are also some on the disc ; at the extremity of the tenth joint there are 

 two long hairs and a number of short ones : feet blackish, rather long. 



Reported from Ceylon. 



Llaveia, Sign., created for a Mexican species which approaches 

 PorpJiyroiohora in the form of the first pair of feet and Monophlehus in 

 the number of the antennae. [A. S. E. F. (5 ser.) v, p. 370, 1875]. 



Tessaroheliis, Montr., created for a species from New Caledonia in 

 1864, [An. Soc. Linn. Lyon, xi, p. 246, 1864, and Sign., A. S. E. F. 

 (5 ser.) vi, p. 600, 1876]. 



Dr. J. Anderson, in his * Letters to Banks ' (1786 — 89), quoted by 

 Signoret, has noticed and named several species of CoccidcB from the 

 Madras Presidency, but his descriptions are so meagre and imperfect 

 that but little use has been made of them. Amongst those mentioned 

 by him are the following : — 



1. Coccus cMcBoon, found on the Air a indica, and which Signoret 

 would refer to Dactylopius [A. S. E. F. (5 ser.) vi, 612, 1876]. 



2. G. oogeneSi found on the Phyllanthus emblica, Euphorbia hirta, 

 Tinospora cordifolia, and Hibiscus populneus in Madras. Anderson de- 

 scribes this species as purple-red and surrounded by a silky material 

 of which the threads are as fine as those of a spider's web and can be 

 drawn out to several inches before they break : the adult ? deposits 

 her eggs in a silken receptacle and had no rostrum : the S is of an 

 amber colour [Sign., 1. c. 621]. 



3. G. trichodes, found on the guava, Anona squamosa, Solanum 

 lycopersicum, and Hibiscus rosa-sinensis : Signoret would refer it to 

 Dactylopius. The ? is inclosed in silken threads which fall ofE when 

 she deposits her eggs and serve to hold the young on the food-plant : cT 

 of an amber colour with two opaque white filaments which are longer 

 than the body ; wings uncoloured and transparent, but after a few days 

 slightly crimson : antennae 10-jointed and on each joint a few hairs : 

 segments of abdomen visible ; limbs pubescent [Sign., 1. c. 625]. 



4. G. erion, found on the orange, Bobinia mitis, Hibiscus rosa- 

 sinensis, Ficus indica, Erythrina corallodendron, Cocos nucifera, and 

 Myrtus zeylatiicus : Signoret assigns it to Dactylopius : of a purple 

 orange or a chocolate brown. [Sign., 1. c. 615.] 



5. G. microogenes, found on Vitis vinifera and Galega prostrata. 

 Of a deep red, with a bright white silky covering, the red disappear- 

 ing in the advanced stage : ? with the margins rimmed and becoming 

 sometimes dull grey and sometimes scarlet : S with two wings which 

 when closed are twice as long as the abdomen and two long filaments 

 at the anal extremity. Signoret suggests that this may be the same as 

 Falvinaria vitis, [Sign., 1. c. 620].
