The spots are numerous in the subsutural depression and 

 form three rows (of which only the median one is at all dis- 

 tinct) elsewhere on each elytron. The metasternum is glab- 

 rous in the middle, but not towards the sides. On both speci- 

 mens before me the pubescence on each side of the basal seg- 

 ment of abdomen is suddenly interrupted, so that at its apex 

 it is glabrous, the three following segments have each a 

 similar but much smaller glabrous space, and these three have 

 as well a small spot of pubescence which is sometimes joined 

 to the lateral stripe. On one of the specimens the pubescence 

 is of an almost snowy whiteness. There are no distinct 

 granules on either prothorax or elytra, although about the 

 base of the latter the punctures are so irregular as to cause 

 (from some directions) the apparent presence of a few. The 

 elytra are not suddenly elevated behind the scutellum. 



In general appearance close to semijjun^ctatiis, but wider, 

 femora edentate, and tibise and tarsi dark. Also very close 

 to the preceding species, but basal joint of antennae consider- 

 ably longer, the two carin?e on each elytron much stronger, 

 with traces of a third and the clothing of abdomen different. 

 It is also rather more robust, with the prothorax much less 

 elevated on each side of the median channel. Perj)leofus is 

 described as having "three well-defined carinae on each of its 

 elytra" ; in the present species two carinas are distinct, but 

 the outer one, if indeed it should be regarded as a carina at 

 all, is very indistinct; the inner one commences quite close 

 to the base, very much nearer, in fact, than ''at a distance 

 from the base about equal to a quarter ot the length of the 

 elytra"; the prothorax also is not ''ruguloso-granuloso." 



Belus pulverulentus, n. sp. 



Black, antennae and claws feebly diluted with red. 

 Clothed with white pubescence, margining eyes, forming an 

 interrupted median line on prothorax, and feeble lateral lines ; 

 forming numerous feeble spots about suture (these more or 

 less tinged with ochreous), and two very feeble rows on each 

 elytron elsewhere; and rather dense, but irregularly distri- 

 buted, on under surface. 



Head with dense and rather coarse punctures; scarcely 

 transversely impressed behind eyes. Rostrum slightly longer 

 than prothorax ; with dense and fine punctures at apex, 

 becoming slightly sparser and larger to antennae, but thence 

 more rapidly so till on the base itself they are coarse. An- 

 tennae thin, moderately long, first joint distinctly longer than 

 second and third combined, eleventh the length of ninth 

 and tenth combined. Prothorax rather strongly inflated to- 

 wards base, with a wide but interrupted median channel,
