902. Lithocharis brevipennis, n. sp. 

 L. prsecedenti fere similis, fortasse ejus varietas regionibiis valde ele- 

 vatis TenerifFipe propria ; sed paulo minor, angustior, ocuKs sensim 

 minoribus elytrisque brevioribus (sc. prothorace hand longioribus) ; 

 capite rufo-ferrugineo, ad basin vix minus recte truncate. — Long.

Although in colour and outline almost similar to the L. melanoce- 

 phala, I am uncertain whether the present LitJwcharis can be regarded 

 as any modification of that insect peculiar to the loftiest altitudes of 

 Teneriffe. The only examples of it (four in number) which I have 

 myself taken were captured on the elevated Cumbre overlooking the 

 CaFiadas, at nearly 10,000 feet above the sea ; and two more have been 

 communicated by Dr. Crotch, which I have little doubt were met with 

 in the same region. It differs from the melanocejihala in being a little 

 smaller, with its eyes still more minute, and its elytra very appre- 

 ciably shorter (being, in fact, no longer than the prothorax). Its 

 head appears to be rufo -ferruginous (as in the jpaler specimens of the 

 melanocephalcC) , and, if anything, somewhat less straight!}' truncated 

 at the base. 



903. Lithocharis debilicornis. 

 L. subopaca, pallida, subgrosse pubescens ; capite (lato, subobcordato, 

 oculis prominentibus) prothoraceque (breviusculo) rufo-testaceis, 

 alutaceis, sat grosse sed baud profunde punctatis ; elytris testaceis ; 

 abdomine fusco-testaceo ; antennis (brevissimis, articulis inter- 

 mediis brevibus) pedibusque testaceis.— Long. corp. lin. 1^-1-^. 



Lithocharis debilicornis, Woll, Cat. Mad. Col. 194 (1857). 

 Hahitat Teneriffam et Palmam, rarissima. 



I have not taken the trouble to dissect this curious insect ; but I 

 think it far from unlikely that a cai'eful examination of its oral organs 

 would disclose suificient structural peculiarities to render its isolation 

 from Lithocharis desirable, — its greatly abbreviated antennae (all the 

 joints of which, except the basal and apical ones, are much shortened), 

 combined with its prominent eyes and the more fusiform apex of its 

 maxiUary palpi, giving it a character essentially its own. In mere 

 specific details it may easily be recognized by its entirely pallid hue 

 and subopake surface, and by its head and prothorax (the former of
