156 W. H. ASHMEAD. 



finely striate ; seutellum with two deep fovese at base, separated only by a slifjht 

 carina, a deep median groove extends from them and slightly up the spine. 

 Wings hyaline, free from pubescence, the veins so delicate and pale as to be only 

 visible when seen through transmitted light, the anterior wings are broad and 

 the marginal cell is broad. 



Described from one specimen taken at large. 



ASPICERA Dahlbom. 



55. Aspicera albiliirta n. sp.— J. Length .14 inch. Black, scabrous, 

 shining. Head rugose or carinated, a prominent carina extends from base of 

 each antennae, along the anterior orbits of eyes: ocelli prominent, with a de- 

 pression or fovea behind and then transverse! y,carinated ; a depression at base of 

 antennae : the face and cheeks covered with dense white pile ; antennae short, 

 1.3-jointed, filiform, brownish yellow; first two joints black, others elongate, 

 third slightly shorter than fourth, about equal with fifth, others subequal, the 

 terminal one being very long and the longest joint. Thorax transversely rugose 

 and carinated, parapsides distinct, converging behind, bordered by a carina, a 

 median carina between separated by two carina before reaching base of seutellum, 

 thence as a deep groove ; anteriorly there are two short, oblique carina, ending 

 abruptly before reaching the middle carina; a deep longitudinal groove at base 

 of wings; prothorax large, hind margin emarginate with two oblique carina of 

 the mesothorax, sides hairy, mesopleurse alone being smooth and polished ; seu- 

 tellum large, quadrate, ending in a long spine, two deep approximate foveas at 

 base, separated by a narrow carina, the surface reticulately rugose; metathorax 

 covered with dense white pile. Legs brownish yellow, tibiae sparsely pubescent, 

 posterior tibiae longitudinally carinate on inner side, the basal joint of posterior 

 tarsi is cylindrical, stout, as long as all the others combined. Abdomen ovate, 

 black, polished, but only slightly compressed, with a striate girdle at base. Wings 

 hyaline, veins pale, slightly yellowish, the marginal cell open, the subniarginal 

 and marginal vein not being prolonged to the marginal edge. 



Described from one specimen taken while in the act of depositing 

 an egg in a dipterous gall. 



,56. Aspicera siinilis n. sp. — 9- Length .10 inch. Sculptured as iu 

 Aspicera albihirfa, but differs as follows : size much smaller, antennae and legs of 

 a more decided yellow, first two antennal joints not black, third joint is as long 

 as fourth, the terminal joint being two and a half times longer than the pre- 

 ceding joint and brownish; the pubescence while similar is not so dense; the 

 thorax is smooth, for while the sculpture is v'ery much the same it is not so trans- 

 versely rugulose; the seutellum, too, while ending in a long spine is not reticu- 

 lately rugose or carinated, there being three longitudinal carina, a central one 

 extending up the spine, and two lateral ones; finally, the veins in the wings 

 are so pale as to be hardly perceptible. 



Described from two specimens captured at large.
