carinate. Scutettum broadly in the centre and the postscutelluin 

 (except centrally) fulvescent, the former finely and transversely 

 punctate. Abdomen nitidulous and dark red, with the petiole 

 paler ; second segment with two broad and obscure fulvous discal 

 lines ; remainder with concolorous lateral lines, basally broad 

 and apically obliquely constricted; venter flavescent, with the 

 basal segment flavous ; terebra 60 rnilliin. in length with the 

 valvulae dull fulvous towards their apices. Leys red, with the 

 anterior coxae and trochanters flavous ; hind coxa; dark red and 

 basally marked with black and flavous, their tarsi subflavescent. 

 Winys deeply fulvescent-hyaline, with their apices hardy infumate ; 

 costa and stigma fulvous, nervures black ; areolet triangular, 

 emitting the recurrent nervure from its apical fourth ; internal 

 nervure of areolet oblique and straight, the external curved. 



Length 38-39 millim. 



ASSAM: Khasi Hills (Rotlmey). 



Type in the Oxford Museum. 



This species is quite distinct from the cosmopolitan R. persua- 

 sm-ia, L., which has no fulvescent markings on the body, but is 

 banded or laterally spotted with stramineous.

 GENOTYPE, L. maculipennis, Cam. 



Head not strongly buccate posteriorly ; clypeus basally separated 

 from the face and laterally depressed at the base ; mandibles short, 

 stout and apically bidentate. Meta- shorter than meso-thorax ; 

 mesonotum trans-strigose, with the notauli anteriorly deeply 

 impressed ; metanotum gradually declivous throughout and tri- 

 angularly impressed basally ; spiracles large, elongate and rounded 

 at both extremities. Scutellum deplanate and pale. Abdomen 

 glabrous and not impressed ; basal segment shorter than the 

 second, with the spiracles oval, oblique and approximate to the 

 base ; intermediate segments not longer than broad, aciculate and 

 apically neither emarginate nor incised ; of tf strongly convex 

 discally ; terebra longer than body. Legs stout ; hind cox* 

 parallel-sided and not inflated; tarsi spinose, with the claws 

 simple, hind ones as long as their tibiae, with the last joint about 

 thrice the length of the penultimate. Areolet rounded above, as 

 long as or but slightly longer than its petiole, and emitting the 

 recurrent nervure a little before its centre ; upper basal nervure 

 emitted from the median nervure distinctly before the lower ; 

 radial cell somewhat narrow, and lanceolate at both extremities ; 

 lower wing with the first recurrent postfurcal, emitting the 

 nervellus from its junction with the median nervure. The sexes 

 differ only in the form of the abdomen.
