ymous with Horvath’s previously published name. The species 
was first described from Holland where it was found infesting 
rhododendrons, probably as a visitor from the United States, and 
recently it has similarly occurred in England. As noted by Cham- 
pion, Heidemann’s generic reference is correct, as the lateral pro- 
notal carinae are percurrent in this species and not abbreviated as 
in Stephanitis Stal. 
Leptoypha Stal. 
The rather common misspelling, Leptophya, is perpetuated by 
Osborn and Drake on page 241 of their first paper. In their generic 
diagnosis it is the posterior “tip” of the rostral sulcus which is 
described as open, though in reality it is nearly or quite closed by 
the convergent ends of the metasternal ridges. In L. mutica Say 
the head is provided with five spines as in related forms. 
The chief characters separating Leptoypha from closely allied 
genera may be stated as follows: Entire surface very finely and 
evenly reticulate; antenne short, cylindrical, the third segment not 
greatly longer than the others together; hood absent; lateral carinze 
absent or vestigial; paranota linear, cariniform; costal area linear 
or narrow and uniseriate; subcostal area with 4-6 rows of areoles. 
Leptoypha costata sp. nov. 
Long-winged form.—Brown, shining, evenly and finely reticu- 
late; more or less variegated with vague darker markings; prono- 
tum with a black transverse suture interrupted at middle; body 
beneath chestnut brown, sternal region infuscated. 
Head broad; vertex punctate at middle; basal spines short, reach- 
ing base of anterior spines, which are short and curved with apices 
meeting that of median spine; antenniferous tubercles moderate 
in size, oblique, rounded exteriorly; antennz short, cylindrical, 
minutely pubescent, first and second segments nearly equal, slightly 
longer than broad, thickest, third slightly more slender, cylindrical, 
a little less than twice as long as the first two together, fourth some- 
what longer than the first, fusiform. Pronotum convex at middle, 
narrowed anteriorly, depressed behind the narrow raised apical 
collar; median carina slightly raised but appreciably percurrent; 
lateral carinz parallel, exceedingly faint, beginning just anterior 
to summit of pronotal convexity and extending to margins of angu-
