Description. — Black, the surface, including api)endages, consi)icuously 
marked with pale greenish granules; second antennal segment with a white 
a])ical ring of variable width; postero-lateral margins of iironotum narrowly 
pale; ajiex of scutellum broatlly and indefinitely reddish yellow; ai)ical angles 
of connexival segments and inner margins of genital lolies pale; femora and 
tibiae j)ale at ajrex; membrane whitish hyaline, with large brownish spots. 
Head almost as long as broad (20 to 21), longer than i)ronotum (20 to 18); 
tylus of moderate size, slightly enlarged at middle; impressions of vertex 
short, deep, strongly divergent anteriorly; ]U'eocular tubercles obsolescent; 
antenniferous s])ines rather short, conical, divergent, the lateral t(joth (obso- 
lescent; ])ostocular tuloercles slight; antennae (fig. ToTc) moderately stout, 
somewhat shorter than head and joronotum together (24 to 3S), the first 
segment reaching middle of tylus, second about as long as distance between 
eyes; rostrum short, extending slightly beyond apex of jorosternum. Pro- 
notum (fig. 57d) very slightly and irregularly convex, the lateral margins 
rather broadly exioanded, not reflexed, finely and rather irregularly denticu- 
late, straight or slightly concave posteriorly; carinae slightly elevated. Scu- 
tellum longer than pronotum (23 to IS), rather elongate, sides almost evenly 
arcuate from base, very slightly elevated; apex broadly rounded; discal 
elevation very slight. Ilemielytra (cf) reaching genital hrbes, corium to 
base of fourth segment, moderately narrowed, exjiosing most of connexivum 
at sides; (?) reaching base or middle of dorsal genital segment, corium to 
l)ase or nearly to ajiex of fourth, more strongly narrowed, exposing disc* of 
abdomen at sides; basal ex{)ansion of exocorium moderate, evenly rcjunded, 
moderately reflexed; mesocorium and endocf)rium with several distinct trans- 
verse veins. Abdomen rather l)roadly oval, the lateral margins crenate. 
cf (fig. .57b). Fifth ventral segment slightly shorter than sixth; genital 
segment rather short, strongly convex, the lolres long. Length, 4.5 mm. 
9 (fig. 57a). Posterior margin of dorsal genital segment transverse at 
middle, sharply sinuate at sides near spiracles. Length, 4.S to 5.2 mm.

This is a rare and very singular form, quite distinct in most 
of its characters, particularly in the shape of the pronotum. As 
\'an Duzee remarks in connection with th.e original description: 
“The short rostrum allies it with Quilnus and in some respects 
it is intermediate l)etween that subgenus and the more tyi)ical 
aradids.”
