Oblong-ovate, slightly depressed, subparallel, impubescent, pale 

 yellow, shining. Head short, small, transverse, not produced in 

 front ; eyes large, globular, and prominent (not extending laterally 

 so far as the humeral angle of the thorax) ; between the eyes, and 

 above the insertion of the antennae, is an obscure longitudinal de- 

 pression ; surface impunctate, testaceous, somewhat clouded with fus- 

 cous, glabrous. Thorax transverse, rectangular, in front distinctly 

 emarginate ; the anterior angles depressed, but subacute ; the sides 

 marginate; at the base is a narrow transverse thread-like fovea, 

 which is deflected abruptly into the margin of the base before it 

 reaches the humeral angles ; surface impunctate, of the same colour 

 as the head, shining. Scutellum triangular, impunctate, flavous. 

 Elytra parallel, subcylindrical, the sides distinctly marginate ; punc- 

 tate-striate ; the surface near the scutellary angles slightly gibbous, 

 croceous (in different examples the shade of yellow varies ; in some 

 it has the depth of colour of the yellow band of Trichius fasciatus, 

 while in others it is almost pale flavous). Antennae filiform, of the 

 length of the elytra; the first joint large, inflected outwards and 

 dilated at the base ; the rest as in the adjoining species ; the first to 

 the fourth rufo-ferruginous, the rest fuscous. Legs flavous or cro- 

 ceous, with the tarsi and (more or less) the anterior tibiae black. 



Var. A. Head and thorax rufous ; elytra flavous, irrorated (espe- 

 cially towards the apex) with black ; antennce rufous, with the fifth 

 to the eleventh joints fuscous ; legs rufous, the tarsi and anterior 

 tibiae being black. 



The above description of the insect was taken from a male ; that 

 of the variety from a female. The different sexes of this species have 

 the same characteristics that obtain among its congeners. The males 

 are smaller, less robust, more depressed ; the head is smaller, while the 

 eyes are larger and more prominent ; the legs have slightly, in reality 

 (as well as when contrasted with the different size of the bodies), a 

 longer development ; and the antennce are very apparently more 

 produced. 



This species is evidently subject to great variation in the shades 

 of its colouring ; in the examples before me, no two specimens abso- 

 lutely agree in every point. It is at once separated from jucundus,
