about one-fourth from base of rostrum, third joint about the 

 length of first, distinctly longer than fourth, and fully twice 

 the length of second, eleventh about once and one-fourth the 

 length of tenth. Prothorax about as long as greatest width, 

 sides strongly rounded, base not much wider than atpex, 

 median line lightly impressed; densely granulate. Elytra very 

 thin, slightly wider than prothorax, parallel-sided to near 

 apex, which is lightly produced, suture not elevated at base; 

 densely punctate. Femora edentate, hind ones slightly passing 

 apex of basal segment of abdomen; basal joint of tarsi as long 

 as second and third combined. Length, 7-9 mm.

The clothing has a peculiarly loose flocculent appearance 

 along the suture, which readily distinguishes the species from 

 variabilis, the rostrum is also thinner and antennae longer 

 than on that species; the clothing is very different to that of 

 lo7igicornix and filiformis, with which it would be associated 

 in my table ; in many respects it is close to acacia e, but the 

 front femora are edentate ; from parallelus it differs in having 

 looser clothing, abdomen with nude spots only on sides, and 

 rostrum, antennae, and basal joint of tarsi longer. The sexes 

 differ in the width of prothorax and thickness of front femora. 

 The rostrum (either entirely or with the base excepted) is of a 

 brighter red than the other parts. The pubescence margins 

 the eyes, but is sparse on the upper parts of the head, on the 

 pronotum it forms a fairly distinct median line, but is dense 

 on the sides, is dense on the scutellum, on the elytra it forms 

 loosely compacted spots along the suture, and smaller and still 

 looser ones elsewhere, with a few hairs scattered singly; on 

 the under-surface it is dense, but somewhat sparser along the 

 middle than on the sides; the metasternal episterna are 

 uniformly clothed, but there is a fairly large nude spot on 

 each side of each of the four basal segments of abdomen. 



BELUS TRIL1NEALBUS, n. sp. 



Black ; rostrum, base of head, and parts of antennae and 

 of legs more or less reddish. Clothed with white pubescence, 

 mostly maculate in arrangement. 



Head coarsely sculptured between eyes, less coarsely at 

 base. Rostrum long, thin, and distinctly curved; behind 

 antennae with rather coarse punctures, in front with smaller 

 but quite conspicuous ones. Antennae moderately long, first 

 joint about as long as second and third combined, third
