WEST INDIAN HOMOPTERA. 53 



ously brown. In outline, color and texture, these Antigua scales 

 exactly resemble the Demerara begonioe, but my specimens of the 

 latter are smaller, and have a rather more pronounced anal notch. 



The structure of the scale is noteworthy, consisting of distinct 

 oblong plates, each having in its centre a circular gland-spot. This 

 is only seen by transmitted light. 



On the Terminalia leaves from Antigua were also j)lenty of L. 

 olece Bern. 



(6.) LecanJUm aSSimile Newst., var. amarylUdis, n. var. — In 

 numbers on the leaves of Amaryllis, sp., in Antigua, sent by Mr. C. 

 A. Barber. Scale about 3 mm. long, or less ; black, with a pale 

 margin, or red-brown. The pale margin is finely striate-plicate ; the 

 black portion is shiny, examined by transmitted light it appears 

 brown. 



Derm with scattered gland-dots. Sides of posterior cleft contigu- 

 ous, the cleft short, not nearly twice as long (counting from tip of 

 anal plates to margin) as length of anal plates. Anal plates pale, 

 long wedge-shaped, the two posterior angles of the triangle much 

 greater than the anterior one. Margin with but few hairs, these 

 small, slender, with a slight tendency to be knobbed ; marginal 

 spines single, each in a deep squared incision, beyond the mouth of 

 which it does not project. 



Tibia about one-fourth longer than tarsus ; femur about one-fourth 

 longer than tibia ; distal end of tibia with two hairs, one short, the 

 other rather long. 



Antennae with apparently eight joints ; third joint longest, but 

 foui'th almost as long, second next longest; then fifth, sixth and 

 eighth subequal ; then first ; then seventh. It is difficult to make 

 out the joints, as some of them show constrictions, or *' false joints,' ' 

 but I think the statement here given is correct. There is a hair on 

 first joint, one at end of fourth, one at end of fifth, and at end of 

 sixth, and several on the eighth. 



This is very likely a distinct species, but nearly all of Mr. New- 

 stead's short description of amiin'de will apply to it. L. assimile, 

 has 7-jointed antennee, and the hairs on them seem to be disposed 

 differently. The slight difference in the stated proportions of tibia 

 and tarsus, and in the size of the scales, cannot count for much. 



Several sj)ecimens of amaryllidia show lioles where i)arasites have 

 escaped.
