for dark spots on each side of third and fourth abdominal segments ; in addition 

 A\ath numerous stout setae, wider on under-surface than elsewhere, seriate on 

 ■elytra, and becoming thin on legs. 



Head with dense punctures, each containing a scale; a comparatively small 

 crest in front, posteriorly diverging to margin of each eye for a short distance. 

 Rostrum short, concave, and with a few punctures along middle ; sides flat, 

 highly polished, and with rather sparse, conspicuous punctures. Club of 

 antennae elongate. Prothorax with sides strongly and evenly rounded ; punc- 

 tures dense and rather large, but almost concealed. Elytra conspicuously wider 

 than prothorax, sides parallel to near apex ; with rows of large, partially concealed 

 punctures, each containing a stout seta or scale ; interstices evenly convex and 

 wider than punctures, each with a row of setae, and towards base with small 

 granules. Length, 7-9 mm. 



The rostrum concave along the middle and polished on the sides, elytra with 

 even interstices on which granules are few and inconspicuous, and the maculate 

 abdomen distinguish this from all previously described species. Structurally it 

 is closer to R. faceta than to any other species before me, but that species has 

 distinct rows of granules and a white fascia on elytra, sides of rostrum clothed, 

 and abdomen immaculate. As on most species of the genus, the markings of 

 the upper-surface are variable, the scales are black, white, and ochreous, inter- 

 mingled in small patches, on some specimens the white scales are in the majority, 

 on most of the others the ochreous ones are, but these vary from almost white 

 to dark brown ; the scutellum, however, appears to be always clothed with white 

 scales. The granules on the elytra are all small and are mostly on the basal half, 

 tut they are usually concealed by the clothing; the seriate punctures appear to 

 1)e narrower than the interstices, but after the scales have been abraded they are 

 seen to be slightly wider than them. The male has slightly longer legs than 

 the female, and the basal segment of its abdomen is slightly depressed in the 

 -middle, that of the female being slightly convex there. A single specimen was 

 taken on the island, but Messrs. B. A. Feuerheerdt and F. Seeker took others at 

 Lucindale. 



Belus hrimneus, Guer. Fragments of at least nine specimens of this species 

 were taken from the stomach of a thickhead (Pachyccphala gutturalis). 



Desiantha maculata, Blackb. In the original description of this widely 

 distributed species the under-surface was not even mentioned ; on the male there 

 is a conspicuous depression on the basal segment of abdomen, continued on to 

 the second segment and also on to the metasternum ; its apical segment has a 

 small median fovea, sometimes scarcely traceable. On the female the basal seg- 

 ment is convex in the middle and the apical one has a cavity occupying rather 

 more than the median third ; its metasternum has a large depression but smaller 

 than on the male. Numerous specimens from the island may represent a variety 

 of the species, they differ from some cotypes and other specimens in the average 

 size being larger (up to 65 mm.), the elytra less conspicuously maculate, and 

 the scales occasionally with a golden or golden-green gloss. 



Xeda, sp. A single badly abraded specimen of this genus was obtained ; it 

 belongs to a large species about the size of X. magistra or X. fasciata, but could 

 not be identified with certainty. 



Decilaus auricomus, Lea. 

 Eleagna squamibunda, Pasc. 

 Aphela algarum, Pasc. 



A. helopoides, Pasc. One of the specimens of this apterous beach- 

 frequenting species was taken from the stomach of Hirundo neoxena, a rather 

 curious record for this bird, which usually captures its prey on the wing.
