except apex, tegulae, tour anterior tibiae on 

 outer side, the hind tibiae on outer side 

 except apical portion, yellowish; tarsi and 

 apical margins of the abdominal segments 

 testaceous; wings hyaline, iridescent; ner- 

 vures testaceous ; apical abdominal segment 

 more or less rufous ; head, thorax and abdo- 

 men more or less covered with silvery pile, 

 which is most dense on the face, clypeus, 

 mesopleurae and metathorax. Length 5-6 

 m m . 



Var. legs, except anterior tibiae, entirely 

 black. 



$. Anterior margin of clypeus slightly 

 produced medially; antennae shorter than in 

 the $ and sub-clavate ; clypeus entirely, 

 scape beneath, tegulae, tubercles, apex of 

 femora, the tibiae, except inner side of two 

 anterior pair, and the tarsi, bright yellow.

Niteliopsis plenoculoides. $. — Clypeus 

 strongly carinated down the middle; front 

 finely granulated, distinctly impressed down 

 the middle, along the inner eye margins the 

 front is finely punctured; eyes strongly con- 

 verging to the top, the space between them 

 at the vertex is about equal to one-half of the 

 space at the clypeus; ocelli in a triangle, the 

 lower one situated a little further away from 

 the hind pair, than the latter are from 

 each other; from each hind ocellus there ex- 

 tends down a short furrow, which readies a 

 little beyond the fore ocellus; antennae tol- 

 erably long, reaching to about the tegulae, 

 the flagellum tapering on apical half; joints 2 

 and 3 of the flagellum longest, the first and 

 fourth about equal; dorsulum with exceed- 

 ingly close and fine punctures; metathorax 

 above and on the sides finely granulated, 

 with indistinct striations when viewed in 

 certain positions ; at the extreme base of upper 

 surface there is a transverse series of small 

 fovea and down the middle there is an im- 



pressed line (this is not distinct in one spec- 

 imen), the posterior face transversely rugose; 

 tibiae and tarsi, with exception of the calcaria 

 unarmed; tarsal claws rather short, stout and 

 not toothed; abdomen elongate-ovate, the 

 first three dorsal segments when viewed from 

 the side are seen to be contracted basally and 

 apicallv; last dorsal segment without a 

 pygidium; three submarginal cells, the sec- 

 ond petiokited. receiving both recurrent ner- 

 vures ; black; two transverse spots on the 

 collar above, posterior half of tubercle-, a 

 spot near the middle of hind tibiae and the 

 tibial spurs, whitish ; apex of mandibles, 

 tegulae and tarsi, testaceous ; wings subh va- 

 line; nervures black; face and clypeus, sides 

 of thorax and abdomen, more or less, with 

 silvery pile. Length, 6 mm. 



New York: Colorado. In general appear- 

 ance this species re?embles Plenoculus davisi* 

 but the abdomen is differently shaped, the 

 antennae are longer, the legs without spines, 

 the second submarginal cell receiving both 

 recurrent nervures and the last dorsal 

 ment lacks a pygidial area. It seems to me 

 that Kohl has erred in uniting Niteliopsis 

 Saund., with Solierella Spin.* A compar- 

 ison of the figures of these genera. t is. I 

 think, evidence enough that they are not the 

 same; while ihe species herein described 

 agrees with the description and tolerably 

 well with figure of Niteliopsis it does not 

 agree with Kohl's description, nor Spinola's 

 figure of Solierella. As nothing definite 

 can be ascertained to show whether these 

 genera are synonomous or not without an 

 examination of Saunders's type, it seems 

 best for the present to consider them distinct. 

 But one other species of Niteliopsis is known 

 and is from the Ionian Islands. The si 

 species of Solierella inhabits Chili.
