tunatein view of the lack of any real affinity with Scopaeus, — 

 is S. gracilis Shp. The latter is 5 mm. in length, the former 

 not much shorter but notablv 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 : — 



Eyes normal and well developed 2 



Eyes wanting, replaced by a small whitish translucent point at the 

 posterior margin of the antennal cavity 3 



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 wa.ntiDg 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 

 Dej. and Adelobium Nord.] *Dolicaon 



Body small in size, subparallel and slender, moderately convex, rather 

 finely, sparsely and evenly punctate, the pronotum with a smooth 

 median line; abdomen not densely punctulate; pubescence short and 

 inconspicuous; head moderate, usually narrower than the pro-
