median pair on three or four abdominal segments and an occasional duct on the dor- 

 sum of the thorax they are confined to the lateral margins, there being normally six 

 or seven at each lateral margin of the penultimate segment and two or three at each 

 lateral margin of the other abdominal segments (except the last) and the thoracic 

 segments also, together with an indefinite number on the head. Dorsal body setae 

 relatively few, small and slender. Ventral setai much longer. Anal ring noticeably 

 large, rather weakly developed. Anal ring seta; about twice as long as the diameter 

 of the anal ring and slightly shorter than the anal lobe seta;. Antenna; and legs 

 rather slender, the antennae eight-segmented, the claw without a tooth. 



Material Examined. From various hosts in Hawaii, Philippine 

 Islands and Nicaragua and from the following hosts and localities 

 in Florida; mulberry and Magnolia at Gainesville; undetermined 

 weed at Winter Haven; Oleander at Key West. 



Notes. This is far from being a typical Pseudococcus. In the 

 nature of the ducts it resembles Phenacoccus stachyos Ehrh., but the 

 latter has nine-segmented antennae, eighteen pairs of cerarii and a 

 tooth on the claw.

Through the kindness of Mr. Ehrhorn I have been enabled to 

 examine the type slide of Pseudococcus quercus. The slide contains 

 two specimens, of which one is P. crawii (Coq.) and the other P. 

 quercicolus Ferris. This being the case the name quercus, which I 

 have previously placed as a synonym of crawii may be revived for 

 P. quercicolus. 



Lachnodius phoradendri( Ckll.)

Publ., p. 23, f. 7. 



Through the kindness of Professor Cockerell I have been enabled 

 to see a slide from the type material of Pseudococcus phoradendri Ckll. 

 There can be but little doubt that my Lachnodius salicis is the same.
