HYMENOPTEROUS FAMII.Y STEPHANID^.. 729 



carinate ; femora smooth and pilose, with two very long and 

 slender teeth ; tibiae constricted in basal third and again beyond 

 middle. 



Black ; a white spot on cheeks ; base of flagellum ferruginous ; 

 anterior legs, hind trochanters, constricted part of tibiae, their 

 apex, and the hind tarsi fulvous. Wings slightly infumate, 

 external submedian cell darker, with a pale space beyond it. 



Length 26 mm,; abdomen 16 mm,; petiole 8 mm.; terebra 

 27 mm. 



The type, in the British Museum, bears a label " Austi-alia, 

 1868 "only. 



The cotype, in same collection, is much smaller : body 20^ mm. ; 

 abdomen 13 mm.; petiole 6 mm.; terebra 19 mm. It was taken 

 by F, P. Dodd, 5. iii. 08, at Townsville, Queensland.

§ . Face below antennae obliquely striate, the striae descending 

 from the sides to the central line ; frons transrugose ; vertex 

 coarsely transrugose ; occiput with a small central part trans- 

 rugose, laterally ii'regularly reticulate. Neck elongate, trans- 

 rugose; mesonotum apically smooth, centrally diffusely punctate 

 with a few transrugosities ; scutellum smooth, with deep and 

 coarse but diffuse punctures ; median segment scrobiculate 

 reticulate. Abdomen slightly pubescent ; petiole trans-striate, 

 Terebra as long as body, white-banded before apex. Hind coxae 

 trans-striate ; hind femora bidentate. 



Black ; head except apex of mandibles, scape, sometimes also 

 basal flagellar joint, apex of pronotum, anterior femora, tibiae 

 mostly, and the tarsi red ; antennae fusco-piceous. Wings in- 

 fumate, nervures fuscous or rufo-fuscous. 



Length 38 mm. Expanse of fore wings 18 mm. 



c? . Similar to 5 ; head more strongly transrugose, occiput 

 centrally more broadly trans-striate, metathorax more rugose, 

 petiole and coxae more finely sculptured, serrations on hind 

 femora finer ; abdomen fusco-piceous. 



Length 24 mm. Expanse of fore wings 11 mm. 



Habitat : Manila, Philippines ; Bachian, Molucca Islands. 



Schletterer (I. c.) tentatively synonymizes this with M. tarsalis 

 Smith, from Bachian, remarking that it corresponds in the 

 infumation of the wings, length and colour of terebra, colour of 

 body, sculpture of petiole, and, to some extent also, in sculpture 

 of head and thorax. It appears, however, to differ in having the 

 head coarsely sculptured, black, not red as in tarsatus, the thorax 

 coarsely punctate, and is only 9 lines (18 mm.) long. I consider 

 it a distinct species, but the- description is insufficient for certain 

 determination.
