and a narrow line on the inner side of the scutellum process whitish testaceous ; 

 the basal half of the femora tinged with fuscous on the outers^de. Wings 

 hyaline, the nervures fuscous. Female. Length, 4 mm. 



Head opaque, coarsely shagreened, the sides of the vertex almost reticu- 

 lated ; frontal depression moderately wide and deep, the sides keeled, the 

 top rounded, enclosing the front ocellus. Temples short, the occiput oblique. 

 Malar space distinctly longer than the eyes. The head is short and is clearly 

 narrower than the thorax. Prothorax smooth, the upper apical part of the 

 propleurae with a few obscure striae ; the base with a sharp slope, margined 

 round the edges, narrowed to a point above. Mesonotum striated, the striae 

 cltarly separated, the top depressed in the centre, smooth, obliquely nar- 

 rowed from the top to the middle, where it is deepest. Scutellar process 

 extending to the apex, of the 3rd abdominal segment, of equal width to the 

 apex, which is oblique ; they are closely, strongly regularly longitudinally 

 striated, are slightly depressed in the middle above. Metanotum smooth, 

 the sides keeled, a stouter keel down the middle, it has a straight, oblique 

 slope. Abdominal petiole twice the length of the hind coxae. 



The form ot the scutellar process is different from what it is in the type 

 of the genus — platycerus ^shm.,Mem. Cairn. Mus. i, PI. XXXV., f. 3, — it 

 being in that species much wider, bulging out in the middle and rounded at 

 the apex, not oi equal width and obliquely truncated at the apex. There 

 seems to be also a radical difference in the relative lengths of the antenna 1 

 joints, but I am not sure that I understand the description given 



Torymix.e. 



Torymus guyanaus, sp. n. 



Antennal scape fulvous, the flagellum black, the basal joints fuscous. 

 Head green, tinged with blue on the top and outer orbits, covered with short, 

 white pubescence. Mandibles dark fulvous, the teeth black. Face covered 

 with i ound, distinctly separated large punctures ; sides of front finely closely, 

 irregularly striated. Vertex aciculated ; a distinct, clearly defined furrow 

 runs down, slightly obliquely on either side of the middle, to the antennae. 

 Prothorax finely distinctly aciculated, broadly purple in the middle, the base 

 and apex green. Mesonotum green, the base and apex largely purple ; the 

 parapsidal furrows distinct ; the central division coaisely aciculated, the 

 lateral lobes finely reticulated, more strongly on the apex than base. 

 Scutellum closely aciculated, the basal three-fourths with scattered 

 punctures — Pro-and mesopleurae aciculated, almost punctured, the 

 former largely purple above. Metapleurae smooth. The pubescence 

 on the thorax is sparse and white. Abdomen mostly blue largely varie- 

 gated with violaceous and purple tints. Four front coxae violaceous, 

 the middle blue at the apex, the hinder dark green ; all are closely distinctly 

 punctured ; the four front femora brown, testaceous at the base and apex, as 

 are also the trochanters, the hinder femora green, the base, apex and lower 

 side purple ; the apex of the femora and the tibiae testaceous, the hinder
