June, T903.] COLEMAN : CoCCID.t OF THE CONll-ER.E. Oa 



lar, basal segment bearing a single long heavy spine ; body bearing several rows of 

 long slender liairs. Characters of abdominal margin as follows ( Plate V, Fig. 9) : there 

 are four pairs of lobes ; the median pair are well developed, of medium size, rounded, 

 with a slight lateral notch ; second pair not so long as the median, rounded, but with 

 outer corner truncate ; third pair inconspicuous, broad, triangular and with terminal 

 margin serrate ; fourth pair of the same general shape as the third pair but broader 

 and less conspicuous, terminal margin also serrate ; a single broad plate between 

 median lobes, with four or five points ; two rather broad plates, with deeply incised 

 margins, between median and second lobes ; three broad plates, with deeply incised 

 margins, between second and third lobes ; a broad plate with slightly serrated margin, 

 followed by two rather narrow plates with deeply incised margins, between third and 

 fourth lobes ; a large dorsal and ventral spine at the base of each lobe. There are 

 five groups of spiimerets ; the anterior group consisting of three to five, cephalo-laterals 

 of about eight, caudo-laterals of two to five. ( I have examined over a hundred speci- 

 mens from different localities and on different hosts, and find a considerable variation 

 in the number and grouping of the spinnerets, but the above arrangement seems to 

 obtain in the majority of cases ; however, where the anterior laterals consist of three 

 or less, the caudo-laterals correspond.) 



Scale pf Male. — Smaller, darker colored and with exuviix; nearer one end than 

 in the female. 



Ailiilt Male. — I have found the adult male in mounting dried specimens but they 

 were not good enough for description. 



Larva. — The newly born larvce are about .3 mm. in length and about .2 mm. 

 in width; suboval in shape, narrowing anteriorly; color bright yellow; eyes incon- 

 spicuous ; antennae very long, five-segmented, formula, 5, 2, i, 3, 4, segment five 

 much longer than all the others together, ringed and with several stout hairs ; legs 

 rather long and stout, femur stout, tibia less than half the length of the tarsus, claw 

 long and slender and slightly curved, digitules of tarsus and claw, long and slender; 

 on the last abdominal segment there is a median pair of lobes which are quite con- 

 spicuous ; between these lobes there are two large tubercles bearing terminal hairs ; 

 other U)bes, plates and hairs are not well defined.
