Professor Cockerell’s original notes on the material, I think it constitutes 
a good variety. 
4. Phenaooccus n. sp. — Found by Mr. E. A. Schwarz on twigs of 
Mozinna spatulata Orteg., June 7. This scale much resembles a mono- 
phloebid; it is wax-red, with a brown stripe down each side of the body. 
The material was largely parasitized, and more is needed for description. 
5. Daciylopius virgatus Ckll. — On Cereus princeps Ilort. Wiirzb., June 
1, in large numbers. Eggs, young in all stages, and adult females. June 
10, very numerous on guava; and June 6 to 17, on Abutilon holosericeum 
Scheele. The males, apparently this species, were found on guava, 
May 28. 
6 . Daciylopius sp. — On Cordia boissieri A. DC., a tree known as ana- 
cahuita. Adults on branches, and young on leaves; also on buds and 
young fruit, June 6. It may he mentioned here that specimens of 
Daciylopius were taken June 1, on Pithecolobium flexicaule Coult. 
(ebony); June 5, on Mozinna spaiulata Orteg.; June 6 , on Croton capi- 
tatus Michx.; and June 25, on Clematis drummondii T. & C. It is not 
possible to determine them, on account of scanty material in each case. 
7. Ortlnezia sp. — Males flying in the palmetto hammock at San Tomas, 
June 7. Of a beautiful pale azure color, with many long white anal fila- 
ments in a wisp-like bunch. Could find no females on any of the plants 
in the neighborhood. 
8. Pulvinaria simulans Ckll. var. — In large numbers on underside of 
leaves and stems of a cultivated bush, probably belonging to the Capri- 
foliaceae, June 1. Also on Cereus princeps, in less numbers. The ele- 
gant yellow ant, Pseudomyrma pallida Sm., was found attending these 
scales. 
9. Lecanium hesperidum Linn. — On orange, in Matamoros, June 1 . 
In great numbers on oleander, at Point Isabel, June 8. On orange, at 
Corpus Christi, December 5, 1894. 
10. Lecanium oleae Bern. — On fig, February 11. On Prythrina Jier- 
bacea, February 20. On fig and oleander, in Corpus Christi, December 
4, 1894. 
11. Lecanium imbricatum Ckll.— Found a number of specimens on 
bark at base of live cotton stalks, at San Tomas, April 5. This species 
was discovered by me at Alta Mira (near Tampico), Tamaulipas, October 
15, 1894. 
12. Lecanium sp. — June 23, on leaf of Clematis drummondii T. & G. 
13. Aspidiotus rapax Comst. — In great numbers, on oleander at Point 
Isabel, June 8. 
14. Aspidiotus nerii Bouche. — On oleander, February 3. On china 
tree, Mclia azedarac, in Matamoros, June 6 . 
15. Aspidiotus ficus Ash in,- — Yery abundant on orange at San Tomas,
