apically a pair of short, tapering, narrowly rounded, thickly setose lobes. Type 

 Cecid. 1763. 



Bremia sylvestris new species. 



The male described below was taken September 15, 1917, at Keene 

 Valley, N. Y., by Mr. Howard Notman. It is related to B. borealis 

 Felt, from which it is most easily separated by the yellowish and dark 

 brown abdomen and the markedly shorter basal portion of the stem. 



Male. — Length 1.5 mm. Antennae twice the length of the body, thickly 

 haired, dark brown, 14 segments, the fifth having stems with a length 3 and 

 i,Y2 times their diameters respectively. Terminal segment with a length six 

 times its diameter, the distal part of the stem slender and with a length 5 times 

 its diameter. Palpi : indistinct in the preparation. Mesonotum yellowish 

 brown. Scutellum, postscutellum and basal abdominal segments yellowish, the 

 third and following dark brown. Halteres yellowish basally, fuscous apically. 

 Coxae and femora basally fuscous yellowish, the distal portion of femora and 

 tibiae dark straw, the tarsi darker. Claws short, stout, strongly curved, the 

 pulvilli rudimentary. Genitalia : basal clasp segment moderately short, stout, 

 terminal clasp segment rather long, stout ; dorsal plate long, broad, divided, the 

 lobes tapering to a narrowly rounded apex, thickly clothed with short setae ; 

 ventral plate moderately long, broad, deeply and triangularly emarginate, the 

 rather broad lobes narrowly rounded. Style moderately short, stout. Type 

 Cecid. 1746. 



Lobodiplosis borealis new species. 



This interesting male was taken at Keene Valley, N. Y., Septem- 

 ber 4, 1917, by Mr. Howard Notman. It is easily distinguished from 

 L. acerina Felt by the subapical position of the broadly rounded lobe 

 on the basal clasp segment. 



Male. — Length .9 mm. Antennae twice the length of the body, thickly 

 haired, reddish brown, 14 segments, the fifth having stems with a length 2 

 and 2^/2 times their diameters respectively. Terminal segment produced, the 

 basal portion of the stem with a length about four times its diameter, the dis- 

 tal part somewhat produced and irregularly fusiform. Palpi : first segment 

 irregular, the second a little longer, more slender, the third a little longer than 

 the second and the fourth a little longer and more slender than the third. 

 Mesonotum dark reddish brown. Scutellum fuscous yellowish. Postscutellum 

 darker. Abdomen rather thickly haired, dark brown, genitalia yellowish. Halteres 

 whitish transparent basally, slightly fuscous apically. Coxae fuscous yellowish. 

 Legs mostly dark brown. Genitalia: basal clasp segment rather long, mod- 

 erately broad and with a roundly quadrate and thickly setose subapical lobe ; 

 terminal clasp segment rather short, stout; dorsal plate short, broad, broadly
