poplars, hazel, shacl-berry, etc., are the species of plants 

 Avhich are most infested. By carefully examining the leaves, 

 specimens may be found feeding and should be kept sepa- 

 rately with a note giving the plant on which they were 

 found as well as the date. Care should also be taken to 

 secure both males and females if possible. 



The males have generally brighter colored heads and 

 often the whole body is brighter and more shining than that 

 of the female, they are also more slender, the under side 

 flatter, and in many species with tufts of hair, or with a 

 o-roove under the thorax and abdomen which is wantinoi: in 

 the female. In mounting the specimens care should be 

 taken to place them in such a position that these characters 

 may be readily seen, also, so that the claws of the tarsi can 

 be examined with a magnifier, as there are differences in 

 the position of the tooth with which each claw is furnished 

 which separates species otherwise almost exactly alike. 

 The males of certain species also have white hairs on the 

 antennae which are easily removed but which are probably 

 of importance in separating closely allied species. 



A carefully collected series, stating the food-plant and 

 time of capture, would be of great importance in determin- 

 ing the limits of species. Other species which are found 

 in similar situations are BracJu/s, which is abundant on oaks. 

 Taj)hrocerus and Pachyscelus are more common on herba- 

 ceous plants, particularly 6 Lgiiminosce.
