wings transparent but with all the nervures and nervules of a drab 

 colour, as well as with brown macules and patches. Head with a 

 black central fuscous patch between the antennae, and nine such 

 patches on the vertex arranged in longitudinal series of three, which 

 do not seem to coalesce in the three examples I have seen ; pro- 

 notum with three distinct uninterrupted fuscous bands and a very- 

 small fuscous dot on each side, mesonotum with on each side three 

 fuscous black bands ending past the middle, a broad central band 

 and on each side of the hind part two superposed macules ; meta- 

 notum with a somewhat narrow median band and a broader lateral 

 one wider at the base than at apex ; legs very nari'owly ringed at 

 apex of femora and tibiffi ; tibial spurs absent. The fore wings bear, 

 each past the first anterior third two oblique brownish bands, the 

 first of which is reduced to small macules, whereas the second, 

 which is almost median, is more distinct, and also a third, past median 

 band much better defined I)ut usually interrupted in the middle, and 

 bounded by the white stigma, which is somewhat elongated ; the 

 whole of the apical area is numerously maculated ; the hind wings 

 have each two or three macules set slightly before the median part, 

 and a past median broad band occasionally interrupted in the middle 

 in the J , with the lower part prolonged horizontally along half the 

 width of the posterior part and continued to the apex as small 

 macules, while the upper part of that band is divided by a 

 moderately broad sub-lacteous interval from a plain, sub-quadrate 

 large patch reaching short of the apex. The nervules and nervures 

 are briefly hairy and the margins very briefly fimbriate. 



Length of body : J 18^ mm., $ 15 mm. ; fore wings expanded

Mykmeleon obtabilis, n. sp. 



Bright yellow ; antennae fuscous with the two basal and the four 

 apical joints yellow; head with two conspicuously raised promi- 

 nences on the vertex, on the space between the antennae is a 

 triangular black patch, and a small black dot on the declivous 

 hind part of each of the knobs ; pronotum with a black median 

 band contracted in the centre, and a dot on each side ; mesonotum 

 with two short diverging basal macules in the centre, a large one on 

 the scutellum and two or three small and irregular on each side ; 

 metanotum with five black macules ; abdomen infuscate, the dorsal 

 segments flavescent for about half the length, apical segment and
