92 OTIORHYNCHID^. [Horn. 



Articular surfaces of hiiid tibiae very feebly or 

 not cavernous ; tips of hind tibisB with, at 



most, a double row of fimbriae AR AMI GITS. 



Articular surfaces of hind tibiae, strongly cavern- 

 ous ; tips of hind tibiae with oval scalj^ space. PHACEPHOLIS. 

 Rostrum moderately elongate. Scrobes cavernous 

 in front. 

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

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

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

 resemble an elongate Stropliosomus. AcTirastenus 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 antenn*, tip triangularly 

 emarginate, and with a narrow smooth space ; gente deeply notched. 

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

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

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

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

 funicle 7-jointed, 1-3 longer, sub-equal, 8-7 shorter sub- equal ; club oblong 

 oval. Thorax cylindrical, slightly narrowed in front. Scutellum 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 tibiie mucronate. Articular surfaces 

 of hind tibiae scaly. Claws free. Body winged, surface densely scaly. 



Not only are the hind tibiae scaly at tip, but also the articular surfaces of 

 the other tibiae are partially encroached upon by scales, and those of the 

 hind tibiae are very feebly cavernous. 



A. fioi'idanus, 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 moderately 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, surfiicc densely 

 scaly, the larger punctures surrounded by a darker area. Body beneath 

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