oblique, and the anterior extremity of each is rather narrowed; 

 these dorsal spots occupy the summits of the humps already 

 described ; another series of very similar yellow spots is 

 marginal, occupying the lateral dilatation of each segment, 

 and above this marginal series of yellow spots are the 

 circular and rather conspicuous spiracles ; in the two 

 remaining series the yellow markings are linear and ventral, 

 and equidistant between the claspers and dilated margin. 

 It feeds on various papilionaceous plants, as the species of 

 Lotus (bird's-foot trefoil), Anthyllis (kidney vetch), and Tri- 

 folium (trefoil). On or about the 13th of June these larvae 

 changed to pupae, at the bottom of the glass wherein they 

 were confined, without attaching themselves in the slightest 

 manner to the food-plant or any other substance : the pupa 

 is rounded and entirely without projecting points or angles ; 

 the extremities are remarkably obtuse : it is covered with 

 short hairs, which however are not very apparent without the 

 use of a lens : its colour is a pale, dingy, greenish brown, 

 and the cases which envelope the thoracic segments and 

 wings have a semi-transparent appearance. I am indebted 

 to Mr. Klein for a liberal supply of this interesting larva. 

 The perfect insects appeared on the 6th, 8th and 9th of July.

Contribution towards a Life-History of Lyccena Arion. — 

 Having at length succeeded in obtaining eggs of P. Arion, I 

 am pleased to be able to send you six of them — four on as 

 many sprigs of thyme, and two on another piece. None of 

 them had hatched when I put them into the box this evening, 

 but they will be sure to do so in a day or two, Mr. Buckler 

 having ascertained, from some eggs laid by a female I sent 

 him (taken in cop,), that they hatched in about seven days, 

 and these I now send you have been laid about that time, if 

 not longer. Some others I had have hatched. If you find 

 any egg-shells empty, you will be able to find the yellowish 

 pink larva in the flower. I hope we shall be able to work 

 out the larval life-history of this entomological puzzle this 

 year. I followed a female specimen last Saturday to a fine 

 patch of thyme, where I watched her for a quarter of an hour, 

 and distinctly saw her lay several eggs. Some of these I 

 afterwards took away, and others I left, marking the plant 

 for future observations. I gathered a large number of
