 decreasing in length, eleventh obpyriform. Prothorax much wider 

 at base than at apex ; oblique impressions deep and narrow ; with 

 rather large irregular punctures and with transverse rugulosities, 

 punctures denser at sides than elsewhere ; margins narrow. /SVif- 

 tellum triangular, longer than wide, base notched. Elytra brief!}' 

 oblong, subhumeral lobes not very small ; densely but not very 

 coarsely punctate, and feebly transversely rugulose, posteriorly 

 punctures becoming smaller and irregularlj' geminate in arrange-

 than usual. Apex of prosternitm very wide, feebly rounded and

Bah. Victoria : Gisborne (type in H. H. D. Griffith's 

 collection). 



A very beautiful and decidedly aberrant species. 



Of the species of the subfamily described as having 

 antennae very wide in the middle, Chariderma p^/r//o//fr, 

 Baly, has the prothorax and elytra maculate and the pro- 

 sternum much as in ScJiizostemus ; Aporocera apicalis, 

 Saund., and hicolor, Saund., have the prothorax pallid and 

 the elytra long with large punctures in regular series. 

 Ap. chalyhea, ^Siwnd. (unknown to me), is described as having 

 the prothorax pitchy-black margined with ochraceous, the 

 legs differently sculptured and the elytral sculpture dif- 

 ferent. The following species has also antennae very wide 

 in the middle, but its sculpture and colour are very different 

 and the intercostal process is strongly ridged along the 

 middle. 



Cryptocephalus costipennis, n. sp.

9 . Moderately shining. Black ; muzzle, coxa? and extreme base 

 of tibia} dull red ; prothorax and elytra testaceous, the former with 

 the sides in front and a median line (not quite continuous to apex), 

 the latter with the basal third of the sides and the suture, black. 



Head opaque and densely and coarsely punctate. Antenna? wide, 

 just passing hind coxa?, second joint less than half the length of 

 third, third— fifth very wide, the third slightly the widest, the fifth 

 slightly the longest, sixth — tenth regularly diminishing in length 

 and width, eleventh slightly longer and narrower than tenth, apex
