296 Mr. J. Scott on new Genera and Species 



Genus Sehirus, Am. et Serv. 

 Sehirus triguttatus. 



Black, shining, thickly punctured ; margin of the pronotum 

 and elytra, two spots upon the latter, apex of the scutellum, 

 and basal two thirds of the tibise exteriorly white. 



Head black, thickly and deeply punctured ; anterior margin 

 reflexed. A ntennai pitchy black ; first and second joints short, 

 subequal, third about as long as the two former, fourth shorter 

 than the fifth, apex of the latter reddish brown. 



Thorax. — Pronotum black-punctured, except a transverse 

 space next the anterior margin ; the punctures at the anterior 

 margin and on the sides towards the anterior angles finer and 

 more thickly disposed than those on the posterior portion of 

 the disk ; lateral margins white. Scutellum black, sparingly 

 and irregularly punctured, posteriorly somewhat transversely 

 wrinkled ; apex white. Elytra black, somewhat thickly 

 punctured. Corium : anterior margin white ; disk with an 

 unpunctured, short, white oblong streak, placed somewhat 

 obliquely and pointing towards the apex of the scutellum. 

 Membrane brown. Legs black : tibiw black, basal two thirds, 

 except the knees, exteriorly white ; spines black : tarsi some- 

 what reddish, third joint piceous. 



Abdomen above piceous, beneath black. Connexivum : ex- 

 terior margin narrowly white. 



Length 2£ lines. 



This insect somewhat resembles a small S. biguttatus, with 

 the addition of a white apex to the scutellum ; but here ends 

 all likeness, as the sculpture is different, and the exterior 

 margin of the tibias from the base downwards, for a consider- 

 able distance, is white. There is also a great difference in 

 the length and proportion of the joints of the antennas in the 

 present species when compared with others of the genus ; but 

 I am averse to creating a new genus for the reception of this 

 species on this character alone, as I have only seen a single 

 example. 



Family Sciocoridae. 



Genus DEINOSTIA, Stal. 

 Drinostia Lewisi. 



Pale luteous, finely black-punctured. Elytra : anterior 

 margin broadly white. Sternum and abdomen with a more or 

 less distinct black -punctured streak down the sides ; the latter 

 in addition with a broad black line down the centre. 



Head thickly black-punctured, except a small space next 

 the eyes, in which is a single slightly curved row of punctures.
