less finds good grounds for retaining Hlibner's term. The figure of tlie 

 cocoon wliich we have had prepared to iUustrate this article represents 

 a somewhat abnormal form. As a rule the cocoon is more or less hid- 

 den within the folds of the leaf. The insect is a southwestern form, 

 and its sudden occurrence near St. Louis would indicate that it is 

 spreading northward. — c. v. R. 



Loxostege maclurce n. sp. — Average expanse, 23"^™. General color above, lustrous, 

 pale-gray, argillaceous, with a more or less decided olivaceous tint, according to the 

 specimen, the legs, venter, hair on thorax beneath, basal joint of palpi, borders of 

 occipital tuft, and sometimes the basal joint of antennae and base of tongue above, 

 white. Eyes large, naked, varying from olive-green to dark-brown ; occiput, narrow 

 between the eyes, with a dense and evenly shorn tuft approaching in form a paral- 

 lelogram; palpi, densely clothed, the terminal joint porrect; tongue, with the basal 

 portion, clothed. Primaries with the dusky tran verse lines as follows: Basal line 

 across basal one-fourth of wing beginning at the sub-costal vein, angulate basally to 

 the median vein, then posteriorly to vein 1, and then almost straight across the wing 

 to the inner border. Median line across the middle of the wing, also beginning, in 

 a more or less distinct spot, at the sub-costal vein, and running irregularly with two 

 more decided curves outward between the bases of vein 4 and vein 2, and with two 

 curves inward from about vein 1 to the inner border. The posterior stripe starts at 

 the costa, where it is most distinct, about the posterior fourth of the wing, and runs 

 in a series of scallops nearly directly across the wing to vein 4, and then joins the 

 median line about its middle. Costa somewhat darker than the general surface, the 

 coloring intensifying to the falcate apex, which is more or less intensely black. 

 Fringes whice, with a black coincident inner border. Secondaries scarcely paler 

 than the primaries, and with a faint lunulate dark line across outer third; this line 

 obsolete in some specimens; fringes white or but very slightly darker, with coinci- 

 dent inner shade. Under surface more silvery than the upper surface, the primaries 

 having but a faint discal spot and lunule and the merest trace of the posterior dark 

 line ; the costa and the terminal space are, however, generally paler than the rest of 

 the wing : Secondaries with transverse line more distinct than on upper surface. De- 

 scribed from 10 specimens, reared from Texas and Missouri. 



There is considerable variation in the dusky lines, which are (in two specimens) 

 very distinct and continuous (especially the posterior one), but ordinarily they are 

 more intense on the veins and subobsolete bet ween them. In the $ the undersurfaces 

 are more distinctly silvery than in the female, while in this last the dusky line on 

 secondaries is most distinctly shown. The fringes sometimes show a double coinci- 

 dent dark shade and sometimes a distinct paler coincident inner line. 



THE FOOD PLANTS OF SOME JAMAICAN COCCID^. 



By T. D. A. COCKERELL, Kingston, Jamaica. 



During the last few months I have been systematically examining 

 various cultivated plants in order to ascertain what species of Coccidse, 

 if any, infested them. The result shows that in Kingston many species, 

 esi^ecially trees and shrubs, suffer from the attacks of scale-insects, 

 and also that the same scales not unfrequently occur on many different 

 hosts. It is not supposed, of course, that the food plants here given 

 are always or often the natural hosts of the various Ooccidae now found
