y^G REPORT OF NEW JERSEY STATE MUSEUM. 



pare the systematic part of this list, and by Dr. B. P. Felt, State Ento- 

 mologist of New York, and a great many new species have been desci'ibed, 

 some of which will undoubtedly be found in New Jersey. Mr. Beuten- 

 muller has in general included only actual records, mostly of his own col- 

 lecting, and the notes on food plants, etc., are his, unless otherwise 

 credited. In some cases galls have been described, of which the makers 

 are yet unknown, and these are separately listed. Dr. Felt has kindly 

 supplied additional notes from his breedings and studies, but I have not 

 been able to incorporate all his systematic suggestions. 



As the species differ so widely in habit, so the methods of dealing with 

 them are diverse. Insecticides are available in the smallest number of 

 cases, and usually it is some change in cultural method that must be 

 relied upon to prevent injury. 



LASIOPTERA Meigen. 



L. carbonifera Felt. Makes galls on leaves of goldenrod; common and 



g. d. (Bt). The gall was first desciibed by Osten Sacken, and the 



name is so credited in the last edition. 

 L. cornicola Beut. Ft. Lee district. Galls on trunks and branches of 



dogwood, "Cornus stolonifera" IX-VI (Bt) ; Staten Island (Ds). 

 L. cylindrigallae Felt. Ft. Lee district IV, V (Bt); Staten Island, gall 



elongate on stems of goldenrod IV (Ft). 

 L. farinosa O. S. Throughout the State, locally common, galls on leaves 



of blackberry, "Rubus villosus" VIII-X (Bt). See in this connection 



"L. nodulosa" Beut. 

 L. humulicaulis Felt. New Jersey district (Bt) ; gall on stem of hop (Ft). 

 L. linderae Beut. Ft. Lee district and elsewhere, sometimes common; 



galls on branches of spice bush, "Lindera benzoin" X-VI (Bt) ; Staten 



Island, from irregular sub-cortical gall. 

 L. lycopi Felt. Plainfield; gall on bugleweed "Lycopus virginicus" IX-V 



(Bt). 

 L. nodulosa Beut. Ft. Lee district; galls on branches of blackberry, 



"Rubus villosus" X-VI (Bt). This is the species referred to in the 



last edition as "farinosa." I have found it, locally, from New Bruns- 

 wick southward; sometimes also on dewberry, but never causing 



actual injury in cultivated fields. 

 L. sambuci Felt. Ft. Lee district; galls on stems of elder, "Sambucus 



canadensis" IX-VI (Bt) ; Staten Island (Ds). 

 L. solidaginis O. S. New Jersey district; larva probably inquilinous in 



galls on Solidago (Bt). 

 L. tumifica Beut. Ft. Lee district; gall on stalk of golden-rod, "Solidago 



rugosa" IX-VI (Bt) ; Staten Island, from eccentric sub-globular stem 



gall (Ft). 

 L. vernoniae Beut. Ft. Lee district and elsewhere; galls on leaves of 



ironweed, "Vernonia noveboracensis" IX (Bt) ; Staten Island IX (Ds).
