insect. Fleischer ia paulensis v. Hohnel, on twigs of a Melasto- 

 macess, Sao Paulo. Cantareira, type ex Herb. v. Hohnel, is quite 

 indistinguishable fi'om H. amhiens. Specimens from Venezuela 

 ex Herb. Thaxter (Coll. A. F. Blakeslee) are bright brownish- 

 red ; they are tuberculate towards the base. 



Pycnidia have not been found in any of the specimens cited 

 above. In a collection from Trinidad {ex Herb. Thaxter) some 

 of the examples contain both pycnidia and perithecia, the former 

 near the margin, and the latter in the centre ; the pycnidia are 

 globose, 0"2 mm. diameter, and the pycnospores are fusoid, 

 9-13 X 1-1 * 5 [JL. The specimens are circular, scutate, or flattened 

 pulvinate, up to 4 mm. diameter, and 1 mm. thick in the centre ; 

 most of them thin out to a margin about • 1 mm. thick, but some 

 ar3 • 7 mm. thick at the edge ; the coloiu" is now black, but 

 sections show a yellow-brown deposit beneath the black exterior. 

 These are on a large flat Lecanium, and their shape is striivingly 

 similar to that of H. ollvacea under the same conditions. In Herb. 

 Kew, sub Aschersonia oxijspora, there is a leaf bearing Aschersonia 

 turhinata, collected by Spruce at San Carlos and recorded by 

 Berkeley under the former na.me in Hooker's Journal of Botanj^ 

 and Kew Garden Miscellany, VIII. (1865), p. 278. Among these 

 is a specimen which appears to be the Aschersonia stage of H. 

 ■palmse. It is black, semiglobose, slightly contracted at the base ; 

 it is situated excentrically on the scale and consequently the base 

 is expanded on one side ; the surface is minutely roughened ; 

 internally it is now purplish -fuscous ; the pycnospores are fusoid, 

 ends not tajiering, 8-10 X 2 \x.

 greenish-yellow, then olive-brown, or dark rufous brown, 

 finally blackening ; internally pale yellow or white, with a 

 brown zone at the periphery. Ostiola scattered, projecting.
