322 A. L. MELANDEE. 



taceous; head rounded, eyes facetted, mandibles short, strong and pointed, flagel- 

 lar joints subequal ; thorax quadrate, coarsely rugose ; first abdominal segment 

 sessile, pygidium granular; pubescence sparse, the erect white hairs moderately 

 long. 



Head rounded, closely punctured, pubescence very sparse, yellowish, eyes ir- 

 regularly rounded, facetted and polished; mandibles short, stout at base, eden- 

 tate, sharply pointed, tips black; scape short, nearly glabrous, pedicel but little 

 shorter than the flagellar joints, which are all very nearly equal in length. Tho- 

 rax quadrate, longer than wide, not constricted and but little narrowed posteri- 

 orly, front angles prominent, metathorax declivous but rounded into the meso- 

 notum, its pubescence longer, dusky white ; mesonotum coarsely rugoso-punctate 

 becoming transversely rugose posteriorly ; metauotum rugoso-punctate, smooth 

 at apex ; pleurae highly polished and smooth on posterior half, anteriorly punc- 

 tate ; pubescence of thorax consisting of inconspicuous appressed whitish hairs 

 and longer though not long white marginal pile. Abdomen rather closely and 

 deeply punctate, the punctures of the second segmeut distinctly separated ; ves- 

 titure wbitish rather long at base, and on apical segments; first ventral simply 

 cariuate ; pygidium margined, finely granular. Posterior legs becoming testaceous 

 apically; hairs of posterior tibiae much finer than the spines, which themselves 

 are only moderately developed ; tibial spurs testaceous. 



Length, 4.5 mm.

One female. Feclor, Texas (Rev. G. Birkman). No date. 



This species resembles venenaria, but is readily distinguished by 



the form of the mandibles and of the pygidium. 



90. Win ilia aprica sp. nov. 



Female. Testaceous, finely punctured species, clothed with sparse, appressed 

 and erect pubescence, that of the second abdominal segment arranged in two sil- 

 very patches; head rounded, eyes oval, facetted, mandibles edentate, first flagel- 

 lar joint but little longer than the second ; thorax quadrate, metathorax abrupt, 

 crenulate laterally; first and second abdominal segments broadly sessile, pygi- 

 dium prominent. 



Testaceous, head rounded, as wide as the thorax, rather closely and finely 

 punctured, pubescence hlackish and sparse, the erect hairs cropped, angles not 

 carinate or dentate; clypeus shallowly convex, mystax long but scattered ; eyes 

 oval, rounded, facetted, dull ; antennae testaceous, scape short, punctured closely, 

 hairs almost wanting, pedicel subequal to second flagellar joint, first joint slightly 

 longer; mandibles slender, pointed, sickle-shaped, apical third black, along the 

 sides are several prominent hairs. Thorax quadrate, flattened, but little con- 

 stricted posteriorly, punctured like the head but more sparsely, pubescence sil- 

 very, short, more or less sparse and appressed, marginal hairs long, erect; meta- 

 thorax abruptly declivous, smooth and polished except where it meets the 

 mesonotum, where it is reticulate, as usual ; pleurae entirely smooth, polished. 

 Abdomen elongate, minutely punctured, first and second segments sessile, the 

 carina of the petiole slight, first and apical segments with long wbitish hairs, 

 pubescence of second segment black medially outlining two ovate patches of 

 denser silvery pubescence, apical margin fringed with silvery, pubescence of
