peculiar, both long, but the upper oue filiform, with no distinct knob, 

 the lower stout and longer, with a very distinct knob. 



The posterior cleft of the larva is widely squared for its hindmost 

 half; and from it spring two cylindrical tubercles ; not extending 

 beyond its mouth, bearing each a long straight hair — the usual cau- 

 dal filaments. Between these tubercles is a pair of hooked organs, 

 the hooks pointing away from the central line. This arrangement 

 in the larva is interesting, and deserves further study. 



SECOND SERIES. 



This series consists of convex elongated (or at least not hemi- 

 spherical) species, which have been classed together for convenience, 

 but do not appear to form a natural group. They are L. msimile 

 Newst., L. hegonice Dough, L. berberidis Schr., L. elongatum Sign., 

 L. fitchii Sign., L. genistce Sign., L.juglandis Bouch., L. mori Sign., 

 L. persicce Fab., L. picece Schr., L. pruinosum Coquill., L. sallei Sign., 

 and one or two others. L. persicce is very near to some species re- 

 ferred to the third series ; it is not confined to the peach, for although 

 I have it from Isleworth, England, on peach (Q,. Manville Fenn), 

 what seems to be the same thing is received from Meissen, Saxony 

 (C. F. Schaufuss), where it was found on Viik vinifera and Spircca. 



(5.) Lecanium begoniSB Dougl. — Mr. C. A. Barber sent me from 

 Antigua some leaves of Tenninalia catappM, on which were manv 

 specimens of a Lecanium. I was at first inclined to consider it a new 

 species, but it is so near to L. begonice (of which I have Demerara 

 specimens, sent by Mr. Newstead) that I now doubt whether it is 

 even a distinct variety. 



The scales are abundant on the leaves ; along the midrib on the 

 upper side, but below more numerous, and scattered ; twenty-two 

 out of thirty-five on the under side of one leaf show holes where 

 parasites have escaped. The parasite is a Chalcidid, with a large 

 and thick tibial spur; femur and tibia bi'own ; tarsus whitish; stig- 

 mal vein rather long, bifurcate at end ; post-marginal about as long 

 as stigraal. 



Female scale rather over one-eighth inch long, broad-oval seen 

 from above, moderately convex; ends flatter than sides, so that the 

 outline seen from the side is pyramidal, while seen from one end it is 

 rounded. Scale shiny, somewhat granulose, especially at sides, so 

 dark brown as to appear black when adult, though some are obvi-
