THE XILIMA-NJAEO EXPEDITION. 
only a very small lateral impression; the dorsal median channel well- 
marked. Elytra very strongly and irregularly punctured, with small 
punctures interspersed ; the punctures near the shoulders are somewhat 
transverse, and the interspaces being very narrow become transverse 
rugae. All the large punctures are finely punctured and filled with 
pale pubescence, which gives the elytra a speckled appearance. The 
lateral and apical costae are as in A. natalensis, but not so strongly 
marked, and there is no lateral stripe above the lateral costa. Antennae 
black, with the opaque portions smoky. Underside of the body 
somewhat violet, the abdominal segments margined with green. Legs 
coppery. 
Length 25 millim. 
Psiloptera LiETA, n. sp. (Illustrated P. Z. S. 1885, p. 235.) 
Pather parallel, depressed, bluish green above, brassy green below. 
Head very rugose. Thorax nearly one-third broader than long, a little 
broader across the middle than at the base, and then obliquely narrowed 
in front, with a shallow median impression and one on each side; 
the surface rather strongly but very irregularly punctured, coarsely 
rugulose-punctate at the sides ; the irregular space on each side of the 
median impression sparingly punctured, shining coppery ; and a little 
more removed from the middle there is an irregular-shaped coppery 
spot a little in front of the middle. Scutellum black. Elytra nearly 
parallel for two-thirds their length, then narrowed to the apex, not 
very convex, with lines of somewhat strong punctures ; the alternate 
interstices flat, the others in parts very slightly convex ; the flat inter¬ 
stices are strongly and not very closely punctured; the others have 
each about eight ovate finely punctured impressions ; the raised parts 
smooth and slightly brassy. At the sides there is a submarginal, 
closely, and finely punctured impressed line, extending from under 
the shoulder to near the apex; in this stripe there is some very fine 
whitish pubescence, which is only visible in certain lights. Proster¬ 
num with a triangular projection on each side of the front margin. 
Abdomen irregularly and strongly punctured, and finely pubescent. 
Length 30 millim. 
Molurid^. 
Melanolophus ater, n. sp. (Illustrated P. Z. S. 1885, p. 235.) 
Dull black. Head closely and strongly punctured, with a slight 
impression on the forehead. Antennas with the third joint nearly as 
long as the fourth and fifth taken together ; the fourth joint a little 
longer than broad, the following joints very similar; the tenth joint 
the same length as the ninth, but broader than long; the eleventh 
as broad as the tenth, but short, truncate at the apex. Thorax as 
long as broad, or even a trifle longer, very convex (densely and 
strongly punctured, the intervals irregular, shining, rugae or granules),
