to the shortest line from the end of the subcosta to the 

 end of the anal, all of them being approximated rather 

 nearly to the wing-margin, so as to be, as it were, in the 

 circumference of a slightly truncate, elongate, semi- 

 ellipse. Third joint in the q antennae longer than the 

 4th, and bulbose with the base of the bulb in the dried 

 specimen somewhat obconieal, and with a deep, ample, 

 campanulate verticil of hairs ; the succeeding joints to 

 about the 11th also bulbose, with long beaks and cam- 

 panulate verticils ; and then the beaks lessen in length, 

 and the verticils grow wider and shallower ; articular 

 appendages flatly setiform, long and curved cycloidally 

 or subspirally, with the ends returned, as described above 

 under step d". Species No. X, Alg. 



tt E. Bristling hair on the wing wholly interior to the shortest line from the 

 end of the subcosta to the end of l-iie anal nervure. First joint 

 in the $ antennae shorter than the next two together ; 2nd joint 

 subglobular. 



E. First joint in the <? antennae shorter than the 2nd joint. Bristling 

 hair extended shortly beyond the pobrachial bifurcation, 

 and very shortly beyond the radial ; its endings on the 

 radial branches and cubitus in a curve with one another ; 

 subcosta, prsebracliial and anal nervures without bristling 

 hairs ; apex of the wing subacutely pointed between the 

 cubitus and the praebrachial, quite close to the latter nervure. 



e. Endings of the bristling hair on the pobrachial branches and 

 postical nervure arranged in a re-entering angulated 

 line with one another far beyond its ending on the 

 axillar; this last ending, in the ?, distant from the 

 wing-margin Species No. XI, Alg. 



e.e. Endings of the bristling hair on the pobrachial branches and 

 postical nervure, in the S > placed in a direct transverse 

 line with the ending on the axillar ; this last ending 

 close to the wing-margin Species No. XII, Alg. 



E.E. Male unknown. Bristling hair on the pobrachial nervure confined 

 to the stem and not extended to the branches ; its endings 

 on the radial branches, in the ? , subopposite each other, well 

 beyond the bifurcation, but distinctly interior to the ending 

 on the cubitus ; its endings on the pobrachial and postical 

 placed in a direct transverse line with its ending on the 

 axillar ; this last ending placed rather near the wing-margin ; 

 apex of the wing acute, exactly at the end of the praebrachial 

 nervure ...Species No. XIII, Alg.
