species of Tabanus. The egg mass (Plate 1, Fig. 7) is yellow in the 

 original and not very convex in structure. The young larva (Plate 

 5, Fig. 76, a), is whitish and semitransparent. The full grown larva 

 (Plate 5, Fig. 76, b) is yellow, its natural size 47 mm. The pupa is 

 yellow in color, the thorax grayish (Plate 12, Fig. 139). The hymen- 

 op terous parasite figured (Plate 5, Fig. 76, c) is the only parasite 

 of this (ichneumonid) type observed so far as a tabanid parasite, 

 the other being cases of Proctotrupidae. 



Tabanus sp. No. 14. — Only the pupa of this Indian species (no 

 name given) is figured by Maxwell-Leffroy and Howlett (1909) (Plate 

 11, Fig. 132). 



Eggs and young larvae described by Lutz (1914) of an unknown 

 Brazilian species which he supposes may belong to the tabanids, 

 probably belong to a leptid species.
