MONOPHLEBIN A. 
MONOPHLEBUS, Leach. 
[Liaveia, Signoret. ] 
The supposed distinctions between Monophlebus (= Llaveia, Sign.) and Protortonia 
are due to the immaturity of the type-specimens of the latter group. Adults of 
Protortonia primitiva have 11-segmented antenne. See Proc. Acad. Nat. Sci. Phil. 
1899, p. 259.

This insect is coral-red ( 2 ) and is covered with a fine whitish powder. From the 
females is extracted 26 to 28 °/. of their weight of a bright yellow fat, which is said to 
be the most quickly drying oleaginous substance known.

* By T. D. A. Cockzrern, Nearly all of the material of this family has passed through my hands. -A 
detailed list of Mexican Coccide, with food-plants and localities, was published by Prof. ©. H. T. Townsend in 
Journ. N. Y. Ent. Soc., Dec. 1897. Since then, forty new species have been described from Mexico in Journ. 
N. Y. Ent. Soc., Sept. 1898, Ann. & Mag. of Nat. History, June 1898, and ‘ Entomologist,’ June 1898. Iam 
responsible for the identification of the Panama species collected by Mr. Dolby-Tyler. In working over the 
collection procured in 1898 by Prof. Townsend I have been assisted by Mr. P. J. Parrott, of the Kansas 
Agricultural College.—7. D A. C.
