 Sciara hartii n. sp. 



Mr. Chas. A. Hart recently records (Forbes, 15th Rept. State Ent. 

 111., pp. 95-98) a species of Sciara seriously injurious to cucumbers 

 in forcing houses. At my request Mr. Hart kindly sent me a number 

 of specimens taken at Morrison, 111. These proved to differ from any 

 of the species noted on the previous pages. This species somewhat re- 

 sembles S. cucumeris but is more closely related to S. fatigans from 

 which it differs in having a wider wing, broader cell Ri, Rs less 

 curved, ending a little more distad. The hypopygium differs in having 

 apical hairs on the clasper more dense but apparently lacking the 2 

 smaller apical setse. Alcoholic specimens are dusky yellow, but in 

 life they are probably more or less fuscous. Antennae of the male about 

 3^ the length of the body. Length (in alcohol) about 1.5 mm. One 

 male and many female specimens. This species will find a place in the 

 key with S. fatigans from which it may be distinguished by its venation. 



Quite recently a new genus belonging to the Mycetophilince has been 

 described by Landrock (Wien. Ent. Zeit. XXX. 161 ) represented by an 

 European species. It will fall in with Neuratclia in the dichotomic 

 table in Genera Insectorum (Ease. 93). It may be distinguished from 

 that genus by the strongly produced costa and the absence of one of the 

 anal veins. 



The generic name Meunieria proposed by me (Genera Insectorum, 

 Ease. 93, p. 87.) must be changed. It is already twice preoccupied.
