pores ; lobes very thick, basal outline somewhat horn-shaped and at the angle formed 

 by the jimcture of the base and outer edge is a well defined tubercular projection. 

 Submarginal compound pores (fig. 4, e) very large and presenting an exceedingly 

 minute reticulated surface ; these are arranged as follows : one, the largest, about 

 midway between the base of the rostrum and the margin ; one in front of, and 

 another between each of the spiracles, making five in all ; these structures are 

 possibly analagous to the " cribriform plates," but have much finer gratings. Derm 

 of both dorsum and venter thickly set with minute ovate glands, each with a circular 

 opening having a well defined chitinous ring. 



Length, 3*8-5 mm. 



Larva with well developed legs and antennae. 



British Guiana: Georgetown, on Microlobium acaciaefolium, 28.xii.13 {G. E. 

 Bodkin). 



Mr. Bodkin also adds the following details : " This Coccid was discovered beneath 

 the bark of a tree growing in the Botanic Gardens. It was attended by a small black 

 ant which occurs commonly, especially under the bark of trees. The bark could 

 be easily removed with a knife. The Coccids were observed to occur in small colonies 

 of two to three or three to five together. They were apparently entirely hidden 

 from the light. The colour of the adult females, when alive, is dull pink. The 

 young larvae are bright pink in colour and extremely active. Ova are produced by 

 the female." {In litt. 3.i.l4). 



Lecanium hirsutum, sp. nov. 



Female, adult. Short ovate, rarely sub-circular ; integument thin ; colour in 

 alcohol dusky yellowish-white to ochraceous buff, margin usually distinctly darker. 

 Integument of the dorsum clothed with long spinose hairs and thickly studded with 

 glands (fig. 5, a), the central orifice of the latter surrounded by several somewhat 

 irregular lobate processes. Antennae (fig. 5, h) rather short and stout, of seven or 

 eight segments, usually eight, of which the third is the longest. Legs stout ; tarsus 

 (fig. 5, c) much shorter than the tibia ; claws short and very broad proximally ; 

 upper digitules long and rather stout, distal extremity distinctly dilated and flat- 

 tened ; lower digitules unusually broad and flat. Stigmatic cleft (fig. 5, d) well 

 defined and much wider proximally than distally ; spines short, seven to nine in 

 number, three or more being much stouter than the rest, but not all arranged in the 

 same plane. Marginal hairs numerous and similar to those on the dorsum, into 

 which they merge imperceptibly ; close up to the bases of many of these are two 

 distinct pores (fig. 5, a). In the young adult females the margin (fig. 5, /) is also 

 thickly set ivith short stout sjpines, but these organs are so easily deciduous in the old 

 adults that they are rarely present. Anal lobes (fig. 5, e) with the base as long as 

 the outer edge ; apex with an unusually long hair. Hairs of the anal ring extremely 

 short, being scarcely as long as the lobes. 



Length, 3-4 mm.
