83 OTIORHYXCHID^. 



[Horn. 



Scape moderate, scrobes long, passing beneath the 



eye?. Scutellum small, triangular CYPHUS. 



Scape short, stout, scrobes short, suddenly arcu- 

 ate, Scutellum rather large, oval .BRACHYSTYLUS. 



Brachystylus has been placed by Lacordaire among the OtiorhyncMni, 

 but the entire structure is that of the Gyphini, notwithstanding the slight 

 irregularity in the form of the scrobes.

Rostrum as long as the head, slightly dilated at tip which is deeplj^ emar- 

 ginate above and at the sides, above finely sulcate and with a broad trian- 

 gular impression at apex. Supports of deciduous pieces prominent. Scrobes 

 deep, shallower behind, moderately arcuate and terminating above the in- 

 ferior edge of the eye. Eyes oval, sub-acute beneath. Antennae mode- 

 rately long, sub-apical, scape long, passing the eyas behind, feebl}^ clavate ; 

 funicle 7-jointed, joints 1-2 longer, the second longer than the first, joints 

 iJ-7 nearly cylindrical, feebly decreasing in length ; club elongate oval. 

 Thorax broader than long, narrower in front, truncate at apex, bisinuate 

 at base. Scutellum rounded. Elytra oblong, wider than the thorax, 

 humeri prominent. Anterior tibine moderately, middle tibiae feebly mucro- 

 nate ; articular surface of hind tibia; cavernous, densely scaly. Intercoxal

Form elongate, somewhat navicular, surface densely covered with scales 

 fi. varying in color from white to greenish-white. Head and rostrum longer 

 than the thorax, sparsely punctured, densely covered with scales vaiying 

 in color from white to pale cui)reous. Antennae scaly. Thorax Avider at 

 base than long, apex truncate, base bisinuate, sides moderately arcuate and 

 converging in front, disc moderately convex with broad median groove 

 wider beh.nd, limited on each side by an obtuse ridge, surface sparsely 

 punctured, densely scaly. Elytra more than twice as wide as long, slightly 

 wider behind the middle, and feebly acuminate at tip, disc moderately con- 

 vex, feebly striate, striae with large distant punctures, alternate intervals 

 Bub-costiform, surface densely scaly and with very short scale-like hairs on 

 the castiform intervals. Body beneath and legs densely scaly and with 

 short setae. Length .36-. 48 inch ; 9-12 mm. 



The color of the scales covering the body varies fi'orn white to pale 

 green. In the latter case the upper side of the head and the outer side of 

 the legs are pale cupreous.
