TWO NEW GENEBA OF LECANIINE COCCIDJE. 

 By T. D. A. Cockerell, N. M. Agr. Exp. Sta. 



Platinglisia, n. g. 

 $ . Scale differs from Inglisia in being quite flat, circular ; with 

 the glassy covering in two parts, divided longitudinally in the middle 

 line ; antennas and legs absent. Type, P. noacki. 



Platinglisia noacki, n. sp. 



$ . Flat, circular, 6£ mm. diam., reddish brown, with the mar- 

 ginal areas pallid ; glassy covering transparent, with the two halves 

 each having weak but easily visible concentric and radiating striaa, 

 surrounding and arising from a centre a little to one side of the middle 

 line of the insect. Under a microscope the glassy covering shows lines 

 of air-cells as in Inglisia, and irregularly placed larger air-cells in the 

 submarginal area. The insect has a deep longitudinal dorsal groove, 

 thickly beset with small gland pores, and ending at the anal plates. 

 This coincides with the suture between the glassy plates. The very 

 small mouth-parts, with very short rostral filaments, are to one side of 

 this groove, about the middle of the insect. The skin after boiling 

 remains yellowish brown, except a sharply differentiated colourless 

 marginal area ; the brown area presents groups of irregularly formed 

 gland-pits, the marginal area rather large round gland-pits. Extreme 

 margin dark brown, with few short simple spines. There is a little 

 white secretion in the spiracular regions, which remains as lines on 

 the leaf when the scale is removed. 



Hab. Campinas, Brazil, on the upper side of leaves of a 

 myrtaceous tree or shrub (Dr. F. Noack, No. 83). This is a 

 most remarkable Coccid, closely allied to Inglisia, but quite 

 worthy of generic distinction. 



Carpochlokoides, n. g. 

 2 . Globose, without legs or antennae. Larva of the Eriococcine 

 type, with numerous spines, and a comparatively short terminal seg- 

 ment to the antennae. $ sac white, composed of cotton-like threads. 



Carpochloroides viridis, n. sp. 



? . Adult. A globular sac, becoming transparent, but still more 

 or less greenish, after boiling ; no segmentation visible ; mouth-parts 

 well developed and large, the rostral sheath very dark brown, ribbon- 

 like ; skin without spines, except a very few minute simple ones at the 

 sides ; legs and antennae wanting ; anal ring not observed, it must be 

 very small. 



Larva, just hatched. Fusiform, not very elongate ; each segment 

 bearing numerous long spines arranged in a transverse row, which is 

 interrupted dor sally, and again subdor sally, four spines being on each 

 side between the dorsal and subdorsal gaps ; antennae 6-segmented ; 

 3 and 6 about equal, and longest, 1 and 2 next longest, then 4 and 5
