BY D. T. rULLAWAY. 



Apliycns terryi n. sp. 



$ Length of body 1.09 mm., expanse of wings 1.85 mm., greatest 

 width of forewing .37mm. Microspocilally reticulate and finely punc- 

 tured, punctures bearing short hairs; orange yellow, head, pronotum 

 superiorly and antennae paler (shading into white), scape below, 

 pedicel and first four funicle joints, pronotum anteriorly, scutellum, 

 metathorax and a broad band on abdomen infuscated (shading into 

 black). Head transverse, fairly wide anterior-posteriorly, indistinctly 

 lenticular, eyes large, somewhat bulged, front between, rather narrow, 

 face slightly retracted and widening immediately below the eyes to 

 meet the cheeks which are also rather broad below, ocelli arranged in 

 a slightly acute triangle, the lateral members close to margin of eye, 

 antennae arising just below middle of face, moderately long, with 6- 

 jointed funicle, scape long but not greatly widened below, pedicel 

 obconic, funicle joints extremely short but lengthening and expanding 

 outwardly, the last about half as long as wide, the club expanded and 

 indistinctly jointed. Pronotum extremely thin, mesonotum short, 

 about half as long as wide, without parapsides, axillae meeting in the 

 middle, scutellum almost triangular, apex bluntly pointed. Abdomen 

 conic ovate, collapsing after death so that the dorsal surface is 

 deeply concave, ovipositor slightly protruding. Legs moderate, middle 

 tibiae with long apical spur, tarsi with several rows of spines on inner 

 face. Wings hyaline, marginal vein short and thick, submarginal ex- 

 tremely long, reaching middle of wing, postmarginal a mere spur, 

 stigmal well developed, a hairless line reaching obliquely inwardly 

 from stigmal and a faint infumation below it. 



Male — Length about 1 mm., slenderer, the body and legs reddish 

 yellow, eyes red, antennae brownish black, scape beneath paler, 

 head thin, anterio-posteriorly and lenticular, eyes smaller, front be- 

 tween wide, lateral ocelli as far from margin of eye as from each 

 other, inner margin of eyes parallel and far removed, face widening 

 below to narrow cheeks, antennae arising far apart on level with 

 lower margin of eye (as in female), funicle long, as long as scape 

 and pedicel together, the joints submoniliform, first a little longer than 

 wide, width increasing on length outwardly but not becoming ex- 

 tremely transverse as in female, scape slender (not expanded leaflike, 

 as in female) nearly twice pedicel, club longer than pedicel by half 

 and rather thick. Thorax and abdomen rather depressed, the latter 

 acutely triangular, apex truncated. Wings hyaline, the fumation be- 

 neath the stigmal vein absent.
