80 HEMIPTERA-HOMOPTERA. 
5. Aulacaspis cattleya, Ckll., sp. n. 
2. Scales white, with the exuvie pale and marginal or nearly so. Living female insect plump, white (the 
juices immediately turn bright yellow in caustic soda). Median lobes &c. as in A. borsduvali, not as in 
A, bromelie. Circumgenital glands: median 8, anterior laterals 11-20, posterior laterals 11-15. 
Hab. Mexico, on leaves of Cattleya; found by Mr. A. Craw, 1899, in the course of 
his horticultural quarantine work at San Francisco. 
This is possibly a variety of A. boisduvali, but it seems to be a distinct species. It is 
what has passed as A. cymbidii (Bouché), and is figured by McIntire, Journ. Quekett 
Micr. Club, ser. 2, iii. pl. xxvi. The real A. cymbidii of Bouché was said to be from 
- China, and had a yellow female, and the scale “eiformig, flach, mit excentrischen 
Absatzen, an der zugespitzten Basis braun.” It could hardly have been our insect; 
possibly it was a Chionaspis.
