HYMENOPTEROUS FAMILY STEPHANID^. 757 



of abdomen, which is smooth . Hind legs with coxse closely ti'ans- 

 striate, femora smooth and bidentate; tibise constricted to beyond 

 middle in $ , not quite so far in S . Terebra in § longer than 

 body. 



2 . Black ; head rufo-testaceous, outer orbits broadly white, 

 propleurce and pi'osternum rufous, base of second segment and 

 the anterior legs rufo-testaceous ; middle tibite basally broadly, 

 apically narrowly white; hind legs black. Front tarsi partly, 

 middle tarsi entirely, and hind metatarsus except at apex white. 



c? . Similar to $, but head darker red, face and oral region 

 pale ; prothorax entirely red, basal antennal joints paler, anterior 

 legs testaceous, femora darker, hind legs black with knees rufous, 

 constricted part of tibise and all tarsi white. Wings, in both 

 sexes, hyaline, nervures and stigma rufous in 5 , darker, with 

 pale base to stigma in S • 



Length, $ , 6 mm. ; abdomen 3| mm. ; petiole 2 mm. ; terebra 

 9 mm. Length, S , 7 mm. ; abdomen 3| mm. ; petiole 2 mm. 



There is no doubt that the two species of Cameron are 6 and 

 $ of the same. His statement that the hind femora of M. rvfi- 

 collis are trans-striate is an evident mistake for coxfe. There are 

 few things more deceptive than the relative proportions of petiole 

 and rest of abdomen. Cameron gives the petiole in this species as 

 "twice longer"; the actual measurements are 2 and \\ mm.

S . Frons strongly arcuate striate, vertex and occiput trans- 

 striate, posterior frontal tubercles subobsolete, two carinas between 

 the posterior ocelli ; posterior margin of head bordered. Scape 

 longer than cheeks ; second flagellar joint one and a half times as 

 long as first ; third rather longer than second. Pronotum trans- 

 striate, the extreme base smooth, neck shoi't ; mesonotum finely 

 punctate ; scutellum normal ; propleurse obliquely striate ; meso- 

 pleurse smooth ; metapleuras coarsely punctate and separated by a 

 sulcus from the closely and finely punctate median segment. 

 Petiole finely trans-striate, as long as rest of abdomen, which is 

 smooth and shining. Hind coxse coarsely, their femora finely 

 trans-striate, the latter somewhat strongly infiated, bidentate; 

 tibiae compressed to a little beyond middle. 



Black ; head dark red, antennse pale rufescent, becoming 

 gradually darker towards the apex ; extreme base of pronotum, 

 front legs, middle tibiae and tarsi, hind tarsi, and base of second 

 segment rufescent. There is a scarcely noticeable paler line 

 under the eyes. Wings hyaline, slightly iridescent; stigma 

 rufescent, basally pale ; nervures blackish. 



Length 8 mm. ; abdomen 5 mm. ; petiole 2| mm.
