XII, D,i Robinson: Coccidse of the Philippine Islands 21 



This is very similar to P. dilatata Green ; it may be separable 

 on account of the difference in shape of male and female scales ; 

 the median lobes of P. inday (Banks) are longer and more 

 divergent. It is probable that this species should be considered 

 as belonging to Phenacaspis rather than to Chionaspis.

 Baiios {Baker) , on Mangifera indica. 



Phenacaspis eugenise (Maskell). 



Phenacaspis eugenise (Maskell) Fernald, Cat. Coccidae of the World 

 (1903), 238; Cockerell, Proc. Davenport Acad. Sci. (1905), 10, 134. 



Female scale elongate-oval, about 0.75 millimeter in diameter, 

 white. Caudal margin of adult female with divergent median 

 lobes, edges serrate; a spinelike plate laterad of these lobes, 

 two other lobes represented by broad prominences, each bear- 

 ing a spine. Circumgenital glands with median group of 6 

 to 8 orifices, anterior laterals of 16 to 18, posterior laterals of 

 18 to 20.

This species has not been definitely recorded from the Philip- 

 pine Islands. Cockerell remarks that a specimen collected by 

 Townsend "seems to be P. eugenise." 



Phenacaspis mischocarpi Cockerell and Robinson. 



Phenacaspis mischocarpi COCKERELL and ROBINSON, Bull. Am. Mus. 

 Nat. Hist. (1914), 33, 328. 



Female scale circular, about 1.75 millimeters in diameter, 

 dull white, exuviae lateral, pale orange, projecting beyond the 

 margin of the scale (Plate III, fig. 14). Female elongated, 

 broadened anteriorly, conspicuously segmented; caudal margin 

 with median lobes strongly divergent, serrulate on inner margins ; 

 second and third lobes each of two separate rounded lobules; 

 a spinelike plate and triangular projection laterad of median 

 and second lobes, a heavy spinelike plate laterad of third lobes, 

 three others on the margin beyond; margin beyond the lobes 

 irregularly dentate and with four incisions having thickened 

 edges (Plate III, fig. 13). Circumgenital glands with median 

 group of 8 or 9 orifices, lateral groups each of 16 or 17 orifices, 

 the anterior and posterior groups contiguous, almost confluent. 



Male scale about 1 millimeter long, tricarinate, exuvia pale 

 yellow.

 cescens.
