NOTE ON THE CUECULIONID - GENUS STSCIOPHTHALMUS Heller, 



WITH A DESCRIPTION OF A NEW SPECIES FRON TIERRA 



DEL FUEGO. 



BY G. C. CHAMPIOX, F.Z.S. 



In the "Stettiner entomologische Zeitung" for 1906 Dr. K. M. 

 Heller described and figured both sexes of a remarkable new Tanymecid- 

 weevil from Santa Cruz, Argentina [Patagonia], under the name St/s- 

 ciophtlialmus hruchi. Four specimens (3 $ $ , 1 c? ) of this insect were 

 acquired b}^ the British Museum in 1903, all from the Valle del Lago 

 Blanco, Patagonia (Koslowski/), as well as a second species of the same 

 genus from Useless Bay, Tierra del Fuego, in 1906. The eyes in the 

 present genus are large and fineh'' facetted, and placed beneath 

 the rounded, lateral, ear-like expansions of the head, and completely 

 invisible from above, and the vibrissae are long and numerous. 

 Si/sciophthalmus is an addition to Enderlein's list (1912) of the Coleo- 

 j)tera of Tierra del Fuego. It is related to Anaemerus Schonh., from 

 Africa and Madagascar. 



SysciophtlialmMS crawsliayi, n. sp. 



J . Moderatel}'^ elongate, black, opaque, densely clothed with small, pale 

 greyi^4h, agg-lutinated, earthy-looking scales, variegated (the legs included) with 

 whitish and velvety-black scales, the latter condensed on the elytra into a 

 series of short oblique strealvs along the suture and interrupted series of small 

 spots on the disc, the whitish scales on the prothorax tending to form three 

 faint hues on the disc, the median one continued on to the base of the suture ; 

 the surface also bearing ver}^ short, stiff, decumbent hairs (densely granulato- 

 punctuhite, when the vestiture is removed). Head with large, ear-like lateral 

 processes, irregularly biseriato-tuberculate between them, appearing sulcate 

 down the middle, the rostrum very broad, the two processes at the apex 

 divergent and obliquely truncated at the tip; antennae short, the funiculus 

 5-jointed, joint 5 broader and stouter than 4, 6 and 7 apparently absorbed into 

 the ovate club. Prothorax about as long as broad, trapezoidal, slightly wider 

 than the head, feebly compressed at the base, interruptedh' sexcostate. Elytra 

 oval, not ver}- much longer than the head and prothorax united, flattened and 

 irregularly tuberculate on the disc, with interrupted series of coarse scattered 

 punctures partly hidden by the vestiture, the fifth interstice produced into a 

 Ci)nspicuous, angular, dentiform prominence at its point of termination, and the 

 apices into a stout blunt tooth, the humeri broadly, obliquely truncate, the base 

 sinuato-emarginate. 



Length b\, breadth 2j mm. 



Hah. TiERKA DEL FuEGO, Useless Bay {R. Cmicshay). 



One male, captured in Sept. 1904. Much smaller and less elongate 

 than S. hruchi^ the prothorax without projecting tubercles at the sides, 

 simph^ trapezoidal, the elytra oval and much shorter, the funiculus 

 5- (instead of 7-) jointed, the two missing joints doubtless merged into 

 the club.
