ENTOMOLOGICAL NEWS. 



[Nov., '03 



During the spring of 1903 it has made its appearance on a 

 few trees at Amherst (seven miles from Northampton), but 

 no reports of its presence elsewhere have been received. When 

 abundant, it may become a very serious pest to the plum- 

 grower, as the trees attacked are defoliated just at the time 

 when all their energy should be centered in the formation of 

 the fruit. 



This cut shows the structure of the musical apparatus of the male 

 and the ovipositor of the female of Falcicula, a new genus of Gryllidse 

 described on page 258 of the Oct. News. The species is hebardi, found 

 by Mr. Morgan Hebard at Thomasville, Georgia. 



DiXA CLAVULUS Wllliston — Diptera of St. Vincent, Trans. Ent. Soc. 

 London, '96. — In a paper which recently appeared in the New York 

 State Museum, Bulletin 68, p. 429, a description is given of a fly under 

 the name of Di:ra modesta. Unfortunately, in drawing up this descrip- 

 tion, Professor Williston's species was overlooked, and hence it was re- 

 described under another name. 



Upon examination it will be seen that the two descriptions are quite 

 similar, and I have also compared my specimens with a co-type of Wil- 

 liston's species collected by Mr. H. H. Smith, now ia the Cornell Uni- 

 versity Collection and find them identical. 



In fresh and in immature specimens the colors are paler or more yel- 

 lowish than in mature, dried specimens. The* rostrum in some speci- 

 mens is dusky, in others paler. These paler specimens will find a place 

 in the key given (p. 431 1. c. ) in the second couplet with marginata, from 

 which they may be distinguished by their dark thoracic stripes. The 

 knob of the haltere is dusky.
