species of Galerucidce. 103 



for the insect : the Cape Town specimen agrees entirely with the 

 type in the Banks' collection, which must find its place in a new 

 genus allied to Rupilia and allied genera. 



The original specific name of ruficollls, altered by von Harold 

 to erytltrodera, can therefore be restored, although the thorax in 

 the type, and in my specimen, is more flavous than rufous. The 

 following is the diagnosis of the genus, and the description of 

 the species : — 



PsEUDORUPiLiA, n. gen. 



Body ovate, dilated posteriorlj' ; head very broad, not narrowed in 

 front ; eyes rather small ; palpi slender, the apical two joints elongate ; 

 antennae subfiliform ; thorax transverse, the sides rounded, the middle of 

 the anterior and posterior naargin constricted ; scutellum large ; elytra 

 shorter than the body, their epipleurce very broad anteriorly, entirely dis- 

 appearing below the middle ; legs robust ; tibiae with their outer edge raised 

 in shape of a ridge, unarmed, the first joint of the posterior tarsi as long as 

 the following two joints together ; claws appendiculate ; prosternum 

 invisible between the coxas ; metasternum short, the anterior coxal cavities 

 open. 



This genus bears a great resemblance to the Australian 

 genus Rupilia, but is distinguished by the more slender antennae, 

 the want of the elytral epipleuree below the middle, which in 

 Rupilia extend to the apex, and by the appendiculate claws. 



Ps EUDORUPiLiA RUFicoLLis, Fabr. 



Flavous ; the head, antennae, scutellum, the legs, sides of the breast, and 

 the base of the abdominal segments, black ; thorax and elytra finely punc- 

 tured. Length, '2f lines. 



Head broad and robust, black, impunctate, transversely grooved between 

 the eyes, the frontal elevations trigonate, nearly contiguous ; clypeus trans- 

 versely raised ; labrum flavous ; mandibles robust and elongate ; antennae 

 black, the first joint short and thick, the second very short, the third and 

 fourth joints as long as the first, the following four joints, shorter, the rest 

 broken off; thorax twice as broad as long, constricted at the middle, the sides 

 strongly rounded, the anterior angles distinct, the posterior ones obsolete, 

 the surface very minutely punctured, flavous, the middle of the disc stained 

 with fulvous ; scutellum broader than long, black ; elytra widened posteriorly, 

 their apex broadly rounded, the surface finely punctured and wrinkled ; 

 under side flavous ; the sides of the breast, the legs, and a transverse band 

 at the base of each abdominal segment, black. 



Hab. South Africa, Cape Town (St. Helena ?).
