 Exp., II, p. 284 (1912), ?. 



This differs from velox, Sm., in the narrower pygidial 

 area. 



Gastrosericus ncavci, sp. n. 



9 . Nigra, albopilosa ; orbitis iuterioribus verticem versus liaud 

 convergentibus, genis pone oculos spina magna obtusa instructis ; 

 alis fusco-hyalinis ; tibiis posticis intus pallide flavis. 



Long. 7 mm. 



5 . Head broad, tbe eyes not converging towards the vertex, their 

 inner margins parallel, separated on the vertex by a distance equal 

 to about two-thirds of the length of the flagellum ; the third joint 

 of the flagellum fully as long as the second. Clypeus very broadly 

 rounded at the apex, covered with short white pubescence ; head 

 very closely and distinctly punctured, a short longitudinal sulcus 

 above the base of the antennae ; posterior ocelli oblique, situated on 

 a rounded prominence which is not divided by a sulcus, a narrow 

 curved groove behind the posterior ocelli. Cheeks more than half 

 as broad as the eyes, armed with a short, strong, blunt spine. 

 Pronotum depressed below the mesonotum ; the latter closely and 

 rather strongly punctured, slightly depressed in the middle on the 

 anterior margin. Mesopleurae and scutellum closely punctured ; 

 median segment shorter than the mesonotum, transversely rugulose 

 and rounded posteriorly. Abdomen very minutely punctured ; the 

 first segment subpetiolate, the second slightly constricted at the base. 

 Anterior coxae armed with a long seta. Second abscissa of the 

 radius scarcely half as long as the first ; the two recurrent nervures 

 unite before their junction with the cubitus at one-third from the 

 base of the second cubital cell, so that the second discoidal cell is 

 distinctly petiolate. 



Hob. British East Africa, Upper Kuja Valley, S. 

 Kavirondo ; 4,200 ft. {S. A. Neave), May 5-8. 



Type in B. M. 



This species is easily distinguished by the great distance 

 between the eyes on the vertex and by the spine on the 

 cheeks. 



Feb. 11, 1913.
