324 THE CANADIAN ENTOMOLOGIST 



Upon 5. cnpressi Ehrh. and S. disticlium (Kuwana), appear to 

 belong to an unnamed group that includes Kitwanina parvus 

 (Maskell) also. I consider this group to be equivalent in value to 

 the groups at present recognized as tribes of the subfamily Dac- 

 tylopiinae. Whatever that value may be is certainly questionable 

 for this subfamily, Hke the genus Sphcerococcus , is a most unnatural 

 and but little understood group that riiust eventually be disrupted 

 and reorganized. Pending this upheaval I shall not name the group 

 under consideration, but shall merely indicate as many of its 

 characters as appear to be of value. The group may be character- 

 ized as follows: 



Coccidae referable to the subfamily Dactylopiinae (of the 

 Fernald Catalogue), that is: without abdominal spiracles; end of 

 the abdomen neither cleft nor pygidiform; without a pair of con- 

 spicuous lateral prominences. Distinguishable from the other 

 groups of the subfamily chiefly by negative characters. Without 

 dorsal ostioles or cerarii; anal lobes obsolete; without 8-shaped 

 pores; tubular ducts without a filamentous prolongation but bear- 

 ing at their inner extremity a more or less definitely multilocular 

 pore; anal ring nearly or quite simple, with from two to six very 

 small setae; antennae either well developed or vestigial; legs either 

 entirely lacking or well developed. 



Included genera: Kuwanina Ckll.; Ehrhornia . new genus; 

 Paludicoccus new genus. 



Key to Included Genera. 



1. Adult female with well developed legs and antennae, the latter 



6-segmented Ehrhornia, n. gen. 



Adult female without legs and with vestigial antennae, the latter 

 not more than 3-segmented 2. 



2. Adult female with a pair of small, circular cribriform plates 



on the ventral side of the abdomen Kuwanina Ckll. 



Adult female without cribriform plates Paludicoccus, n. gen. 



Kuwanina Ckll. 

 1903. Cockerell, T. D. A., in Fernald, Cat. Coccida^, p. 101- 

 Coccidae of the type described above. Adult female apodous 

 and with the antennae reduced to mere unsegmented tubercles.
