362 APPENDIX. 
Hyponieles rttgosiis, Fabricius, etc. Numerous smaller species of 
Melasomatous Heteromera, and HelopiDjE, were also taken, as 
well as ten species of Mylabrid^. 
Family Helopid^. 
Amongst the HELOPlDiE, apparently allied to Centroniptis and 
Stenochia, is an insect captured by Mr. Gates, which must be referred 
to a new Genus, 
Genus Derosph^rius, Westw. 
Corpus oblongum, subcylindricum ; capite parvo, conico,ante oculos 
utrinque rotundato - elevato, antennis longitudine dimidii corporis, 
articulis aequalibus, externis pauUo brevioribus at non crassioribus ; 
mandibulis capitis longitudine tequalibus curvatis, supra prope basim 
cornu erecto, apice inciso, armatis ; labro subrotundato, antice emar- 
ginato ; palpis maxillaribus elongatis, articulo ultimo vix securiformi ; 
mentum transversum antice angustatum ; palpis labialibus parvis, sub- 
cylindricis ; prothorax rotundatus, subglobosus ; pedes satis graciles ; 
tarsis heteromeris, simplicibus, unguibus simplicibus. 
Derosph^rius anthracinus, Westw. (Plate G, fig. 3, and 
Plate H, figs. 2, 2a, 2b, 2c.) 
Niger nitidus, capite inter antennas biimpresso, pronoto subtiHter 
punctatissimo ; elytris punctato-striatis. Long. corp. fere lin. 6. 
Family CURCULIONID^. 
Of the still more extensive family of the Weevils (Genus CtircicUo, 
Linnaeus), of which, including the Scolytid^, Brenthid^, and 
AnthribiDjE, not fewer than 1200 species have been described, large 
numbers are peculiarly African, especially the great Genera Bracliy- 
ceriis, Episiis, Microcertis, Platy copes, Sciobius, and many others, the 
species of most of which are distinguished by their dull colours and 
sluggish movements, fitting them for their existence in wide arid sandy 
districts, where they emulate the PivielicE and Mohtrides. Of this 
great tribe only nine species were captured, including numbers of 
individuals of the gigantic Brachyce7'iis apteriis, remarkable for the red 
spots on its black body, B. congesttis, etc. 
Family CERAMBYClDiE. 
Of the great family of Longicorn beetles {Cej^ambyx, Linnaeus), 
consisting of not less than 8000 already described species, there are in 
South Africa 262 genera, of which no less than 67 are peculiar, namely 
5 of Prionid^, 25 of Cerambycid^, and yj of Lamiid^. The 
most conspicuous of these genera are Stet'iiotomis, Zographus, 
Alphitopola, Tragocephabis, Phryiieta, Ceroplesis. The giant Prio- 
nides are evidently very rare, but the remarkable genera may be 
mentioned, Cacoscelis, Cantharodenns, and Cantharoplaty;, Westw.
