is S. gracilis Shp. The latter is 5 mm. in length, the former 
not much shorter but notably more slender. 
DOLICAONES. 
This subtribe combines in a remarkable manner the essential 
characters of the Paederi and Lathrobia, agreeing with the 
former in the general nature of the male sexual characters 
and in the peculiar compressed and pubescent fourth joint of 
the maxillary palpi, and with the latter in general habitus, 
structure of the prothorax and other features. The genera 
are few in number and belong wholly to the old world fauna 
in all probability. Those represented in my cabinet may be 
defined as follows : —

2— Body very large, rather stout and parallel, moderately convex, coarsely, 
rather sparsely punctate, the pronotum with only a partially defined 
median smooth line, the abdomen with coarse sparse punctulation; hairs 
long and bristling; head large, oblong, the neck very broad, nearly 
three-fourths as wide as the head; labrum short and transverse, with 
a small triangular emargination, at each side of which there are two 
very short obtuse denticuliform lobes; antennae filiform, rather stout, 
barely as long as the head, the joints feebly obconical, the basal joint 
cylindric, but little longer than the next two combined; gular sutures 
feeble, rather narrowly separated, gradually converging and most 
approximate behind the middle, rapidly diverging and obsolescent at 
base; ligula bilobed at tip; paraglossae compressed, fimbriate at tip; 
maxillary palpi moderate in length, rather slender, coarsely, sparsely 
setulose; prothorax large, oblong; prosternum short before the coxae; 
elytra very short, less than half as long as the prothorax, with rounded 
basal angles, the hind wings probably wanting or vestigial; abdominal 
segments only very feebly impressed at base; legs rather long, some- 
what slender; hind tarsi nearly three-fourths as long as the tibiae, 
densely clothed with stiff fulvous hairs beneath, the first joint much 
longer than the second and subequal to the fifth; claws moderate; 
anterior tarsi moderately dilated. South Africa. [= Ophiomorphus
