ART. 12. MASKELL GENERA OF COCCLDAE MORRISON. 77 



Larva (embryonic).— Elongate oval, antennae G-segmented, legs 

 normal, claw with denticle, digitules slender, one tarsal longer and 

 larger than the other, inserted above it, one of the claw similarly 

 enlarged; mentum very short, 1-segmented; body margin with a 

 continuous closely set row of clavate spines, some slightly smaller 

 than others, accompanied above and below by more widely sepa- 

 rated tiny submarginal setae ; with a pair of long slender hairs ven- 

 trally anterior to the anal ring; body apparently without gland 

 pores ; anal plates slender, tapering, with a long apical seta and six 

 other slender setae ; anal ring small, with pores and six setae. 



Cotype.—Cixt. No. 24771, U.S.N.M. 



Eleven species besides the type have been included in this genus 

 by various writers. After an examination of specimens or descrip- 

 tions of all of these, the conclusion that no one of them is congeneric 

 with the type is unavoidable. The peculiar character of the margi- 

 nal spines and the complete lack of differentiation of the spiracular 

 spines in both adult and larva, and the development of the unusual 

 compound cribriform plates in the adult all serve to separate the 

 type species sharply and widely from the other species included in 

 the genus, and similarly from the other species and genera of the 

 group in which the genus has been placed, in so far as the latter are 

 known to the writers. 



The following generic diagnosis is therefore confined to the type 

 species. 



GENERIC DIAGNOSIS OF INGLISIA. 



Coccine forms (of Fernald Catalogue) covered, in the older stages 

 at least, by a glassy, vertically striated test or shell, conical in the 

 type; body of adult female delicate, convex above, short and the 

 margin angular, anal cleft very short, antennae indistinctly 7-seg- 

 mented, legs normal, mentum 1-segmented, marginal spines of two 

 sorts, tapering and slender, and stout clavate, alternating, spiracu- 

 lar spines not differentiated, dorsal and ventral setae present, mostly 

 very few and scattered, with only long tubular ducts and small 

 quinquelocular disk pores (ventral), anal plates small, triangular, 

 with several stout setae along inner margin of each, anal ring with 

 pores and six setae; larva elongate oval, antennae 6-segmented, legs 

 normal, body margin with continuous series of closely set clavate 

 spines, spiracular spines not differentiated, anal plates slender, ta- 

 pering, with long apical seta and several others, anal ring with 

 pores and six setae. 



Some of the structural characters of this genus suggest a relation- 

 ship to the subfamily Asterolecaninae, notably the dorsal cribriform 

 plates, the peculiarly shaped anal plates, and the glassy external 

 covering, but other characters do not bear out this suggested rela-
