of antennae testaceous, rest piceous or blackish, third and fourth 

 equal. Thorax twice as broad as long, sides acutely angulate 

 near base ; anterior sulcus nearly entire, very narrow ; surface 

 sculptured and pubescent like the head. Scutellum trigonal, 

 smooth. Elytra with deep basal depression, strongly punctate- 

 striate, punctures very closely placed, interstices strongly costate 

 at the sides and to a less degree on the disc. Legs testaceous ; 

 femora more or less piceous at apex, with a small tooth beneath. 

 Prosternum twice as broad as long, punctured. 



Length 3 mm. 



Hob. Southern India: Nilgiris (Coll. H. E. Andrewes). 



606. Nodostoma maculiceps, sp. n. 



Piceous or black beneath ; terminal joints of antenna? black, 

 basal joints flavous ; head and thorax fulvous, each with a black 

 spot : elytra testaceous, sutural and lateral margins anteriorly, 

 a spot below base and two behind the middle, black ; femora more 

 or less spotted. 



Head dark fulvous, closely and strongly rugose and punctured ; 

 clypeus rugose like the rest of the head, its anterior border slightly 

 emarginate ; antennto black, slender, basal four joints flavous, 

 third slightly shorter than the fourth, terminal joint elongate, 

 thickened. Thorax scarcely twice as broad as long, convex, sides 

 obsoletely angulate near base, gradually narrowed at apex ; surface 

 very strongly rugose and punctured, sparingly clothed with short 



Sibescence; anterior sulcus faintly marked. Scutelluin nearly 

 ack. Elytra oblong, transversely depressed below base, each 

 with ten strongly raised longitudinal costs?, the interstices strongly 

 punctured, the suture and an elongate spot or short stripe behind 

 the middle on the fourth costa obscure piceous. Anterior femora 

 strongly thickened, with a large black spot below near apex. 



Var. Elytral and femoral markings obsolete. 



Length 2|-3 mm. 



Hob. Southern India: Madura; Anaimalais (Coll. H. E. An- 

 drewes) Trichinopoly ; Pondicherry (Colls. Brussels Mm. Jacoby). 



A very variable species in regard to size and markings, but well 

 distinguished by the closely rugose head and thorax, central spot 

 of latter, and the elytral cost*. In well marked specimens the 

 elytral spots are black, in others only fuscous or absent altogether. 



607. Nodostoma instabile, sp. n. 



d . Testaceous. Head strongly and closely punctured ; clypeus 

 not separated from the face : antennae entirely testaceous, second 

 joint proportionately long, but slightly shorter than the first and 

 third joints, terminal joints rather thickened, extending bevond 

 middle of elytra. Thorax transverse, strongly narrowed in front, 

 sides with a blunt angle near base, anterior sulcus entire; surface 

 closely rugosely punctured, interstices sparingly pubescent. Elytra 

 rather long, with distinct depression below base ; puncturatiou
