238 FAMILY VI. — COREIDjE. 



State. Of it Van Duzee (loc. cit.) says: "This large showy- 

 insect seems to be strictly intermediate between dorsalis White 

 and gundlachi Guer. From the former it differs most conspicu- 

 ously by the alternated connexivum and from the latter by 

 the unicolorous corium." 



Tribe VI. CHARIESTERINI Stal, 1867, 546. 



Slender elongate species having the head short, quadrate ; 

 antenniferous tubercles prominent, spined above, the spines 

 oblique, acute on inner side ; antennae with first joint stout, 

 feebly curved, usually thickened toward apex, third joint 

 widely dilated ; pronotum with humeri prominent, spinose ; hind 

 coxae separated by a space more narrow than that between 

 them and sides ; femora all armed beneath near apex with a 

 short spine; tibiae slender, simple. The tribe comprises three 

 genera, two confined to tropical America, the other represented 

 in the United States. 



I. Chariesterus Laporte, 1832, 44. 



Elongate slender-bodied species possessing the characters of 

 the tribe and having the head without a tubercle behind the 

 eyes; antenniferous tubercles subcontiguous, their spines con- 

 verging, obliquely truncate and acuminate; first joint of anten- 

 na? of nearly equal thickness throughout, somewhat three- 

 sided, the edges of basal half dentate; beak reaching middle 

 coxae, its joints subequal, the basal one stoutest ; bucculae short, 

 wide, subtriangular ; pronotum with front margin not im- 

 pressed behind to form a collar, its side margins dentate and 

 humeri with short spine ; membrane reaching tip of abdomen, 

 its veins rather few, forked and irregularly anastomosing; 

 connexivum narrowly exposed ; meso- and metasterna rather 

 deeply sulcate ; genital plate of male scoop-shaped. 



Six species are known, three from the United States, one of 

 which occurs in our territory. 



172 (283). Chariesterus antennator (Fabricius), 1803, 198. 



Elongate, slender, depressed above, subconvex beneath. Dark brown, 

 thinly clothed with short appressed brownish-yellow hairs, in fresh 

 specimens more densely beneath with a whitish bloom; dilation of third 

 antennal, spines along edges of pronotum, margins of abdomen, beak 

 and tarsi, fuscous. Antennae with basal joint twice or more the length 

 of head, second one-third shorter, third with apical half dilated to
