hairs ; the tarsi increase in length from the front, and are yellowish. 

 Palpi testaceous, the penultimate joint infuscate. 



This insect, in form, recedes from Gyrophc&na and approaches 

 Dasynotus, but is distinct from both. Its conspicuously red elytra will 

 lead to its recognition. 



Length, 2-2 J lines ; breadth, \. 



I found two examples at Parua. 



Dasynotus. 



Nov. gen. 



Labrum transversal, truncate in front, with a large membraneous 

 space separating it from the forehead. Labial palpi short, tri-articulate, 

 sub-equal, gradually narrowed ; the second and third joints of the 

 maxillary equal, thickened towards the extremity, fourth aciculate. 

 Mandibles prominent, unarmed, straight externally, acute and curved at 

 apex. Antenna short or moderate, their three basal joints elongate and 

 of nearly equal length ; joints four to ten gradually but strongly incras- 

 sated, eleventh sub-conical, larger than the preceding two. Eyes small, 

 oblique, not prominent. Head moderate, a little produced anteriorly, 

 the space behind the antennae quadrate, with rounded angles, and 

 united to the thorax by a short, broad neck. Prothorax rather small, 

 not much longer than broad, sub-truncate at the base, narrowed in front 

 and behind, but so as to be cordate rather than oviform; it is mar- 

 gined. Scutellum distinct, triangular. Elytra about as broad as long, 

 always broader than the thorax, the external angles projecting behind, 

 widely emarginate at the suture, with an obvious sinuation near each 

 side -j they are slightly narrowed towards the base and apex. Abdomen 

 elongate, margined laterally. Legs moderately long ; femora slightly 

 notched near the extremity ; tibia simple ; tarsi pentamerous, their ter- 

 minal joint longest. 



Body elongate, not depressed, hirsute, usually brightly coloured. 



171. D. flavescens, n.s. Antennce reddish, pubescent; head 

 and thorax reddish also, legs palpi and elytra fulvous, abdomen varie- 

 gate, chiefly yellow. Head sub-quadrangular behind the antennae, the 

 inter-antennal and a triangular space between the eyes smooth and 

 shining, the rest rather coarsely and closely punctured, with a few scat- 

 tered yellow hairs ; mandibles red and glossy. Antennce short and 

 robust ; their two basal joints about equal, the first thickened towards 

 its apex, second cylindrical and slightly longer than the third ; joints 

 four to ten decrease in length but become transverse, the tenth being 

 strongly transversal ; eleventh large, almost conical, nearly as long as 

 the preceding three conjointly. Prothorax finely margined, .rather 

 longer than broad, its sides from the base to beyond the middle nearly 

 straight, narrowed anteriorly, posterior angles not acute j there ' is a 

 depression before the scutellum, and a broader but shallow one on each 

 side of the middle, and its whole surface is coarsely and closely punc- 

 tured. Scutellum punctate. Elytra scarcely longer but considerably
