Dec. 1899.1 CoCKERELL: RECORDS OF COCCID^. 257 



NEW RECORDS OF COCCID^. 



By T. D. a. Cockerell, 



The following records add considerably to the known range of a 

 number of species, while for others new food plants are indicated. 

 Through the agency of man, Coccidje are being spread far and wide, 

 and it is becoming an urgent necessity to investigate their natural and 

 artificial distribution more thoroughly than we have hitherto done. 



Eriococcus quercus {Comst.^. — Guanajuato, Mexico, on an unde- 

 termined tree or shrub. Coll. Dr. A. Duges. New to Mexico. The 

 fourth antennal segment is, in most of the Mexican examples, longer 

 than in those from Florida. 



Ceroplastodesniveus {Ck//.). — Agnas Calientes, Mexico, Jan. 5, 

 1891. Coll. Prof H. Osborn. Com. W. Newell. Known hitherto 

 only for the original types collected in 1893 at Montezuma. 



Lecanium imbricatum Ck/l. — Fillmore Canon, Organ Mts., New 

 Mexico. Coll. Ckll. on Acacia. New to New Mexico, and to the 

 Upper Sonoran Zone. 



Lecanium quercitronis Fitch. — N. Syn. Kermoides, Tyrrell. 

 Soledad Canon, Organ Mts., Aug. 12, 1897, on oak. Coll. J. D. 

 Tinsley. This extends its known range in the Rocky Mts. consider- 

 ably to the south. 



Lecanium armeniacum Craw. — Guanajuato, Mexico, on peach. 

 Coll. Dr. A. Duges and Dr. Jesus Aleman. The scales are just like 

 L. persica;; but the antenna, sometimes with 7, sometimes with 8 seg- 

 ments, do not agree in the proportions of the segments with those of 

 persicce. I had regarded the insect as a form of L. persiccK, but Mr. 

 Pergande protested that it must rather be artneniacuvi; and on further 

 consideration, I must agree with him. It is new to Mexico. 



Vinsonia stellifera ( Westw.'). — On an orchid from Central Amer- 

 ica, brought by rail to Los Angeles. Com. Alex. Craw, Jan., 1898. 

 New to Central America. 



Comstockiella sabalis (^Co>?ist.), var. — Guadalupe Island, off the 

 coast of Lower California, on fruits of the palm Erytliea edu/is S. Wats. 

 Div. Entom., U. S. Dep. Agric, no. 4933. Dried 9 ochreous, but 

 when boiled in KHO becoming purplish or even crimson. The largest
