is sixteen-spotted, with three additional rows of dark spots 

 on the abdomen. The body is broad and flat, with a row of 

 three spines on each side of the abdomen, and is .40 of an 

 inch long. 



In Chilocorus the margin of the elytra is dilated, and the 

 lunate prothorax is rounded behind. C. bivulnerulus Mulsaut 

 (Fig. 513) is black, with two yellow spots. 



The genus /Scymnus is hemispherical, pubescent, with short, 

 abruptly clavate antennae. I have received from 

 Dr. H. Shinier the larva and adult of Scymnus cer- 

 vicalis Muls. which he found in the holes of insects 

 boring in the Prickly-ash. The body is subcylin- 

 drical, pale whitish, much longer and slenderer and 

 narrower than in Coccinella, Avith a small black round head ; the 

 less are Ions: and slender, more so than in Coccinella. The

rings are rather convex, not tuberculated above, 

 though provided with a few hairs. It is .12 of an inch 

 long. The beetle is reddish brown, with very dark 

 Fig. 5U. p rilss ian blue elytra, and is .10 of an inch long. 



Epilachna borealis Thunberg (Fig. 514) is yellowish, with 

 seven large black patches on each elytron. "The larvae, 

 according to Osten Sacken, are common on the leaves of the 

 pumpkin. It is yellow, with long, brown, branched spines, 

 arranged in rows of six on each segment, except the first tho- 

 racic segment, which has only four. The pupa instead of 

 spines has short bristles, especially on the thorax."
