52 Mr. T. D. A. Cockerell on some Mexican Coccidas. 



I do not know any species nearly allied to this. It is 

 easily distinguished by its bright yellow ovisac, bristly margin 

 of the female, long femoral bristle, and the large thick digi- 

 tules of the claw. It is possible that the two bristles ascribed 

 to the trochanter are really on the distal end of the coxa. 



(8) Lecanium olece (Bern.). 

 City of Mexico. 



(9) Lecanium hesperidum (L.). 



On stems of rose, Vera Cruz; on tree (not identified), City 

 of Mexico. 



(10) Lecanium terminalicSj Ckll., var. 



On leaves of a liliaceous plant, Vera Cruz. 

 ? (adult). Margin with very few (simple) hairs. Derm 

 with small circular gland-spots. Sides of scale with radiating 

 pigment-bands. Parts of the scale and insect turn reddish 

 purple in soda. Anal plates with their posterior external 

 margins considerably longer than their anterior margins. 

 Legs small ; tarsus with slender knobbed hairs, knobs rudi- 

 mentary ; tarsus about two thirds length of tibia ; tibia about 

 three fourths length of femur. 

 Eggs oval, granular. 



Larva with long and slender knobbed tarsal hairs, the knobs 

 rudimentary. Femur decidedly shorter than tibia + tarsus. 



L. terminaUce was described from specimens found on 

 Terminah'a at Jamaica, and its occurrence on a liliaceous 

 plant at Vera Cruz was quite unexpected, so much so that 

 until I examined the details of its structure I did not suppose 

 I had terminaltce, but rather Signoret's acuminatum, which 

 was found on orchids in a Parisian hothouse. 



These Vera-Cruz terminalice were only a few feet away 

 from a rose-bush swarming with hes^peridum, and as one looked 

 at them it was hard not to conclude tliat they were all one 

 species, the terminalia' modified by the nature of the food- 

 plant. Yet in Kingston, Jamaica, where one finds terminalice 

 on Terminalia, I have found occasionally on liliaceous plants 

 true hesperidum, and not terminalice at all ! 



In some few respects, such as the details of the feet, the 

 Vera Cruz specimens differ from typical terminalice ; but I am 

 certainly not prepared to make a new species out of them on 

 these grounds. From acuminatum they differ in the length
