WEST INDIAN HOMOPTERA. 55 



(7.) Lecanium depreSSUm i'arg. — Mr. Barber has sent a scale 

 from Antigua which I think may be referred to this species, though 

 it is possibly distinct. He found it on garden Hibiscus, the double 

 and single red varieties, and remarks that it is enormously fertile. 



Female scale — long. 4, lat. 2, alt. H mm. Dark chocolate-brown, 

 elongate, convex, very shiny, somewhat obscurely transversely ridged, 

 margin granulose, not crenulate. An old scale is pale brown, very 

 finely reticulate all over with red-brown. The young are brown, 

 dorsally keeled, and strongly transversely ridged. 



A young specimen examined had unbi-anched hairs around the 

 margin, and very long spines at the lateral incisions. Color after 

 boiling in soda, transparent, with central parts, legs, etc., red-brown. 

 Eyes twice as far from base of antennae as from margin ; caudal 

 filaments nearly straight, slightly curved outwards. 



(S.). L. oleaB Bern. — Very common in Kingston, Jamaica, on 

 various trees and shrubs ; also sent from Antigua by Mr. Barber. 

 It varies in color from black to brown; on March 8, ]8'J2, Dr. 

 Strachan sent me a branch of Ficus carica, gathered in Kingston, 

 covered with L. olece, all of them brown. Perhaps the name testudo 

 Curtis, which cannot well represent a distinct species, may be used 

 for this brown form. 



(9.) L. hemisphoericum Targ. — Very common and destructive in 

 Kingston, Jamaica, especially on creepers. Mr. A. Fowler brought 

 me a fruit of Anonamnrlcata almost entirely covered by this species, 

 and presenting a most singular appearance. It also occurs at Cin- 

 chona, 5000 feet altitude, on Deiidrophthora cupressoides {W . Fa wcett;; 

 at Port Antonio, on Chrysanthemum (A. J. Hop wood) ; and else- 

 where. In Antigua, Mr. Barber finds it a "terrible pest to varie- 

 gated Eranthemum,'" and sends also a pale variety of it, which he 

 found on Salvia. I noticed that very young scales from Antigua, 

 on Erantkemum, were pale with three conspicuous transverse pinkish 

 bands. 



Mr. Caracciolo records this scale from Trinidad, where it is found 

 on gnava. 



(10.) L. filicum Bold.— On various ferns at Manchester Cottage, 

 Kingston, Jamaica. 



Adult scale brown, like hemisphoericum, but immatui'e specimens 

 longer and white. Margin of scale with clubbed hairs. The edge 

 of the scale orange-brown by transmitted light, appears crowded 

 with black dots ; these seem to extend more or less all over the scale.
