 and one third times longer than wide.

As already implied, there is no possibility of confusing this species with guapo. 

 In addition to the differences given above, typhon has the stigma shorter, wider and 

 less narrowed apically (cf. Text-fig. 240) ; the punctation of the temples and 

 occipital region is denser, less coarse and with the surface duller than in guapo.

Type-species : Snellenius vollenhovii Westwood. 



Muesebeck (1931) was the first to place this genus in the Microgasterinae and to 

 point out its relationship with Microplitis. I have no hesitation in supporting his 

 conclusions and consider Snellenius to be more closely related to Microplitis than to 

 any other genus of the Microgasterinae. Indeed, I have not been able to find a sharp 

 line of division between the two genera. The differences given in the key seem to be 

 the only ones of value. 



Key to Species 

 Females 



1 Disc of scutellum reduced to a small, blunt, erect cone ; flagellar segments very 



strongly flattened, the middle segments slightly wider than long. 



Virtually black species with the gaster whitish-yellow to sides of tergites 1 and 2 ; 

 sides of thorax dusky red ; wings dark brown with a hyaline spot just proximal to 

 the areolet ; radial cell narrower than in any other species of the genus ; 2nd trans- 

 verse cubitus meeting the radius virtually at junction of radius and 1st transverse 

 cubitus ; tergite 1 about three and a half times as long as wide, smoothly hollowed 

 out like a trough almost to apex ; length: ca. 8 mm. . vollenhovii Westwood 66 



New Guinea. 1 ^ 1 ? in British Museum (Nat. Hist.). 

 - Disc of scutellum without such a cone, flattened, with deep excavations and strong, 

 lateral margin (less strong and less characteristic in theretrae) ; flagellar segments 

 never as flattened as this and the middle segments seen at their flattest always 

 considerably longer than wide ......... 2 



2 Thorax predominantly bright fulvous, only the propodeum and metapleurum being 



somewhat infuscate ; notaulices shallow, poorly defined and without rugosity ; 

 middle lobe of the mesoscutum hardly raised as a shield. 



Head blackish ; gaster blackish in apical half but extensively whitish-yellow 

 beneath and to sides of tergites 1 and 2 and across apex of 3 ; fore wing in greater 

 part brownish but with the median cell hyaline in the single $ but brownish in the 

 two (Jo* examined ; a darker cloud beneath the stigma in both sexes is flanked by 

 paler subhyaline areas ; 2nd transverse cubitus meeting the radius far distal to the 

 junction of the radius and the 1st transverse cubitus, the areolet hence large
