178 Journal New York Entomological Society, [Voi. v, blackish vittse on the thorax, all sub-equally separated from each other, the median pair being linear and more abbreviated behind than the others, which are more interrupted at the suture and curved inward be-hind. The hypopygium of the $ 's is more or less reddish. The brassy pollen of thorax extends downward over the whole pleurse, and on the underside of the front femora, in both sexes. The front tarsi of 9 do not seem to be dilated. The scutellum bears three strong posteriorly appressed marginal bristles on each side, of which the middle one is the shortest ; a short and weaker also appressed strongly decus-sate X-like pair in the middle on margin; and a shorter but sub-erect and straight pair immediately in front of the decussate ones. In the other points given by Williston (Trans. Am. Ent. Soc, 1888, p. 300), the specimens agree. LOCALITY AND FOOD PLANT CATALOGUE OF MEXICAN COCCID/E. By C. H. Tyler Townsend. 'J'he following is a complete list, with full localities, distribution, and food plants, of all the scale insects so far identified from Mexico. The number, which in 1893 "^^^^ ^^^ ^^j ^""O^^' reaches 80, including vari-eties, and four species found at Brownsville, Texas, which must surely occur near Matamoros. The new species mentioned, have been de-scribed by Professor Cockerell in the Canadian Entomologist, Vol. XXIX, p. 265, who has recently worked up the last lot of material col-lected for the Department of Agriculture. That portion of the material collected between April 24 and May 10, 1896, in Yucatan, Campeche and Laguna, was secured while on a trip for the Department. The determinations of all the species of my own collecting have been made by Mr. Pergande and Professor Cockerell. Mr. Pergand? determined most of the well-known species, while Professor Cockerell worked up new and less known forms. Llaveia axinus Lhve. (a) Halfway between Salina Cruz and Te-huantepec (Oaxaca). On unknown prickly bush, May 29, 1896. Coll. Towns. (<^) Tlacotalpam (Vera Cruz). On Jatropha sp., and Spoii-dias sp. Coll. by Llave. Peculiar to Mexico. " I believe the genus Llaveia will prove to be identical with Ortonia, from Ecuador and Guatemala " (Ckll.).
