TRIBE I. SITOXIXI. 



common than ltixj>i<lnl<i abont New York City. An introduced: 

 European species known as the "yellow clover curculio," which has 

 spread from Newfoundland and New England, west and north to 

 Iowa and Minnesota. LeConte, in ISKi. recorded it as abundant 

 near the seashore in the Atlantic states. In England it is very in- 

 jurious to clover. Webster first recorded it from Indiana (1886, 

 580) as being abundant and injurious to white and alsike clovers 

 on the grounds of Purdue University at Lafayette. He states 

 chat the beetle eats through the back of a folded clover leaf at 

 the midvein, thus forming a circular disk when the leaf is un- 

 folded. They also often eat a hemispherical portion from the 

 margin, and if from the same leaf, this leaves only the leaf stalk 

 and bases of the midveins. The larvae live on the clover-roots 

 and pupate in a small earthen cell. Both adults and larva: 1 hiber- 

 nate, the latter pupating in spring, the pupal stage lasting about 

 20 days. The adults seem to wander about in early spring, and 

 Webster says that he has often seen them upon the heads of grain, 

 traveling along upon fences and the trunks of trees and hiding 

 away under rubbish. 



181 (8348). SITOXA TIBIALIS Hbst, 1795, 217. 



Elongate-oblong. Black, rather sparsely clothed with small oval or 

 rounded grayish and brown or brassy scales, the latter forming a rather 

 broad sutural and a marginal stripe each side of elytra; antennae and legs 

 reddish-brown, apical halves of femora darker. Beak and head longer 

 than thorax, coarsely and sparsely punctate, the frontal groove very dis- 

 tinct. Thorax as in flavescens, the punctures of disc rather coarse and 

 sparse. Elytra one-half wider at base than thorax; disc distinctly striate, 

 the strial punctures small; intervals moderately convex, each with a row 

 of very short setae. Length 3.5 4.5 mm.

 and New Mexico. LeConte states that it was probably intro- 

 duced from Europe in earth around roots of shrubs and trees. In 

 addition to the above named species (all that Ave are able to rec- 

 ognize in the Eastern material before ns), there are references in 

 literature to the following:
