120 SPOLIA ZEYLANICA. 



interrupted above. Petiole above black with two rather indistinct 

 yellow streaks on the sides and a yellowish band just before apex. 

 Basal segment with two oval spots laterally and a broad sharply 

 defined band along the basal portion yellow ; above this band the 

 segment is black, merging into 'reddish brown towards petiole; 

 following segments reddish brown touched with yellow on the 

 apical margins. Wings flavo-hyaline along the costal margins, the 

 rest fusco-hyaline with a dark fuscous spot covering half the radial 

 cell and extending down into the cubital cell. 



This species may be easily mistaken for Ichnogaster fraterna 

 (Bing.), which it resembles in form and especially colouration, but 

 an examination will at once reveal the genus, and the intermediate 

 legs will be found to bear only one tibial calcar, besides the claws of 

 tarsi being dentate, which at once separates it from Ichnogaster. 

 Length to anterior margin of basal segment 13 to 14 mm. Expanse 

 20 to 22 mm.

Head, thorax, and abdomen smooth, shining, and punctured ; 

 the punctures close and even on the front, thorax, basal, and 

 anterior margins of segments 2 and 3 ; vertex and petiole shining, 

 with few scattered shallow punctures. Median segment rounded 

 and steeply sloped with a deep longitudinal groove ; petiole with 

 two lateral blunt teeth about the middle. Clypeus convex and 

 emarginate. Glossy black ; the clypeus, except the anterior margin 

 narrowly, a Hne on the scape in front, a club-shaped mark between 

 the antennae, the sinus of the eye, a narrow spot behind it, a line 

 along the anterior margin of the pronotum, interrupted in the 

 middle, a marginal band on the basal segment — twice interrupted — 

 and a central spot on margin of second segment, pale yellow. Legs 

 testaceous red, touched with black on the femora. Basal two- 

 thirds of petiole red, apical one-third black ; a shallow longitudinal 

 groove on petiole above, rising about the middle and ending abruptly 

 in a hollow, just before reaching the apex. Wings fusco-hyaline, 

 hind wings paler. Length (to margin of first basal segment) 10 mm. 

 Expanse 20 mm. 



This species can at once be distinguished from its only ally 

 M. impavida by the red on the petiole. 



Taken at Mamadu, Ceylon, April, 1904. 



* Odynerus suhfistulosus, n. sp. Fig. 8. Col. Mus. No. 224. 



This species dififers structurally from typical O. flstulosus in the 



following important respects. The basal three segments as coarsely 



punctured as head and thorax, the apical two segments without 



punctures. Clypeus emarginate, scutellum without a furrow,
