and narrower, more parallel prothorax. The eyes are more nearly contiguous 
above *. 
g. Cnesinus elegans, sp. n. (Tab. VI. fig. 11.) 
Linearis, subnitidus, piceus, elytris ad basin dilutioribus ; prothorace haud transverso, rimose punctato; elytris 
ad apicem fortiter convexe declivibus et in medio impressis, tenuiter striato-punctatis, interstitiis planis 
subtiliter punctato-rugosis postice seriatim setosis. 
Long. 2°7 millim. 
Elongate, subparallel, somewhat shining. Head black, scarcely rostrate, impressed and pilose over mouth ; 
front shining, with setigerous punctures at sides, vertex punctured; eyes large, contiguous above, 
coarsely granulate. Prothorax as long as broad, widest in the middle, basal angles rectangular, 
sides straight and divergent to the middle, thence obliquely rounded to apex and subconstricted ; 
surface moderately convex, deep piceous with apex ferruginous,|thinly pubescent on the anterior margin, 
covered with longitudinal but scarcely strigose punctures, denser towards apex and on either side of a 
median subelevated line, interspaces not elevated, shining, in parts with traces of reticulation and finer 
punctures. Scutellum piceous-black, rounded, punctured. Elytra a little more than twice as long as the 
prothorax and wider at the base, with the margins not strongly rounded nor elevated, shoulders prominent, 
sides subparallel, apex circularly rounded ; surface subcylindrical, convexly declivous at apex, which is 
impressed in the middle, piceous-brown, posteriorly darker, finely striate-punctate, the three inner strize 
alone impressed throughout, the punctures very finely setigerous on the declivity, interstices flat, finely 
multipunctate, rugose at base, subconvex on the declivity, bearing each a row of stronger setz, beginning 
on the two inner interstices as far forward asthe middle. Underside piceous, punctured ; abdomen thinly 
pubescent. Legs pitchy-brown ; intermediate tibiee with upper apical angle not produced.

Described from six specimens. This species is more elongate and shining than 
C. strigicollis, Lec.; the prothorax is less densely punctured, and the punctures are 
less strigose; the elytral interstices are shining and nearly smooth. 
The specimens, as with C. strigicollis, show slight individual peculiarities which 
may or may not indicate sexual or specific differences; but the examples here grouped 
for description form a fairly well-defined aggregate. 
* In an arrangement of the genus, the following species may be placed next C. setulosus :— 
Cnesinus ocularis, sp. n. 
Elongatus, piceus, elytris brunneis, pedibus rufescentibus, vel totus fusco-ferrugineus ; oculis magnis in fronte 
contiguis ; prothorace latitudine vix longiore, conferte strigoso-punctato, linea media angusta elevata, 
parce pallide piloso ; elytris anguste punctato-striatis, interstitiis planis, subtiliter rugulosis, uniseriatim 
setosis, declivitate vix impressa. 
Long. 2°4 millim. 
About the size of C. strigicollis, but much slenderer, intermediate in shape between it and C. elegans. The 
colour, when mature, similar to that of the former species. Eyes very large, approximate above; frontal 
pubescence similar but thinner, vertex dull. Prothorax narrower and relatively longer, more parallel- 
sided behind, the pubescence stouter and more conspicuous. Elytra with narrow punctured strive, the 
interstices finely wrinkled, without elevated ruge, with single series throughout of strong suberect pale 
pristles, rather longer behind, the decumbent hairs scarcely visible without the microscope ; declivity very 
slightly impressed in the middle.
