central, dentiform, erect plica (the depressed area appearing 

 trisulcate), the juxta-ocular prominences large, dentiform, 

 ciliate anteriorly, the face shorter than in //. amcenus ; pro- 

 thorax also shorter and more transverse, broadly explanate 

 at the sides behind the middle and then abruptly narrowed 

 to the base, the l)lack discoidal patch subqnadrate, excised 

 in front, the rest of the surface testaceous ; elytra blue or 

 bluish-green, with the apex narrowly testaceous in some 

 specimens, densely, rugulosely punctate ; legs and abdomen 

 testaceous, the metasternum metallic, the pygidium nigro- 

 biraaculate ; anterior tarsal joints 1 and 2 slightly thickened, 

 2 black at the tip. 



$ . Antennae short, slender, joints 6-9 obsoletely nigro- 



maculate ; head with the basal half black ; pygidium black. 



Fa)\ The elytra with two broad bluish-green fasciae — one 



basal and the other subapical, the latter narrowly interrupted 



at the suture, — for the rest testaceous. (^ .)

Described from 5 cJ c? , one ? , and a (^ of the maculate 

 variety, the males of the two forms agreeing precisely in 

 their structural characters. Gorham, in his second account 

 of //. amcenus \ noticed the colour of the antennae of one of 

 these males ; but he failed to observe the difference in struc- 

 ture of the antennae themselves, as well as that of the head 

 in the same sex. H. lineaticornis and H. braunsi also have 

 some of the antennal joints similarly lineate above in ^ . 

 The variation in the colour of the elytra is quite exceptional 

 in the present genus. 



23. Hedybius braunsi, sp. n. 



$ . Moderately elongate, shining, clothed with whitislj 

 pubescence intermixed with long erect hairs; the head and 

 prothorax sparsely, minutely, the elytra densely, finely, 

 rugulosely punctured. Antennae slender, tapering, nearly 

 as long as the body, testaceous, joints 1-i or 5 nigrc- 

 lineate above, 3 and 4 without shining black area beneath^ 

 3-5 elongate-subtriangular, equal in length, 6-11 still 

 longer, 11 longer than 10 ; head (PL XIV. fig. 22) broad, 

 tlavous or testaceous, black at the base (except at the micld+e 

 of tiie vertex), depressed and trifoveate between the eyes 

 (tlie two anterior foveae oblique and usually black), the 

 depression limited on each side by a concave, oval, raised
