116 THE COCCIDAE 



of anacerores excreting a long glassy tube. The caudal abdominal seg- 

 ment is not short, narrow, and projecting. 



The male has eight ocellanae on each side of the head, forming an 

 almost complete circle, and two distinct ocelli. The abdomen is not pro- 

 vided with long lateral filaments, but the caudal end bears on each side 

 of the meson a bundle of four to six rather long setae and a very long 

 thick thread-like filament of wax. The wings are sometimes greatly 

 reduced. The stylus is inconspicuous. 



This subfamily contains a single genus, Phenacoleachia, based 

 upon a species described by Maskell from New Zealand. There is 

 but little known regarding the life-history of the species. Maskell 

 describes the adult female, the first nymphal stage, and the adult 

 male. The species resembles closely many species of Pseudococcus 

 in its general habits and general appearance. 



The adult female is eight millimeters or less in length, the 

 two ends of the body are rounded, and the caudal end lacks all 

 indication of anal lobes and anal setae. These structures are 

 characteristic of most species provided with a prominent anal ring 

 and anal ring setae but are not characteristic features of this one 

 The antennae are long and consist of eleven segments. The body 

 is covered with mealy and cottony wax, some of the latter form 

 long curling coarse yellowish threads. Some of the caudal 

 abdominal segments bear small porrect pencils of wax which give 

 the insect the general appearance of a mealy-bug. 



The nymphs are similar to the adults but smaller. They are 

 similarly covered with wax and bear about the same number, five 

 or six, pencils or lateral projections of wax. The antennae consist 

 of seven segments. The rostrum is elongate and, as in the adult, 

 consists of three segments. Those species provided with an anal 

 ring and lacking anal lobes in the adult, generally have large 

 prominent anal lobes in the nymphal stages, particularly the first, 

 but there are no indication of such structures in the nymphs of 

 this species. 



The adult males are about two millimeters long and rather 

 densely covered with white mealy wax. The eyes are represented 

 by eight ocellanae on each side and, except for a small space on 

 the meson of the dorsal and ventral aspects, form almost a complete 

 ring about the head. There is on each side of the meson of the 

 dorsal aspect caudad of the ocellanae two other simple eyes which 

 are considered as ocelli. The antennae consist of ten segments. 

 The legs are long and slender. The caudal end of the abdomen 

 bears two long, slender, thread-like filaments of wax. The wings, 

 while normally large and prominent and held in place by halteres
