45. Aradus (Aradusi arizonicus sp. nov. (Plate V, lig. 45.) 
Description. — Black; base of head with obliiiue pale lines; coiinexivuni 
with conspicuous yellow stripes; inner margins of genital lol)es yellowish; 
cells of corium moderately clear hyaline; membrane whitish hyaline. 
Head longer than broad (25 to 22), longer than pronotum (25 to 20); tyhis 
long, sides nearly parallel; impressions of vertex, broad, rather shallow, 
parallel, completely connected jrosteriorly; preocular tubercles very dis- 
tinct, moderately acute; antenniferous spines very short and thick, not 
reaching middle of first antennal segment, divergent, without lateral tooth; 
postocular tubercles prominent, rounded; antennae (fig. 45c) moderately 
slender, second and third segments comj)ressed, much shorter than head 
and promdum together (37 to 45); first segment scarcely reaching middle 
of tylus, second longer than distance between eyes (15 to 13); rostrum e.x- 
tending almost to middle of mesosternum. Pronotum (fig. 25d) moderately 
convex, the transverse depression obsolete; lateral margins narrowly and 
evenly expanded, moderately reflexed, finely granulate; carinae moderately 
elevated. Scutellum longer than pronotum (25 to 20), rather broadly tri- 
angular (25 to 20), sides parallel at extreme base, then slightly arcuate to tlie 
very narrowly rounded apex, strongly and sharply elevated; discal elevation 
rounded, triangular, not extending beyond middle; base depressed. Ilemiely- 
tra ( 9 ) extending to ai)ex of dorsal genital segment, corium to apex of fourth; 
e.xocorium not expanded at base; corium hyaline, with numerous transverse 
veins; endocorium without wrinkles; corium narrower than scutellum at 
level of middle of latter. 
cf. Unknown. 
9 (fig. 45a). I’osterior margin of dorsal genital segment nearly straight; 
lobes as seen from above (fig. 45e) short, posterior margin concavely arcuate; 
abdomen oval, much wider than hemielytra, the lateral margins entire. 
Length, 5.4 mm. 
Ilolotype . — 9 , Santa Rita Alouiitaiiis, Arizona, 5-8(400 feet, VI 
(F. H. Snow), in iny collection. 
This species is closely related to lugubris, but well distinguished 
by the longer head, broader scutellum, narrower hemielytra, and 
differently shaped genital lobes. The flattening of the antennae 
is probably varial)le, as in lugubris.
