•■>!K)7. Rachidiscodes altipennis sp. iiov. 



Nitid. nearly uiahious. liaviii<i only a few yellowish scales on the thorax 

 and between the eyes ; pieeous. elyt la i-ufoseent aloiio; the middle, antennae 

 and legs light castaneous. 



Rostrum smooth in front, bisulcate behind, and with an additional 

 latei'al stria that might be mistaken for the scrobe. Thorax a third longer 

 than broad, widest at the middle ; its sculpture consists of moderate 

 punctures and obtusely elevated intervals. Elytra not double the lengtli 

 of thorax, strongly arched and on a higher plane than it is, rounded, widest, 

 and most convex behind the middle, and becoming very narrow at the 

 extremity ; on each elytron there are 4 rather broad, deep, apparently 

 impunctate dorsal striae, those along the sides are less distinct ; interstices 

 convex, the pair near the suture are convex from base to apex, the 3rd 

 becomes iiidefinite near the base, the 4th behind.

Allaorops gen. nov. 



Minute, convex, glabrous. Rostrum arched, stout, as long as thorax. 

 Scrobes open above, dilated between the middle and apex, obliquely pro- 

 longed underneath. Eyes small, depressed, indistinct, lateral, tlieir distance 

 from the thoracic apex equals their own length. Thorax without oculai- 

 lobes, as long as broad, oviform, base and apex truncate. Scutelluni 

 absent. Elytra only a third longer than thorax, as broad as it is, and 

 slightly emarginate, at the base, subovate, strongly arched and subvertical 

 behind. 



Scape stout, gi'adually incrassate, inserted between the middle and apex 

 and reaching the front of the eye. Funiculus 7-articulate, 2nd joint oblong, 

 as long as the basal, the others successively incrassate, transverse. Club 

 oblong- oval. 



Femora elongate, simple. Tibiae straight, also long, indistinctly 

 mucronate. Tarsi rather short, intermediate joints transverse, penultimate 

 not at all expanded, excavate above near the apex only ; terminal 

 nearly as broad and as long as the preceding two iinited, with minute 

 curved claws. 



Prosternum elongate, emarginate in front, coxae large, prominent, and 

 .contiguous, situated in the middle. Metasternum short. Abdomen 

 elongate, basal segment rounded between the widel}' separated coxae, twice 

 the length of the next in the middle, its hind suture distinct and almost 

 straight, 5th longer than the deeply divided shoit 3rd and 4th together, 

 transversely quadrate, finely marginate, medially emarginate at apex. 



Resembles Allaorus in contour, structurally more nearly allied to 

 Rachidiscus, but easily separable therefrom by the rostrum being 

 subpterygiate before the middle, by the small distant eyes, considerably 

 less medially nari'owed ])ody. different tarsi, kc. 



3908. Allaorops carinatus s]). nov. 



Nitid, oblong, slightly narrowed towards the middle, glabrous ; nigro- 

 piceous, legs pitchy-red, antennae and tarsi fusco-rufous.
