by Pr Smith, who states that it has been bred from butternut, hickory 

 and birch. 



Tomoxia bidentata Say 



A narrow, triangular, grayish beetle from }i to >< inch long, occurs on hickory in 

 June. 



This species was obtained in some numbers June 8, from decaying 

 hickory at Albany. It has a very close resemblance to T. 1 i n e e 1 1 a Lee, 

 though the grayish, linear markings are not so distinct. 

 It may be recognized, according to Dr Smith, by the long, 

 triangular last joint of the maxillary palpi, and by the base 

 of the thorax being rounded at the middle. The elytra are 

 marked with broad bands not extending behind the middle, 

 and with the posterior fascia 



larged 



composed of spots, a cinere- 

 ous apical margin and a rhom- ^ 

 boidal dark spot each side, 

 near the base. This species 

 was collected June 29 on dying 

 hickory by Dr Hopkins, and 



Dr Smith records it from various New Jersey localities on dead trees, but 

 nowhere common. Dr John Hamilton states that it is not common in 

 southwestern Pennsylvania about old trees. It was described 

 by Say from Missouri, and Dr Smith lists it from the Middle 

 and Western States. 



Tomoxia lineella Lee. 

 A narrow, triangular, brownish, gray-marked beetle about 3/, 5 to 5/,g 

 inch long, occurs on decaying hickory in early June. 



This rare species was obtained in some numbers from 



a decaying hickory at Poughkeepsie, June 4, 1903. It has 



H^eJi'i"°''en- somewhat variable linear grayish markings on the head and 



larged (onginai) jJ^qj.^,,^ j^p^ ]^^g been rccordcd by Ulke as occurring on old 



twigs in the District of Columbia, and Dr Smith reports it from dead trees.
