1908] New species of Idolothrips 289 



Male. — Larger than female (length about 4.5 mm.). Fore tarsi brownish 

 yellow; fore tibial blackish brown, darker basally. 



Head longer, narrower, and wider across eyes than that of female; genal 

 spines longer and much more prominent; postocular bristles less than half as 

 long as eyes. Eyes larger, more bulging, the head flaring out to receive them. 



Prothorax longer than width of head, less than twice as wide as long; anterior 

 lateral margins broadly and evenly rounded. Inner surface of fore femora 

 without trace of a tubercle; outer surface near apex with a long, stout, down- 

 wardly-hooked spine ; fore tarsi armed each with a very large, stcjut tooth. 



Abdomen slender, tapering evenly from base to tube. Tube .73 as long as 

 head, tapering evenly from base to apex. Segment 9 with a pair of strong, 

 prominent, downwardly-directed, brown spines on its ventral surface. 



Measurements: — Total length 4.52 mm.; head, length .74 mm., width .26 

 mm. ; prothorax, length .35 min., width (including coxfe) .60 mm. ; pterothorax, 

 width .70 mm.; abdomen, width .66 mm.; tube, length .54 mm., width at base 

 .123 mm., at apex .078 mm. Antennae: 1, 73/t; 2, 98j(i; 3-8? 



Described from four females and one male, all from Illinois, 

 as follows: White Heath, Aug. 26, 3 ? 's and i cJ^, on white oak 

 (C. A. Hart) ; Bosky Dell, Oct. 22, 9 , on white oak (L. M. Smith). 



This species is a very distinct one, readily distinguishable 

 from its congeners by the femoral tubercle and tarsal tooth of the 

 female, and by the armature of the ninth abdominal segment of 

 the male. It is the largest known North American species of the 

 order east of the Rockv Mountains. 



Recent Deaths. 



William Harris Ashmead, Honorary Fellow of the Entomo- 

 logical Society of America, died in Washington, D. C, October 

 17th, 1908. Mr. Ashmead has been a tireless worker in entomol- 

 ogy and his name will be permanently connected with the science 

 of American entomology, especially in the Hymenoptera, which 

 was the field of his work for many years. 



James Fletcher, Entomologist of the Central Experimental 

 Farms of the Dominion of Canada, and one of the best known of 

 American entomologists died in Montreal, Canada, November 

 8th, 1908. He has been a fellow and one of the active officers of 

 the Entomological Society of America and one of the strongest 

 friends and an ardent supporter of the Annals.
