302 STATES OF INSECTS. 



Linne, with red elytra, is the female of his L. testacea, 

 in which they are testaceous. Canlharis dermestoides of 

 the same author is the other sex of his Meloe Marci ; 

 one of which is chiefly testaceous, and the other black : 

 which seems to have so misled Linne, that he placed 

 them in different genera. One more instance in this 

 order, the female of Cicindela campestris, as was first ob- 

 served to me by our friend Sheppard, has a black dot on 

 each elytrum, not far from its base near the suture, which 

 the male has not. 



Amongst the Orthoptera, the male Locusta F., as Pro- 

 fessor Lichtenstein has informed us a , have a fenestrated 

 ocellus, which is not to be found in the other sex. I was 

 once attending to the proceedings of a Hemipterous spe- 

 cies, Pentatoma oleracea Latr., which I found in union : 

 the paired insects had white spots, but another individual 

 was standing by them, in which the spots were of a san- 

 guine hue. I mention this by the way only — the spots 

 in the prolific sexes being of the same colour : but might 

 not the red spotted one be a neuter ? 



The sexes of many Lepidoptera likewise differ in their 

 colour. I must single out a few from a great number of 

 instances. The males of Lycoena Argus F. have the up- 

 per surface of their anterior wings of a dark blue, while 

 in the female it is wholly brown. The wings of the for- 

 mer sex of Hypogymna dispar are gray, clouded with 

 brown ; but those of the latter are white, with black 

 spots. In the brimstone butterfly (Colias Rhamni), which 

 is one of the first that appear in the spring, the wings of 

 the male are yellow— of the female whitish. In the com-
