18 Rev. H. 8. Gorham’s descriptions of 
middle, very evenly ovate, and fairly convex. Antenne 
longer than the head and thorax, everywhere with longish 
setee, of the same colour as the body, excepting the club 
alone, which is black.

Genus STENOTARSUS. 
Stenotarsus macroceras, N. sp. 
Oblongus, ferrugineus, purpureo-pubescens, antennis 
nigris, corporis fere longitudine, articulis tribus primis 
rufis, thorace elytris multo angustiore, angulis posticis 
acutis. Long. lin. 4—43, ¢, ¢. 
Head and thorax clothed with greyish-yellow pubescence, 
the latter at the base about twice as wide as long; hind 
angles acute and turned outwards, sides above the base 
nearly straight, narrowed to the apex, a little rounded in 
to the apical angles, which are not very prominent; lateral 
margins flat, rather wider at the hind angle; a short 
finely-impressed line represents the basal sulcus, which is 
only visible in rubbed specimens. LElytra at the base half 
as wide again as thorax, of a rich brick-red, with a very 
short velvet pubescence, which reflects a coppery-red light ; 
sides a little widened to the middle, thence evenly rounded 
to the apex: fully twice as long as wide, humeral callus 
well marked, ridge-shaped. Antenne black, three basal 
joints clear red, very long ; in the smaller specimens of the 
length of the whole body, in the larger, three-quarters of 
its length; joints 3, 4 and 8 equal in length; 5,6, 7 longer 
than these and nearly equal to the first joint of the club (9); 
9 and 10 elongate, sub-cyathiform, acuminate internally ; 
11 compressed, oval-elongate. Legs thin and long, clear 
red. 
Obs.—This curious species is evidently allied to S. 
purpuratus, Gerst., but is still more abnormal among the 
Stenotarst than that species; the great length of the 
antennze and small thorax reminds one of Homoiotelus 
among the Krotylide. 
Compared with S. purpuratus, the antenne have the 
joints before the club much longer and thorax wider at 
the base and more narrowed in front.
