12 CIMBEX CONNATA. 



With the darker specimens the thorax is almost en- 

 tirely black, the tibiae are also black or dark fuscous, 

 and the middle of the abdomen on the back and along 

 the sides is violaceous, as in G. decemmaculata, Leach ; 

 with the lighter aberrations the head, pleurae, the 

 breast in part, pronotum, and the edges of the lobes 

 of the mesonotum are brownish-testaceous ; the abdo- 

 men is only violaceous at the base, and on the seventh 

 and eight segments at the sides; the legs too being 

 brownish-testaceous, save the femora, which are always 

 violaceous. 



The distinctions between connata and lutea lie in 

 the darker-coloured thorax and base of the abdomen in 

 the former, which are always for the greater part 

 fuscous, for the ground colour, and most distinctly 

 violaceous, the same being the case with the coxse, 

 trochanters, and femora ; the wings are darker at the 

 median cellule and at the apex, while they have also 

 a more distinctly marked violet iridescence. The pubes- 

 cence on the thorax and base of abdomen is shorter 

 and thinner, the spurs are longer and thinner ; gener- 

 ally too it is a larger insect than lutea. 



The larva is of a beautiful clear green colour. The 

 head is also greenish, with black eye-spots. The dorsal 

 stripe is bluish-black, with paler spots. It commences 

 on the first segment, continues to the penultimate, and 

 is of a uniform breadth throughout. On each side it 

 is bordered by a yellowish line. Not far from this 

 yellow line is a roundish black dot ; the spiracles are 

 also of this colour. On the sides are numerous white 

 warts. 



When young (i. e. before the first moult) the larva 

 is uniformly clear green, the head shining, the spiracles 

 black, and there are on each segment three small black 

 spots, which form three rows of spots, the uppermost 

 being on the head. It feeds on alder. 



Campoplex argentatus, Etz. ; C. holosericeus, Rtz. ; 

 Mesochorus splendidulus, Gr., and Paniscus glaucop- 

 terus, L. are its parasites.
