Three of the above are new forms recently discovered by 

 Professor C. H. T. Townsend, as follows: 



(1.) Icerya Uttoralis var. tonilensis, n. var.— -Tonila, Jalisco, 

 Aug. 2, 1902. Externally like Uttoralis, but only 8 mm. long, 

 with ovisac, which curves upwards. 



Ovisac not over 3 mm. broad, strongly yellow at base. 



The larva has slender antennas, with a large stout club, 

 which is not constricted; the joints measured in /i. (1.) 30. (2 ) 

 36. (3.) 30. (4,) 27. (5.) 23. (6.) 90. 



The male (hatching about Sept. 1.) is blackish; hind part 

 of thorax, and abdomen, crimson. Abdomen ending in two 

 long hairy fleshy crimson processes, which are nearly as long 

 as abdomen. Wings grey, with costa broadly red, the red bor- 

 dered beneath by blackish; two white lines, between which is 

 a broad blackish stripe, only about half as long. The pattern 

 of the wings resembles that of Monophiebus raddoni, Westwood. 



(2.) Icerya colimensis, n. sp.— Manzanillo, Colima, July 18, 

 1902. (Townsend). Female with ovisac 10 mm. long. 4 broad,
