EUTHRIPS FUSCUS Hinds. 



On a slide in the collection of the United States Department of 

 Agriculture were found five females and one male of this species. 

 The data on the slide is as follows: ''Thrips on timothy, from J. H. 

 Comstock, July 6, /73." Since the male of this species has never 

 been noted, a brief description and comparison with the female is 

 here given. 



Male. — ^Newly discovered. Length 0.75 mm. Antennae shaded 

 as in Hinds's description, though lighter throughout. Apterous. 

 Color of body light yellowish brown. (The color of the abdomens 

 of the females on the slide is deep brown.) Comparative measure- 

 ments of the antemise both of the females and the male on the Com- 

 stock slide are as follows: 



The ninth segment of abdomen apically bears a circlet of eight con- 

 spicuous spines. Of these the four that are borne ventrally are the 

 smallest and lightest in color, and do not quite reach the tip of the 

 tenth segment. Dorsally near each lateral margin stands a very long, 

 strong, dark-brown spine, wliich is about twice the length of the 

 ventral spines. The two remaining spines stand one on each side 

 midway between the meson and the spines near the lateral margin^
