iiifi over anterior fourth of mesostermiin. Pronotiini tfifi. 3S(1) moderately 
eonve.x, the lateral margins moderately expanded and but slight h' reflexed, 
with minute and regular granulation; earinae strongly elevated. Seufcdlum 
mueh longer than ))ronotum (40 to 2S), elongate.-eordate, sides strongly 
sinuate and well elevated except at narrowly roundetl aj^ex; disc with very 
low rf)unded elevation before middle, lleinielytra broad, scarcely exposing 
whole width of connexivum at most, (cf ) attaining ai)ex of abdomen, coriurn 
to base of fifth segment; ( 9 ) reaching base of genital lobes, coriurn to middle 
or almost to apex of fourth; b.a.sal expansion of exocorium moderate, rather 
long, reflexed; mesocorium and endocorium with several moih'rately distinct 
transverse veins; abdomen ovate, widest behind middle. 
cf (fig. 3.Sb). Fifth ventral segment slightly shorter than sixth; geiutal 
segment rather short, moderately convex, carinate. Length, (i.b mm. 
9 (fig. 38a). l)of.sal genital segment jieculiar (fig. .3Se). Length, 7.4 to 
8 mm.

This is a boreal species of rare occurrence, well distinguished 
by structure of the ])ronotum, scutellum, .and female gtaiiltditi. 
Heidemann’s figure gives its general appearance very wtdl. 
39. Aradus (Aradus insignitus sp. nov. (Plate IV, fig. 39.) 
Description. — Black; the third antennal segment bright orange yellow. 
Similar in structure to uniformis, except as follows: Tylus long, strongly 
compressed, slightly enlarged at middle; preocular tubercles slightly de- 
velojxHl, obtuse; antenniferous spines short, stout; antennae (fig. 39c) .as 
thick as front femora, the first segment scarcely reaching middle of tylus, 
length of secoiifl almost equal to wiflth of head including one eye (17 to 19). 
Pronotiim (fig. 39d) distinctly convex, the lateral Tuargins slightly expanded 
and strongly reflexed; earinae well elevated. Scutellum obscured. Ihani- 
elytra obscured, apparently reaching almost to ai)ex of .abdomen; basal ex- 
pansion of exocorium slight. 
cf. Unknown. 
9 (fig. 39a). Dorsal genital segment obscured; abdomen broadly oval, 
the lateral margins almost entire. Length, mm. 
Ilolotype . — 9; Massachusetts (F. CL Sanborn), in my collec- 
tion. 
This species is founded on a single damagetl specimen whicli 
has been repaired with gum so clumsily as to obscure the scuttdlum 
and hemielytra almost entirely, but the antimnal, ])ronot:d, and 
genital charactei'istics are so distinctive that then* can lx* no 
possibility of confusing it with iinifoniiis, its nearest ally.
