166 ME. E. m'lachlan on the keueopteka oe 



Eambur, of Soutli Italy and Sardinia, and agrees with it in the 

 simple claws, and also in the general system of coloration, and in 

 form. It is larger, and distinct, especially in consequence of the 

 spots at the base of the anterior wings. It also has affinity with 

 Chrysopa dorsalis, Burmeister. 



Var. ? Smaller. Brighter green. All the markings on the 

 head and thorax only faintly indicated; the pronotum without 

 dark margins, but only with sublateral obscure lines ; the meso- 

 and metanotum with obscure lateral spots. "Wings with the basal 

 spots and colour of reticulation as in the type form ; reticulation 

 open ; only 3 nervules in the inner and 5 in the outer gradate series 

 in the anterior wings ; the partition nervule of the third cubital 

 cellule interstitiate with the nervule above it. 



Expanse 23^ mm. 



One $ taken in company with the type form. I believe this 

 is only a dwarf pale condition of fortunata ; but the point can 

 hardly be decided without further materials and local obser- 

 vation. 



Chrtsopa subcostalis, n. sp. 



Closely allied to G. fortunata. Differs as follows : — The two 

 lines on the crown of the head reduced to dots, or absent alto- 

 gether. The blackish margins of the pronotum very broad, and 

 complete (not enclosing spots of the pale ground-colour) ; on the 

 uieso- and metanotum they are more or less broken up into spots. 

 In the anterior wings the subcosta is conspieuously ilacJc for about 

 half its length from the base, the longitudinal nervures otherwise 

 green ; the rest of the reticulation dusky, not so decidedly blackish 

 &,s in fortunata, and (with the exception of the costal nervules) 

 appearing almost green in certain lights ; basal spots as \n fortu- 

 nata ', but that in the anal area is not indicated, and that on the 

 first postcostal nervule is still more distinct, and the nervule 

 itself much thickened, the spot forming a raised shining black 

 blister; partition nervule of the third cubital cellule rather more 

 extended ; 3 nervules in the inner gradate series, and 5-6 in the 



species"). All that can be said ia its favour is that it is tlie usual condition in a 

 series of species that otherwise agree in general form. But in this same series 

 we find what ought to be a far more important character in the form of the 

 tarsal claws, represented in both conditions, and to an extent tliat, without 

 consideration of it, much confusion is likely to exist (ex. gr. Ch. abbreviata and 

 fkyllochroma).
