oculos bispinoso; rostro nigro; antennis ferrugineis, clava fusca; pro- 
thorace niveo, basi fusco-squamoso, dorso medio elevato, quadri- 
cristato; elytris fusco-squamosis, humeris brunneis, plaga magna re- 
gione scutellari niveo-squamosa; corpore subtus pedibusque totis

Hab, Natal. 
Isax. 
Rostrum truncatum, rectum, basi omnino cylindricum; scrobe recta, 
oculum tingente. Ocul rotundi, subfrontales, distantes. Antenne ante 
medium insertz; scapo subbrevi; funiculo septem-articulato, articulis 
duobus basalibus elongatis; clava modice ovata. Prothorax latus, 
antice valde constrictus, lateraliter rotundatus, basi rectus. Scutellum 
suborbiculare. Elytra breviter ovata, humeris paulo productis. Pedes 
breviusculi, crassi, antice vix majores; ¢ibie@ uncinate ; tars? equales, 
breves, triangulares, articulo ultimo elongato; wngues distincti. Meta- 
sternum nonnihil elongatum, -dbdomen segmentis duobus basalibus 
majoribus, liberis. Processus interfemoralis apice rotundatus. 
The slender, straight, almost perfectly cylindrical rostrum at the 
base will distinguish this genus from most of the Cryptorhynchine, 
at least such as belong to the Australian fauna. 
Isax gallinago. (Pl. XVII. fig. 14.) 
I, elliptico-ovatus, niger, opacus, squamis griseo-brunneis dispersis ; 
rostro nitido, punctato; antennis ferrugineis, nitidis; clava fusca; 
prothorace medio leviter excavato, confuse punctato, lateribus vage 
punctato, utrinque tuberculis squamigeris tribus vix elevatis, quorum 
uno apice, sito; scutello elevato; elytris substriato-punctatis, punctis 
foveolatis, singulis tuberculis squamigeris oblongis, vix elevatis, quinque, 
scil, 3 externis, 2 internis : humeris haud projectis, apice conjunctim ro- 
tundatis ; corpore subtus nigro, parce squamoso, pedibus densius griseo- 
squamosis. Long. 43 lin. 
Hab. Queensland. 
MormosintEs. 
Characteres generaliter ut in Poroptero, sed articulo ultimo funiculi clave 
adpresso ; ¢arsts linearibus, articulo penultimo integro ; processu inter- 
femorali antice angulato. 
These characters will distinguish this genus from Poropterus. It 
has much the habit of P. Parryi, Waterh., but is larger and less 
scaly. The lines separating the abdominal segments are very deep 
and decided. 
Mormosintes rubus. (Pl. XVII. fig. 15.) 
M. niger, squamis ferrugineis minutis parce dispersis; rostro reticulato- 
punctato; prothorace antice constricto, bituberculato, in medio carinato,
