AMERICAN HOMOrTERA. 385 



mous, (^Pract. Ent. i, 90), which teaching is manifestly erroneous It 

 requires but a luonieuts observation to see that the Aapidiotua pini/ob'se 

 is of the same family as the "apple bark louse," and that it therefore 

 belongs to Lepidosaphidx (^Trans. Am. Ent. Soc. i, p. 373, Jan. 1868). 



The " White Pine louse" is extensively preyed upon by natural ene- 

 mies, among which I have observed the following : 



1st. — An interesting heteropterous insect that, in the larval state, 

 much resembles a brown ant, and runs about on the tree with a like 

 activity. This insect Mr. Uhler has kindly determined to be Cama- 

 ronotus frateriiua, Uhler. 



2nd. — The larva of an apparently undescribed Chri/psoj)a which 

 covers its back with the wooly down of the plant louse. 



ord. — The black lady-beetle — Chilocorus hivulneriis, Muls, abun- 

 dant. 



4:th. — Scjjmnns tcrmlndtia^, Say; and a somewhat similar but smaller 

 lady-beetle Pcntilla mi.^cUa. Zimm. MS. as determined by Dr. LeConte. 

 This beautiful little insect is one of the smallest of the lady-beetles, is 

 entirely black, the antennae are hairy, the club quite close, much more 

 so than that of Scj/mnwf tcrmlnatuif. the first joint thick, 2 — 8 slender, 

 6 — 8 very short, 9 and 10 catnpanulate, 11 truncate, conical; legs hairy. 



btli. — The larva of a species of ,Scijmnu<, longer than that of *S^. ter- 

 inatus, and from which I bred a beautiful Chalcis fly. * 



Qfh — Many larvas of unknown species of Sjrphidse. 



'•■Eutelus'? scymnse, n. sp. — % Thorax large, abdomen short, body brown, 

 covered with short hairs; head moderate, a broad, light yellowish band placed 

 vertically on median line of the face; ocelli none ; eyes large, elongate, reticu- 

 lated with whitish depressed lines ; legs lighter brown, naked, tarsi whitish, 

 spurs of middle tibire more than half the length of the tarsi ; middle legs long 

 and slender ; hind femora stout and curved inwardly, antennae long, slightly 

 downy, dark brown, except the terminal half of flagellum, which is white, tip 

 acuminate; wings grey-translucent, a dark spot at base, and a broad blackish 

 band across the middle, fading into lighter posteriorly, tips slightly fuliginous. 

 Length .07 inch
