Cameron gives eight, but. ais has been said above, his Fenusa includes 

 the species referred by Konow to Kaliosysphinga. My two are 

 pygmcea, KI. (from coll. Caproii), and nigricans, Kl. (== befulce, C, .), 

 given to me by Mr. McLachlan. See the Table following. 



Fenella, Westw. 



I have several specimens of one species, which has been deter- 

 mined for nie by Ilerr Konow as nigrita. Fenella westwoodi, C, is 

 unluiown to me, and Konovi^ has remarked that the description does 

 not show why the author refers it to Fenella ratber than to Fenusa. 



The above four genera, though amply distinguished by the 

 characters pointed out by Konow, consist of species which are super- 

 ficially very similar, and I believe it will be most convenient for my 

 readers if I tabulate such of the insects included in tlitm as are 

 known to me together. They are all very small and dark insects, 

 with black bodies, and a length which seldom exceeds and otten falls 

 considerably short of 3 mill. Most, if not all, are leaf-miners ; and 1 

 believe they are generally pretty common, though 1 have not often 

 come across them in my own collecting — i)robably because I hardly 

 ever "sweep." All the species tabulated have been determined for 

 me by Herr Konow ; so that, though my list is no doubt very im- 

 perfect, it can be relied upon as accurate so far as it goes. 



SYNOPTIC TABLE OF BRITISH PSEUDODINEURA, FENUSA, &c. 



1. Ilind-wing with t.\o closed cells (cubiUl and medial), but no " huuiorus " 



(genus Pseudodineura, Knw.). Tlie only species known to me for certain as 

 British is Pseudodineura fuxcula, Kl. 



— Ilind-wing with no closed cubital or medial cell 2. 



2. Ilind-wing without humerus. Fore-wing with humerus approaching so closely 



to the brachius that the humeral area, though really " petiolate," appears 

 " contracted " (genus Kaliosysphinga, Tischb.) 3. 



— Hind-wing with humerus. Fore-wing with its humeral area simply " petiolate," 



no appearance of being " contracted " ^• 



3. Radial n. received in front of the second cubital n... Kal. uiiiii, Sundw, 



— Radial n. received beyond the second cubital n 4. 



4. Fourth antennal joint scarcely longer and a little thinner than the second, the 



third longer by quite a half than the fourth A', dohrni, Tischb. 



-• Fourth antennal joint evidently longer and almost thicker than the second, the 

 third hardly longer by a half than the fourth. A slightly larger species than 

 the last, and with darker wings -^- melanopoda, Cam. 



5. Antennsewith more than 10 joints ..Fenella niffrita, Westw. 



— Antennae with 9 or 10 joints (genus Fenusa, lieacli) 6. 



6. Smaller. Legs white and black, with black hind femora F. pygmxa, Kl. 



— Larger. Legs, including the hind femora, yellowish F. nigricans, Kl.
