 ExixeiMva maguai'i (Gmel.). 



Giebel described a Neophilopteras from this same host, calling- 

 it iV. sabincompletus. But to this species, so far as it is possible 

 to understand it from Giebel's description, the present specimens 

 do not belong. 



Male Reproductive System (text-fig. 13). — Testes pyriform as 

 usual. The ductus is short, there being only two bends in it 

 from the mesosome to the vesicula. The vesicula semincdis is 

 elongate, narrow, with a longitudinal median groove indicating 

 the double origin of this organ. The ductus, on leaving it, 

 bends backwards for a little way, and for this portion of its 

 length the duct is a fairly narrow canal. On tui-ning forwards 

 again after the second bend, it expands into a large canal quite

as broad and long as the vesicula itself, and no doubt functioning 

 as an ejaculatory ampulla, as its walls are well supplied with 

 transverse muscle-fibres, which run in from opposite, sides and 

 appear to become plaited together in the middle. 



Male Gopulatory Apparatus (text-fig. 13). — Basal plate: Longer 

 than the parameres, broader behind than in front, posterior margin 

 very convex. EM,ch lateral mai'gin has a broad band. Between
