CHALCIDOIDEA BRED FROM GLOSSINA MORSITANS.

nov. 



Stomatoceras (Centrochalcis) exaratum, sp. 



Distinguished chiefly by the colour and the sculpture of the propodeon. 



?. A very dull black species, nowhere paler from the dorsal aspect and with the 

 ventral surface nearly as dark, only the edges of the sclerites obscurely brownish, 

 ovipositor hardly appreciably lighter below. Abdomen shining only on a portion of 

 the 1st and 2nd segments. Antennae : scape brown, or medianly extensively 

 blackish brown, lighter at base and apex ; 1st funicular wholly clear reddish brown, 

 2nd like the first but narrowly darker dorsally and apically ; remainder of the 

 antennae nearly black ; the extreme tip of the club obscurely paler in transmitted 

 light. Wings : veins blackish brown ; below the marginal and the uprise of the 

 submarginal is a blackish brown band or cloud stretching to the posterior margin, 

 before which it slopes towards the apical edge. Outside the dark area is a clear band 

 descending straight at first below the end of the radius, then curving forward at about 

 half-way to the posterior angle of the wing, before which it ends indefinitely ; between 

 this clear band and the broadly pale apex of the wing is a second blackish brown cloud.

lighter posteriorly. Hind wing hyaline. Legs : all coxae black ; fore and mid legs 

 castaneous or reddish brown, only the claws and empodia black. Hind legs with the 

 trochanters dark chestnut, this tint continuing mainly on the base of the femur outside, 

 and along the ventral edge half-way to the median prominence, also on apex ; femur 

 otherwise black externally ; internally the basal two-thirds black, merging gradually 

 to castaneous at the apex. Tibia blackish brown, darkest along the lower edge, where 

 it folds against the femur ; tarsi dark castaneous. Pubescence generally silvery, 

 ref ringent, but light tawny on the apex of the tibia and on tarsus of hind legs. 



Head triangular from in front ; breadth : depth, as 15 : 13 ; base line of the eye 

 cutting the mid fine at two-thirds. Orbits not very divergent ; eyes at the base 

 separated by two diameters, on the vertex by one and a half ; eyes shortly and 

 slightly pubescent. In width the head just exceeds the prothorax and about equals 

 the abdomen, but is distinctly less than the distance between the extended tegulae 

 (cf. S. micans). The punctures of the head bear, as on the thorax, minute stout 

 silvery bristles, which form a definite row only along the orbits. Antemiae twice the 

 distance between the vertex and cl)rpeal edge ; length, 2 "8 mm. Scape fourteen 

 times as long as broad, and only a little shorter than the five succeeding joints ;
