372 Mr. T. V. Wollaston on the Tarphii. 



more elongate and fusiform. And they recede from the Tavphii still 

 further in having no nodules and interrupted ridges on their elytra, 

 and in their pronotum being impressed along the centre of its base 

 with a deep transverse line. 



On the other hand, in their general facies and setose surface, no 

 less than in the construction of their antenna; and 4-jointed feet, 

 and in the shape of their upper Up, and of their quadrate, corneous 

 ligula and mentum, these insects are alike coincident with TarjyJiius, 

 which is, I believe, their nearest known aUy. 



After these few remarks, therefore, I think that the following 

 short comparative diagnosis will be sufficient to indicate the group 

 (for which I would propose the name of Tarphiodes), both abso- 

 lutely and with reference to the exact points in which it diifers from 

 Tarphius. 



Genus Taephiodes (nov. gen.). 



Corpus ut in Tarphio, sed majus, interdum alatmn; oculis majoribus, 

 magis prominentibiis necnon interdum (una cum pedibus) setosis ; pro- 

 thorace ad basin in medio liuea transversa profunda impresso, subtus 

 simplici (nee pro autennarum receptione utrinque excavato) ; scutello 

 scutiformi, plus minus distincto ; metasterno longiore, postice in medio 

 (inter coxas posticas) plus minus inciso vel emarginato (nee recte 

 trimcato) ; elytrk simplicibus (nee nodosis nee costatis). Antcmice 

 (PI. XVIII. 1 a) et instrumenta cibaria fere ut in Tarphio ; sed mandibtilis 

 (1 c) pavdo minus acutis, subtriangularibus ; palpis longioribus, max- 

 illaritim (1 d) articulo secimdo paulo magis inflate, ultimo longiuscido 

 apice oblique truncate ; lahialium (1 e) articulo ultimo multo longiore 

 ac magis fusifonni. Pedes ut in Tarphio, sed setosi et postici ad basm 

 minus distantes. 



A Tarphius, et dbos, forma. 



[Typus Tarphiodes Boioringii.^ 



§ I. Corpus sat magnum, ; oculis magnis, setosis ; scutello distincto, 

 scutiformi ; alis sat magnis. 



Tarphiodes Boivnngii, n. sp. 



T. paraUelo-oblongus, niger, vix subnitidus, setis robustis erectis fulves- 

 centibus parce tectus ; protborace brevi, in disco tuberculis maximis 

 valde depressis sed versus latera tubercidis minoribus elevatioribus 

 distantioribus obsito, ad latera paulo sed ajqualiter rotundato ; el}tris 

 seriatim tuberculatis ; antennis piceo-ferrugiueis ; pedibus piceis, valde 

 setosis.
