male of the former is very easily distinguished from that of the 

 latter by the area of the centre eyes being a little, though very 

 inconsiderably, broader before than behind, which is not the case 

 in IS. pygmcea 6. The colour also is quite different in «S. Herii 3: 

 the abdomen has a longitudinal reddish yellow centre band, the 

 cephalothorax is brownish or reddish yellow, often (in both sexes) 

 with the pars cephalica black (var. nigrifrons). For further parti- 

 culars respecting 5. Herii and 5. pygmcea, vid. sup., p. 26. — Dr 

 L. Koch has kindly sent me adult examples of both sexes both of S. 

 Herii (Hahn) and of S. trifasciata C. Koch (= «S. pygmcea (Sund.)). 



Ausserer states that in both $ and $ of S. Herii the eyes form 

 a trapezium, whereas in the female of S. nigrifrons (the male of 

 which is unknown- to him) they form a rectangle. This difference 

 between the females of the two forms 1 am not able to confirm : the 

 area of the centre eyes in both appears to me as nearly as may be 

 rectangular, only a hair's-breadth broader before than behind. 



In the valuable view of the European species of the genus Shiga 

 which Ausserer loc. cit. has published, he enumerates the following 

 species: S. hamata (Clerck), S. nitidula C. Koch, S. semiatra L. 

 Koch (= Ep. lucina Sav. et Aud. ?), S. laurce Sim., S. Herii (Hahn), 

 S. amoena (Blackw.), S. sanguinea C. Koch, 8. albovittata Westr. , 

 S. pygmcea (Sund.), "aS. anthracina C. Koch" (<S. Aussereri Thor.) and 

 S. nigrifrons C. Koch. Concerning S. nitidula Ausserer himself says, 

 that , in consequence of the many transition-forms between it and S. 

 hamata, the independence of the species is very uncertain. As I have 

 already intimated, I cannot in S. nigrifrons see any thing but a va- 

 riety of *S. Herii. The rest are doubtless all good species.
