Among the interesting species of Heteroptera which have been sent 

 to the Division of Entomology by correspondents during the present 

 season was a species of Tingitidae which has not hitherto been described. 

 In accordance with an estabhshed custom of the U. S. Department of 

 Agriculture, the following description is submitted for publication in a 

 periodical journal in preference to publishing it in a Departmental bulletin.

 yellowish-white, translucent; body black beneath; posterior part of the 

 rostral groove at the metasternum transverse. Head black, with three 

 white, short but rather thick, obtuse spines in front between the antenna. 

 Antennae slender, finely ciliated, testaceous, apical joint blackish ; basal 

 joint nearly twice as long as joint two ; joint three very long, about four 

 times as long as the apical. Pronotum dark, with three carinje ; the 

 interspaces closely and finely punctate ; the carinse moderately foliaceous, 

 testaceous, the median carina posteriorly whitish, tapering toward the apex 

 of the reticulated membranous triangular portion of the pronotum ; the 

 membranous pronotal margin raised and moderately wide, angularly dilated 

 behind the middle, with tv.'o rows of areoles at the narrow portion and 

 with three areoles at the widest pari, the areoles infuscated ; j^ronotal 

 hood small, oblong, somewhat compressed, with a sharp carina at the top, 

 slightly projecting in front, leaving the eyes free; the hood, the three 

 carinse and the edge of the pronotal margin densely fringed with long, soft 

 hairs. Hemelytra extending far beyond the abdomen, oblong-oval, 

 broadly rounded at the apex, the sides abruptly converging to the base ; 

 subcostal and discoidal areas closely reticulated, the subcostal biseriate, 

 the discoidal area comparatively narrow and not reaching the middle of 

 the hemelytra, with three series of areoles at the widest part ; the costal 



area rather broad, the areoles of irregular size, more or less hexagonal, 

 except those along the exterior margin, which are either pentagonal or 

 quadrate ; the sutural area, but not the inner basal portion of it, has a few 

 quite large areoles ; three or four oblitpie blackish nervures at the costal 

 area, and also some slightly darkened nervures at the apex of the
