feed on the bark and petioles of the leaves at the ends of the 

 shoots. Mr Tolman found them pairing in Jinie on a fallen 

 hickory near Philadelphia. We have bred this species from 

 hickory stems in which the larvae lived at the juncture of the 

 dead and living bark. Mr S. T. Kemp records the fact that he 

 found the larvae of this species inhabiting the base of dead shoots 

 of hickory, and, on breaking off the shoots, the borers were 

 almost entirely exposed, sometimes falling to the ground. The 

 infested shoots were invariably those which had been broken off 

 3 or 4 feet above the ground by the larvae of E 1 a p h i d i o n 

 V i 1 1 o s u m Fabr. the previous season. The grubs of these 

 work at the very base of the tree and burrow almost laterally 

 and slightly upward. In addition to food plants mentioned 

 above, Dr Packard records breeding the species from alder, but 

 this appears to be exceptional. 



Description [pi. 7, fig. 8]. Black, sometimes brownish black, 

 coarsely punctured and covered with brownish black pubescence 

 above and gray below. Antennae black; thorax with two black 

 spots below, a lateral orange red band that extends on the head 

 to the eyes and joins at the apex; the elytra have a submarginal 

 band that connects with the thoracic one at the humeral angle 

 and at the rounded apex joins a sutural band, wdiich is some- 

 times wanting. This species is remarkable in that the male pos- 

 sesses a tooth or process on all its claws. 



Connecta n. var. [pi. 7, fig. 9]. Like the species in color but 

 lacks the sutural line; the submarginal band extends to the 

 margin; and it has three oblique lines on the elytra, the apical 

 one rudimentary and the middle one broad. Dr Fitch has de- 

 scribed two varieties, abbreviata and s u t u r a 1 i s , which 

 are characterized simply on the width of the sutural and sub- 

 marginal stripe. Types in the collection of L. H. Joutel. 



The variety connecta is connected with the species by 

 intermediate forms in all stages of development, from those that 

 have a slight mark at the marginal band or at the sutural one or 

 both, to those that have the two bands in various stages of 

 development [fig. 6].
