fovcae in tlic frontal cavity and a space behind the eyes 

 excepted) testuceous, the elytra with three transversely 

 ])laeed white spots below the base — one small, common^ oil 

 the sntnre, the two others larger, triangular, external ; the 

 surface sparsely, obsoletely punctulate. Head with a multi- 

 foveate triangular excavation behind the smooth, sub- 

 triangular, concave anterior portion, the depressed inter- 

 ocular s])acc with a small prominence in the middle 

 posteriorly ; antennie long, slender, filiform. Prothorax 

 elongate, narrow, strongly constricted and transversely 

 excavate below the base. Elytra long, widened posteriorly, 

 deeply excavate below the base. Legs very slender. 



Length 2.1 mm. 



Hab. S. Africa, Dunbrody^ {O'NeU). 



There is a c^ of this species in Dr. .MarshalFs collection. 

 The elytra are marked as in the insect named by AbeiUe 

 de Perrin Cludicurus triyuttatus.

Tlie collections before me contain eight S. or E. African 

 forms agreeing very nearly with Erichson's definition of 

 Troglops; some of tliem belong to Calotroglops, Ab., which 

 was based upon four species with maculate elytra, and the 

 elytra themselves incompletely covering the abdomen in the 

 $ , characters of no importance. The insects here noticed 

 have, in the ^ sex, the anterior tarsi 4-jointed (joint 1 being 

 greatly elongated and dentate at the tip in T. donckieri, Pic) ; 

 the antennae filiform or tapering, joints 1 and 3 or 1-4 

 thickened in certain species, and 3 much longer than 2, and 

 sometimes compressed; the head large, with deep frontal 

 cavity ; the prothorax more or Itss elongate, constricted 

 tow aids the base ; and the elytra simple. The $ ? of four 

 of the S. Afiican species have been obtained, three being 

 apterous (two dimorphic) and one fully winged. The eyes 

 in (J are less prominent than in Chalicorus. Two E. African 

 Troglops have been named Ijy Pic. The Abyssinian T. mega- 

 cephalns. Roth (1851), of which there is a male in the 

 British Museum, is synonvmous with Hedybius formosus, 

 Keiche (1849) ; T. luteus, Roth = H. lividus, Gorh. (1883); 

 and 2\ signatus, Roth, is almost certainly a variety of 

 H. runbatipenni's, Pic (191 J).
