PHYTOPHAGOUS AND PARASITIC HYMENOI'TRIIA. IIU 



the lower third of the mesopleurse , the mark rounded at the base and 

 apex, a large obHque mark on the apical half of the metapleurse, 

 united to the lateral mark on the metanotum , the apices of the basal 

 two abdominal segments broadly, a large mark on the sides of the 

 third segment, its apical half dilated inwardly, a line, narrowed at 

 the apex on the sides of the fourth and the apical segments, pale 

 yellow. Legs rufo-fulvous, the four front coxa* and trochanters 

 yellow, the hind coxae black, tinged with brown at the apex, yellow 

 for the greater part above, trochanters black below, yellow above, 

 their tibiae and tarsi infuscated at the apex. Wings hyaline, the 

 nervures and stigma black. Antennae longer than the body, the 

 middle broadly clear white. ?. 



Length 5-6 mm. 



Ex pupse of Michroeseus ohlatarkis. 



Haputale, January. 



Face punctured, but not closely or strongly ; the clypeus smooth, 

 with some scattered punctures above. Front and vertex smooth. 

 Mesonotum, lower half of mesopleurse and mesosternum closety 

 punctured. Base and centre of metanotum smooth, the edges of 

 the areola and the posterior median areae with a narrow striated 

 border, the other areae aciculated. Metapleurae more strongly 

 punctured than the mesopleurse. Post-petiole closely rugose and 

 finely striated ; the second and third segments closely punctured. 

 Gastrocoeli moderately' deep , smooth, yellowish testaceous. 



Earrana, gen. no v. 



Median segment smooth, with one transverse keel behind the 

 middle ; long, gradually rounded towards the apex ; the spiracles 

 large, about three times longer than wide. Abdominal petiole long, 

 slender, not much dilated at the apex, the spiracles placed imme- 

 diately behind the middle ; the segments smooth ; the ovipositor pro- 

 jecting. Areolet punctiform as in Mesostenus, open in front ; 

 transverse median nervure received behind the transverse basal ; 

 the transverse median nervure in hind wings broken in the middle. 

 Parapsidal furrows deep. Thorax more than three times longer than 

 wide. Legs long and slender ; the hind coxae three times longer than 

 wide ; the fore tarsi twice the length of tibiae ; claws moderately 

 long, slender. Head slightly wider than the thorax. Metapleuial 

 keels stout, reaching to the hind coxae. Eyes large, reaching to 

 the base of the clypeus, there being a clear malar space. Mandi- 

 bles edentate, gradually narrowed towards the apex. 



The type of this genus is a peculiar insect. It has the deep parap- 

 sidal furrows and the furrow on the lower part of the mesopleuise of
