555* Diplolepis fulgens (Gill.). X 1. 190. On Rosa blanda . Adults May 1-21 
and May 15-June 1 (Chi). Grodie reared the maker May 18-29 (Toronto). 
Similar adults were reared from galls on a cultivated Rosa rugosa on 
May 17 and June 8-12 (Chi). 
554. Diplolepis utahaneis ( na ss.). X 1. 204. On Rosa ap. Adults emerged 
May 12-June 1 (Chi). 
Diplolepis dichlocerus (Harris). 189. Fig.522. On a wild rose. Adults out 
May 22-June 21 (Chi). Some females were liberated on a small wild rose 
recently ^transplanted to a greenhouse and having fresh shoots 5-6 m« 
high. On May 25 a female was seen ovipositing near the top of one of 
these shoots. On June 5 a belt of glandular hairs at this point was 
the first evidence of gall formation and by June 18 the gall was 5 mm. 
in diameter. Adults emerged from this gall in the greenhouse the next 
spring before March 15. 
355. Diplolepis fusiformans (Ashm.). X 1. 191. On a wild rose. Adults emerged 
May 15-25; May 5^-June 17 (Chi). Brodie reared the maker from galls 
on Rosa blanda June 18-20 and June 24-July 7 (Toronto). 
Diplolepis nodulosa (Beut.). 197* Fig*525« On Rosa rubiginosa , sweetbrier. 
Adults emerged May 25 to early June (Chi). 
556. Diplolepis bicolor (Harris). X 1. 188. On Rosa blanda. In the Chicago area 
galls are full-grown but still succulent the last of June, turning 
brown in July, after which they may be gathered for rearing. Kept in 
greenhouse adults emerged Apr.50, May 17, May 20. 
Diplolepis pustulatoides (Beut.). 198. On a wild rose. Adults out May 24. 
557* Diplolepis rosae (L.). X 1. 2ol. Mossy Rose Gall. On Rosa rubiginosa , the

558* Diplolepis multispinosa (Gill.). X 1. 195. On a wild rose. Adults emerged 
May 10-15; Apr.25-May 15 (Chi); May 5 (Wis.)j Apr.5-6 and May 20-50 
(Minn, on Rosa rugosa ). Brodie reared the maker from gall on Rosa 
blanda June 21; May 5-51; Apr.19-25 and May 19-June 2 (Toronto). 
559. Diplolepis nebulosa (Bass.). X 5. 196. On a wild rose. Determination is 
questioned for the description says galls are 5-6 mm. in dia. and 
close to midrib on the under side of the leaf. Galls of this sort 
on rose in summer need further study. 
Diplolepis mayri (Schlecht.). 194. A single female determined as this 
European species was reared in May from a rose of European origin in 
nursery in New Jersey. Others from galls on Rosa rubiginosa at Dayton, 
Ohio were reared May 12,15,15,18. 
540. Diplolepis gracilis (Ashm.). XI. 192. Oh a wild rose. Adults emerged 
the next spring May 15-June 10 (Chi).

Apr.15 (Chi); May 14-25 (Long Island, N.Y.). 
542. Diplolepis rosaefolii (Ckll.). X 5. 202. On a wild rose. Adults emerged
