labrum black, by its slender form, long, 

 pale antennee and the great length of their fourth

 and A. nana, although I did not actually see it enter the 

 burrows of either.
