latter having a relatively smaller subtriangular head, straighter sides to 

 the prothorax, and the elytra broadly arcuato-explanate before the 

 middle, without tubercles, costae, or apical sulci, theii' dorsal surface 

 being regularly convex.

Hah. India, Sarda in Bengal {F. W. C). 



Two specimens from the Ganges region, Bengal, are provisionally 

 referred to this species, the types of which were from Amu Daria (Oxus) 

 and Syr Daria (Jaxartes), Turkestan. They are slightly larger (length 

 a little over 1 mm.) than the measurement given by Sahlberg (0'9 mm.), 

 and have the head red in front (instead of black) ; but as the types are 

 said to vary in colour, and some allowance must be made for the degree 

 of maturity of these insects, too much reliance need not be placed on 

 these characters. The genus, in any case, has not been recorded from 

 India, the only other known representative being the Mediterranean 

 M. murinits Kies., wdiich is a larger and broader insect. 



Ilydnohius contractus, n. sp. 



Oval, very convex, shining ; testaceous, the eyes black, the aatenual club 

 slightly infuscate. Head broad, finely punctured, the eyes rather small ; 

 antennae slender, with the 5-joiiited club stout, joint 8 small. Prothorax 

 trfiusverse, rounded at the sides, wider towards the base, the hind angles 

 almost obliterated, the base margined; closely, conspicuously, uniformly punc- 

 tate. Elytra comparatively short, with regular rows of moderately coarse 

 punctures placed in almost obsolete striae, the striae becoming slightly sinuate 

 on the disc and the puncturing more confused towards the sides, the interstices 

 each with a row of punctures which are scarcely finer than those of the striae, 

 the humeri obtuse. Length 1| mm. 



Rah. India, Sarda in Bengal {F. W. C). 



One specimen, obviously 5 , the posterior femora being unarmed. 

 Shorter, smaller, and more convex than the European H. punctatus and 

 H. pz/nctatissimiis, the antennae slender, with a stout club. The only 

 described Indian Hydnob/us is H. tro])icus Motsch. (Bull. Mosc. xxxix, 

 p. 397, 1866), from the mountains of Nuweiu Elia, Ceylon, which is 

 characterized thus : — " Statura et color H. piinctati sed paulo minor. 

 Ellipticus, subconvexus, vix punctatus, nitidus, fulvo-testaceus, oculis 

 nigris ; elytris punctato-striatis, interstitiis planis, subtilissime rugulosis. 

 — Long. 1 1., lat. \ 1." This species, omitted from the " Munich Cata- 

 logue," must be different from the one here described.
