NORTH AMERICAN PHOROCERA ALDRICH AND WEBBER, 39 



and has been examined by the junior author; it is the same form as the 

 type of hoarmiae, which is in the National Museum (type No. 3591). 

 The specimen referred to in literature as Exorista hypenae Coquil- 

 lett but never described, is in the collection, and also belongs to the 

 typical form of blo7ida. Over 100 specimens reared from Cacoeeia 

 cerasivorona Fitch and fervidana Clemens at the gyv^y moth labora- 

 tory agree in having four dorsocentrals and the apical scutellars 

 turned'iip • this agreement would suggest a subspecific form, but other 

 specimens have one or both of the characters so that it is impossible 

 to define a group of any rank. In the series referred to, three-fourths 

 of the specimens have two sternopleurals and a vestigal third, but 

 the last-named one is absent on one side only in the other fourth. 

 Fifteen specimens bred from Cingilia catenana Drury at the gypsy 

 moth laboratory show the following differences in chaetotaxy : 

 Six specimens have three dorsocentrals, two sternopleurals, apical 



scutellars turned back. i . , • i 



Two specimens have three dorsocentrals, two sternopleurals, apical 



scutellars turned up. , , . i i.

One specimen with three dorsocentrals on one side, foui on the 



other, three sternopleurals, apical scutellars turned up. 



The species seems hardly less abundant southward than in ^e^^ 



England. Specimens in the collection are from New Jersey, New

Florida, Cuba, and Peru. i „.n .,11 from
