2nd. Some individuals develop before winter, hibernating as beetles 

 without leaving the bark, coming forth in early spring ; others hibernate 

 as pupae or larvte, changing to beetles later in the season. 



3rd. That the beetles may be obtained from October to June by 

 judiciously chopping the bark. 



The characters separating Cyrtophorus and Microclytus were originally 

 feeble, and have recently become more so by some one (the record has 

 escaped me) discovering that the relative length of the antennal joints in 

 the male of the latter are the same as in the former, thus leaving in the 

 males only the presence or absence of a small spine at the end of the 

 third joint of the antennse as diagnostic. This discovery was made 

 subsequent to Mr. Leng's synopsis of this genus in Entomol. Americana, 

 III., 23. 



Anthophilax malachiticus Hald. This species occurs here rarely, 

 and my specimens, male and female, I owe to the kindness of Professor 

 Schmitt, of St Vincent, who takes it on chestnut blossoms. The male 

 and female differ in form and perhaps in colour, though the scarcity of 

 examples renders this uncertain. The male is the more elongate, with 

 elytra suddenly narrowed behind the prominent humeri, then scarcely 

 perceptibly so to near tip, which is rounded. In the example before me 

 the head and thorax are bright coppery bronze, the elytra lustrous dark 

 greenish, the underside greenish and bluish black, the legs are rufous 

 with the knees, tibiae and tarsi more or less infuscate. The female is 

 broader, the elytra not so much narrowed behind the humeri and nearly 

 parallel behind the constriction ; the head, thorax and elytra are 

 *' splendent green " ; the underside is darker and obscured by the 

 vestiture, the legs are coloured as in the male ; both sexes have the last 

 ventral segment broadly rounded, and the head, thorax and underside 

 clothed with fine, soft, whitish hairs, longer and sparser on the thorax. 

 The male belonging to malachiticus has not, so far as I know, been 

 described, and the above from only the single individual before me is 

 not likely to apply to all others. A series from different parts of the 

 country, from what occurs in other similarly coloured species, may be 

 expected to yield specimens in both sexes varying from coppery bronze 

 to green, blue or violet, and with legs from black to rufous. Ste7mra 

 cyanea Hald. from Lake Superior seems to be only a greenish blue 

 example, and A. viridis Lee. from the same region with the legs black, 

 though the base of the tibiae is rufous, merely a colour variation. These
