dant, it may be readily controlled by gathering the infested twigs

1838, 42. 



Elongate, very slender, subcylindrical. Uniform light reddish-brown, 

 very sparsely pubescent. Joints 3 and 4 of antennae each with a short spine 

 at apex. Thorax cylindrical, nearly one-half longer than broad, sparsely 

 and irregularly punctate. Elytra deeply and rather closely punctured, the 

 tips each with a short spine on outer side. Length 8-12 mm. 



Throughout the State: scarce. June 1-July 29. Occurs about 

 red-bud and wild plum, in the twigs of which the larvae dwell ; also 

 taken at light. 



XVI. Tylonotus Hald. 1847. (Gr., " a knot + back. ") 



This genus is represented in the eastern United States and Indi- 

 ana by a single medium-sized species having the femora strongly 

 clubbed ; antennae as long as body, compressed and with two grooves 

 or sulci on the outer side, these more noticeable on the third and 

 fourth joints. 



1898 (6079). Tylonotus bimaculatus Hald., Trans. Amer. Phil. Soc, X,

Elongate, rather robust, subdepressed. Dark brown or piceous ; elytra 

 each with two rather large, somewhat rounded yellow spots, one near mid-

 raised spaces smooth. Elytra coarsely and rather sparsely punctured, not 

 spined at tip. Length 12-16 mm. 



Putnam County; rare. July 8. The larva? bore in ash wood 

 and the adults usually occur about these trees.

 lated ; femora strongly clubbed ; antennae of female slender ; of male
