282 HYMENOPTERA. 



abruptly larger, nearly twice wider than the pedicel, ovate, with longi- 

 tudinal grooves and as long as the combined lengths of the three proxi- 

 mal funicle joints. Along the whole of one side are grouped white 

 dots, apparently setigenous spots, and in other aspects seen to be 

 minute stiff setae. Ptibescence rather long, soft hairs on funicle, very 

 short on club and closer.

 5. Auaphes nigrellus species nova. 



Normal position. 



Female. — Length, 0.75 mm. Moderately small but robust, short and 

 stout. Fore wings moderate in width, not curved. 



General color Van Dyke brown to blackish ; the antennae and legs 

 dull olivaceus, the trochanters and knees pallid ; the eyes very dark ; 

 wings fumated as in sinipetmis ; coxae exteriorly somewhat darker. 



Fore wings not curved, moderate in width, their greatest width sub- 

 equal to their longest marginal cilia, their discal ciliation moderately 

 fine and dense, arranged in from ten to twelve longitudinal lines across 

 the widest blade portion and limited proximad as in the former spe- 

 cies. Marginal vein as in the former species ; distad just before apex, 

 caudal margin of fore wing nearly straight, the cephalic margin con- 

 vex. About sixty-five marginal cilia. Posterior wings as in sinipennis 

 but slightly more curved and wider, bearing the usual paired line of 

 discal ciliation along the caudal edge of the wing but that of the 

 cephalic edge is single after it reaches half-way to the venation ; its 

 longest marginal cilia are subequal in length to the longest of the fore 

 wings or slightly shorter, and they are about three times longer than 

 the average width of the blade. Posterior wings nearly as long as the 

 cephalic ones. The secondary marginal ciliation present in the fore 

 wings. In the midlongitudinal line of the posterior wing is a line of 

 from four to ten discal cilia running from the apex. 



Abdomen globate-ovate, smaller than the thorax, sessile, the valves 

 of the ovipostor not at all prominent or exserted. Tibial spurs minute, 

 single (?), those of the cephalic legs larger, two-tined at tip and form-
