ICHNEUMONINI. 



HopliNineniiM ? leptoeeruM sp. uov. 



Scutellum rouiirily convex ; the sides stoutly keeled to the middle. Median 

 segment short, the apex straight, slightly oblique, the sides shortly toothed ; the 

 base depressed, the areola wider than long, transverse at the base, tlie apex 

 slightly roundly curved inwardly ; it is dearly separated from the petiolar area. 

 The 2nd abdominal segment aciculated, the others smooth ; the ovipositor 

 largely projecting, as long as the last two segmeiits united. Antennse longer 

 than the body, dilated towards the apex, the middle broadly ringed with white. 

 Labrum projecting. Areolet 5-angled ; disco-cubital nervure broken by a slight 

 stump of a nervure ; angled where it issues ; the cubitus faint beyond the stigma. 

 Tarsi long, the apices of the joints spinose. Ventral keel stout, extending to the 

 base of the ovipositor. Apex of abdomen sharply pointed ; there are 7 segments; 

 the last is fully larger than the 6th. 



The antennae are longer than the body; the occiput is roundly emarginate ; 

 temples short, obliquely roundly narrowed; malar space distinct; abdominal 

 petiole slender, not much dilated at the apes. The hind femora reach to the 

 apex of the 4th abdominal segment. Radial cellule wide, not rea<-hing much 

 more than half way to the apex. 



Yellow; a triangular spot covering the ocelli and prolonged down the front, 

 becoming gradually narrowed, the greater part of the occiput, 3 broad lines on 

 the mesonotum. the space at the sides of the scutellum, the base of the metano- 

 tum broadly, the posterior median area and the base of the meso- and metapleu- 

 rse, bluck. The back of the abdomen brownish, tinged with black, the npices of 

 the 1st and 2nd segments broadly yellow; the others are more narrowly and 

 obscurely yellow at their apices. Legs yellow, the hind femora and apical third 

 of hind tibise brown ; the other femora tinged with fulvous behind. Wings clear 

 hyaline, the stigma testaceous, the nervures darker. Smooth and shining; the 

 mesopleuTEe in the centre and, to a less extent, the centre of the metanotum 

 punctured. Areolet narrowed in front, but with the nervures clearly separated ; 

 the recurrent nervure received shortly beyond the middle. Length 5.5 mm. 



Hah. Mexico. 



As I cannot place tliis genus to my .satisfaction I have given a 

 generic and specific description of it. In Dr. Ash mead's table it 

 fits best with Hoplkmeuus. It looks more like a Cryptid than an 

 Ichneumonid. Probably it will form the type of a new genus.
