SUCCESS TO ENTOMOLOGY, 89 



They exhibit all the tendencies to variation which occur in the two 

 species, I do not think 0. dilutata and 0. christyi ever pair in a state 

 of nature. In the few doubtful specimens which I have taken at large, 

 the difficulty in determining the species has seemed to be due merely 

 to their bad condition, I have failed in a few attempts to pair (). 

 christyi and 0. autumnata. 



Truinpet=hairs on the pupa of Chrysophanus virgaureae var. 

 miegii {with plate). 

 By De. T. a. chapman. 

 These figures of the hairs of Chrysophanus virgaureae are from a 

 pupa of the var. miegii, reared from the egg by Mr. Hugh Main, from 

 eggs I brought from Spain. The special hairs might, most properly, 

 in this instance, be called " umbrella " hairs. They are, as usual, 

 most numerous near the spiracles and towards the latter segments, but 

 appear to exist over most of the abdominal region. The photograph by 

 Mr, F. N, Clark is from the pupa, undisturbed, and the hairs, taken in 

 profile without any squeezing, twisting, or distortion from mounting 

 in any way. It shows well the long narrow pedicel and the flat 

 umbrella-like top. The form, like an umbrella or mushroom, seems 

 to include a lower surface spreading out from the stalk, and a separate 

 dome-like top, the latter studded with raised points, but I have 

 considerable doubt whether this is so, and I think the top is really 

 centrally depressed, and that it is, in fact, merely the upper side of what, 

 on the other view of the structure, I have called the lower surface. 

 They appear to be 0-06mm, in height, and nearly the same in diameter. 

 The other figure is from a drawing from a specimen mounted on a 

 slide, the whole of the difl'erence between the two figures is not due to 

 distortion in mounting, but hairs were selected for drawing, which 

 showed more variation in size and outline. They show better than the 

 other figures, the form and distribution of the surface spicules, and 

 also confirm the idea that the structure is really of " trumpet " form, 

 and that there is no top apart from the expansion of the sides of the 

 hair. The drawing shows the relation, or rather want of relation, of 

 the origin of the hairs to the fine network of ribbing, and the knobs at 

 their points of intersection already noted in other species. 



Success to Entomology.'' 



Before actually dealing with the subject of the toast I should like to 

 ask the members of the Leicestershire Society two questions, (1) What 

 has entomology done for you since I was last in Leicester ? (2) What 

 have you done for entomology ? I take it that entomology has done 

 much for you, that it has taken you out of yourselves, made you happier 

 men, that it has been the medicine that has taken ofi^ the hurry and 

 worry of everyday life, that it has provided the mental food that has 

 satisfied and balanced your physical state, for we have it on excellent 

 authority that " man doth not live by bread alone," that, in short, you
