to the middle broadly suleate, while in C. monticola the same part is scarcely

Myzia Muls. 
This genus differs from Coccinella by its long and slenien antenne; I have 
included in it also Mulsant’s genus ‘Anatis, as I can‘*find no difference worthy 
of note. The following is new: 
1. M. Rathvoni, late ovata, utrinque fokbiaes angustata, thorace lateribus 
rectis, maculis duabus baseos lateribusque late albis, his puncto nigro notatis, 
elytris piceo-rufis, lateribus usque ad medium explanatis. Long. °4. 
I take great pleasure in dedicating this fine species to Mr. S. 8. Rathvon, of 
Lancaster, Pa., to whom science is indebted for many valuable additions to our 
entomological fauna. It was found at Sacramento, California, by Mr. Childs. 
Broadly oval, very convex, strongly narrowed before and behind, so as to be al- 
most angulated at the middle, on the sides. Head black, with an “obscure rufous 
spot each side. Thorax twice as wide as long, strongly narrowed in front, 
sides nearly straight, broadly margined; black, with two basal spots and a very 
broad lateral margin white ; the sides have a marginal black spot near the pos- 
terior angles. Elytra piceo-rufous, with some very indistinct black dots, of 
which the posterior series consisting as in M. 15-punctata of 6 spots is most 
distinct; the lateral margin from the base to the point of greatest breadth is 
strongly flattened and concave, and is blackish towards the middle. Beneath 
lack 
This is evidently a very dark colored specimen, and it is probable that on 
further exploration varieties will be found similar to the light colored and ocel- 
late specimens of M. 15-punctata.

One specimen, Vermont. Prof..C. B. Adams. Oblong elongate, convex, 
bright yellow, covered with fine short white hair. Head black, finely and not 
densely punctured, clypeus, mouth and antenne yellow. ‘Thorax finely punc- 
tured, rounded on the sides, base rounded, posterior angles subobtuse, not 
rounded. Elytra tolerably coarsely punctured, base and sides as far as the 
middle black; black portion broader at the scutellum and at the middle of the side ; 
dise with a common rounded black spot at the second third; beneath yellow; 
breast entirely black; prosternum black posteriorly. 
The anterior coxe in this genus are much smaller than in any other of the 
present tribe, and are almost round.

Guex, to whom I owe my specimens of this and many other interesting species. 
Size and form of E. marginipennis (Muls.) (E. pretertatus Mels. Pr. Ac. 3,178: 
Cocc. marginipennis Lec. An. Lyc. 1, 173.) Head black in the female, yellow 
in the male. Thorax very obsoletely punctulate, black; sides broadly rufous 
in the male, rufous only at the anterior angles in the female; base very much 
rounded, somewhat angulated, not margined. Elytra very finely and obsoletely 
punctulate, rufous with a large black spot near the apex and a little nearer to 
the suture than the side. Beneath piceous; sides and feet yellow.
