Articular surfaces of hiud tibiae very feebly or 

 not cavernous ; tips of hind tibiae with, at 



most, a double row of fimbriae ARAMIGUS. 



Articular surfaces of hind tibiae, strongly cavern- 

 ous ; tips of hind tibiae with oval scal}-^ space. PHACEPHOLIS. 

 Rostrum moderately elongate. Scrobes cavernous 

 in front. 

 Articular surfaces of hind tibiae sparsely scaly. . . ACHRASTENCJS. 

 Artipus has a form somewhat resembling Ct/phus, without however 

 having the humeri prominent. The next two genera, especially Aramigus 

 resemble an elongate Stropliosomus. Aclirastenus resembles Peritelus. 



ARTIPUS Sch. 



Artipus Schonh. Cure. Disp. Meth., p. 133. 



Rostrum not longer than the head, robust, angles rounded, finely canal- 

 iculate above, and with a very shallow impression near the apex crossed by a 

 feeble transverse ridge between the insertion of the antennae, tip triangularly 

 emarginate, and with a narrow smooth space ; genae deepl}^ notched. 

 Scrobes narrow in front and moderately deep, gradually broader and evan- 

 escent behind, the lower border strongly arciiate and directed inferiorly. 

 Eyes oval, slightly longitudinal, moderately prominent. AntenntB sub- 

 terminal, moderately long ; scape feebly clavate and attaining the thorax ; 

 funicle 7-jointed, 1-2 longer, sub-equal, 3-7 shorter sub-equal ; clul) oblong 

 oval. Thorax cylindrical, slightly narrowed in front. Sciitellum mode- 

 rate, oval. Elytra oval, nearly twice as long as wide, not wider than the 

 thorax, base sub-truncate, humeri feebly oblique. Metasternum moderately 

 long. Intercoxal process of abdomen broad, rounded at tip ; second seg- 

 ment longer than the two following, separated from the first by a strongly 

 arcuate suture. Anterior and middle tibiae mucronate. Articular surfaces 

 of hind tibiaj scalj\ Claws free. Body winged, surface densely scaly. 



Not only are the hind tibi;e scaly at tip, but also the articular surfaces of 

 the other tibiae are partial!}- encroached upon by scales, and those of the 

 hind tibiae are very feebly cavernous. 



A. floridanus, n. sp. 



Form oblong, surface densely clothed with white scales, varying to pale 

 greenish blue with cupreous lustre. Head and rostrum not as long as the 

 thorax, sparsely punctured and densely scaly. Thorax as wide as long, 

 cylindrical, slightly narrower in front, sides very slightly arcuate, apex 

 and base truncate, disc moderatel}' convex, median line moderately im- 

 pressed, interrupted, surface unevenly punctured, densely scaly. Elytra 

 nearly twice as wide as long, broadest behind the middle, sides feebly ar- 

 cuate, base sub-truncate, disc moderately convex, feebly striate, striae with 

 moderate but very unequal punctures not very closely placed, intervals 

 nearly flat, each with two rows of short scale-like hairs, surface densely 

 seal}', the larger punctures surrounded by a darker area. Body beneath 

 and legs densely scaly and sparsely hairy. Length .24 inch ; 6 mm.
