220 PERCY SLADEN TRUST EXPEDITION 
suture and ist stria, which is darker; laterally the testaceous colour extends along 
the side of the elytron between the black band and the side margin, joiming in front 
with the outer extremity of the basal reddish area, but not quite reaching the humeral 
angle, which is darker. Legs and feet reddish-testaceous. 
Head and pronotum finely and rather closely punctate, the pronotum with anterior 
and posterior angles obtuse, the latter very widely so: the fine posterior margin of 
the pronotum is seen under a high power to be interrupted by punctures. Sceutellum 
minute, rather narrow, acute at apex, with a few punctures. Hlytra with 10 punctate 
strie, the punctures larger and nearer together near the base, separated by several 
times their own diameter behind; stria 1 (the sutural) and strie 2—5 reach nearly 
to the base; stria 6 ends in front further from the base; striz 7—9 end in front 
about + the length of the elytron from the base (the 7th being just traceable further 
forward by a few punctures); stria 10 reaches about as far forward as 6: there is a 
slight callosity at the base just outside the anterior extremity of the 5th, and im front 
of that of the 6th, stria. Behind, the 10th (outermost) stria ends at about the middle 
of the elytron; 9 and 8 can be traced, running parallel to the outer margin, right 
round the apex to the suture, and they thereby prevent strie 1—5 from reaching 
the apex, while 6 and 7 are abbreviated some way further forward. The intervals 
are scarcely convex near the base, but moderately convex behind; they bear very 
fine widely-separated punctures, much smaller and finer than those on the striz. 
Under a very high power the subopacity of the general surface of the elytra is seen 
to be due to the presence of an excessively fine, minute, and close dotting. 
This may well be a new species. I have found nothing agreeing with it in any 
of the collections in the British Museum. Monsieur d’Orchymont suggested that it 
might possibly be allied closely to crenulatus Régimbart (India, Java, &¢.) or crenato- 
striatus Régimbart (Mauritius); but Monsieur Lesne, to whom I submitted it, informs 
me that both those species are much larger and differently sculptured. As I have 
only a single specimen, and have been unable to see a number of species, I have 
thought it best to describe but not to name it.

PaROOsTERNUM, gen. nov. (Plate 14, fig. 22). 
Oosterno peraftine, sed differt in forma sternorum. Pars media prosterni haud 
carinata, sed tabulam oblongam marginatam, superficie fere plana (perparum concava) 
formans. Mesosternum (ut in Oosterno) aream ovatam elevatam formans. Meta- 
sternum in medio valde elevatum, sed impressione longitudinali distincta in medio partis 
elevatz: lineis femoralibus ad angulos anteriores continuatis. 
Body somewhat elongate-oval, moderately convex, with lateral margins of thorax 
and elytra not in the least explanate; above shining, with very scanty fine hairs on 
the elytra; beneath, central part of metasternum shining, its sides and the abdominal 
segments subopaque and bearing fine short pubescence. Head deflexed in front, 
labrum hidden. Antenne 9-jointed: basal joint elongate, longer than joints 2—6
