The head was ol a deep shining black color, as were the pro-legs. 

 The anal legs were black above, lighter below. The bod) dorsally and 

 sub-dorsal ly was covered with hairs which were dee]) shining black, 

 though duller in color near base. Laterally, on each segmerit, was a 

 spot of light tawny or reddish brown hairs, including in part at least the 

 spiracles, and these, often confluent, formed a lateral band. The spiracles 

 were black. The first larva made cocoon, which was loosely composed 

 of hairs, with little or no silk, July 17th. Unfortunately the pupa? all 

 dried up, so that not one emerged. As will be seen the insect is un- 

 doubtedly double brooded, and passes the winter like its congeners in 

 the pupal stair. 



But there is one item of interest; Mr. Bruce has also raised the 

 larva, and noted the same thing. The larva is, after the first moult, 

 black and the hairs are even and comparatively short. The larva? are in 

 appearance and vestiture not at all like the larvae ofvirgmica or latipenm's, 

 but like, and indeed hardly to be distinguished from the larvae of Arctia 

 virgo, nais, and arge. In other words, the imago is a Spiloso?na, the 

 larva is an Ardia. Whether this will be of value in generic reference, 

 and what effect it will have on the validity of two genera which have now, 

 so far as is known, only the color of the insects to separate them, I will 

 leave to others to determine. 



On some species of Anthaxia. 

 By C. H. Roberts. 



In the Trans. Amer. Ent. Society, Vol. X, August 1882, Dr. Horn 

 has given us a revision of the genus Anthaxia of Bupresticke. 



In his opening remarks Dr. Horn speaks as follows: "In the study 

 of our species I have been unable to find any sexual characters like those 

 which have been observed in the species of Europe. On the other hand, 

 with an incomplete series however, I have not been able to find any of 

 the latter with the tarsal claws toothed as in our cyanella and quercata. It 

 will be observed that these two species differ from each other in the same 

 manner that viridifrons and viridhornis do, and the question has arisen 

 in my mind whether they are not respectively sexes of each other, the 

 male in each case having the rougher surface sculpture." 



Dr. Horn again calls attention to this matter further on in his 

 article, and urges collectors to study the habits of these species, saying 

 of cyanella and qtwrcaia, "they are so often sent together, and even plac- 

 ed side by side, that I am inclined to suspect a closer relationship than 

 diat of allied species, in other words may they not be sexes of oner"
