37. iSciOBius ARROwi, sp. nov. (Plate XIX. fig. 10.) 



Long. 6|-, lat. 3-| mm. 



Head transverse, black, coriaceous, witli dense brown scaling ; 

 forehead scarcely impressed ; eyes moderatelj^ prominent. Rostrum 

 distinctly longer than broad, sides subparallel, gense scarcely 

 dilated ; upper surface deeply impressed, with three narrow 

 carina3, the outer pair parallel to near apex, thence divergent, 

 very finely aciculate, and with dense brovfn scaling. Antenna' 

 long and slender, piceous, with pale pubescence ; scape strongly 

 curved, slender, subcompressed and abruptly clavate ; first joint 

 of the funicle longer than the third. Prothorax rather broader 

 than long, truncate at base and apex, the latter a little narrower 

 than the former, sides slightly rounded, broadest about middle; 

 upper surface convex, with depressed and rather distant granules, 

 except along the central line which is smooth and coriaceous; 

 colour black, the central portion a,lmost bare, the sides with dense 

 brown scaling which almost conceals the granules. Elytra broadly 

 ovate, acuminate posteiiorly, ti-uncate at base, shoulders oblique, 

 sides strongly rounded, broadest before middle ; upper surface 

 with the anterior portion of the disk quite flat, but rising 

 posteriorly to beyond middle, the posterior declivity being much 

 longer and more steep than usual, with fine strife containing 

 rows of shallow punctures separated by minute granules, the 

 intervals almost plane, veiy finely aciculate, with a few scattered 

 minute granules, mostly hidden by the scaling and more notice- 

 able on the declivity ; colour black with brown scaling on the 

 disk, but paler towards the sides and apex, and with a conspicuous 

 pale common V-shaped mark having its apex on the summit 

 of the declivity, the intervals with distant pale setse, which are 

 longer and suberect on the disk, and shorter and depressed on the 

 declivity. Legs slender, piceous, with uniform fine pale scaling, 

 the anterior tibia; slightly incurved at the apex. 



Type in the British Museum. 



Katal [coll. Pascoe\ 



I have seen only the type of this species, which was erroneously 

 referred to Phlyctinus callosus Boh. by Pascoe. The shape of the 

 elytra is unusual and gives the insect a distinctive facies. The 

 specimen is probably a female.

 both sexes ; upper surface slightly impiessed, tricarina,te, the 

 carinfe straight and pai'allel, the punctuation and pubescence as on
