four tubercles across middle, the median ones much larger 

 than the outer ones, and semi-double ; subapical constriction 

 deep and irregular, at median carina suddenly deflected back- 

 wards to tubercle ; elsewhere with deep and more or less 

 curved grooves; median carina very distinct, somewhat de- 

 pressed at apical third. ScuteUuin absent. Elytra elongate- 

 ovate; with rows of large deep punctures, larger on sides 

 than elsewhere ; second interstice with an elongated fascicular 

 crest, near base, about middle, and at summit of posterior 

 declivity supported by distinct tubercles; fourth interstice 

 with two moderately large and two small fasciculate tubercles, 

 a few feeble ones elsewhere. Mesosternal receptacle fairly 

 large and strongly raised; emargination widely transverse. 

 Abdomen with dense more or less concealed punctures; first 

 segment not as long as three following combined and scarcely 

 longer than fifth; second, third, and fourth of almost even 

 lengths, their sutures deep. Legs long and thin; hind femora 

 just passing apex of elytra ; third tarsal joint slightly nar- 

 rower than second and not deeply bilobed. Length, 

 15J-20 mm. 



9 . Differs in being somewhat stouter, in having the 

 rostrum considerably longer and somewhat thinner, with its 

 sides not inflated near base, antennae inserted less close to apex 

 of rostrum, and legs a trifle shorter.

A large species, close to carinicoUis but with median pro- 

 thoracic carina not overhanging the scutellar region, the 

 tarsi with denser clothing and truly linear (^D and without 

 a conspicuous lateral tubercle near shoulder when viewed from 

 above. JRuhus has more numerous tubercles, is without 

 elongated fascicles on the posterior declivity, and has small 

 conical apical tubercles. Interniedius and idolus have con- 

 joined tubercles at summit of posterior declivity, different 

 tarsi, etc. The scales composing the fascicles are usually, but 

 not always, darker than the adjacent ones. As with many 

 others of the genus, the whole of the derm, on the spaces 

 between the scales, is closely covered with minute black scales 

 (invisible except on a close examination), giving the surface 

 a somewhat shagreened appearance. 



One large specimen differs from the others in having the 

 individual scales much shorter, so that the tubercles and

 institution) and in Mr. C. Frenchs collection from the Endeavour 

 River. 



(31) It would thus be a Mormosintes, if the linear tarsi were to 

 be regarded as of generic importance.
