and each ring of the body produced into a remarkably long, 

 soft, flesh}^ tubercle, while there are two rows of black spots 

 along the back. 



In the genus PJiengodes, the females of which are not yet 

 known in this country, the third and following joints of the 

 antennte emit two very long, slender and flexible pubescent 

 branches from near the base ; the second and third joints are 

 A^ery short. The elytra are one-third the length of the abdo- 

 men, and are strongly divergent and subulate. Dr. Leconte 

 describes Phengodes plumosa Oliv. as being testaceous, with the 

 antennae, excepting the base, and the narrow tips of the elytra 

 fuscous, and the sides of the thorax broadly depressed ; it oc- 

 curs from New York to Texas. In Chmdiognathus the antennae 

 are filiform ; the elytra are as long or nearly as long as the 

 abdomen and rounded at tip, while 

 the anterior margin of the thorax is 

 rounded. C. Pensylvanicus DeGeer jA

 the grubs of the plum curculio. (American Entomologist, i, 

 p. 35.) In Telephorus the head is never concealed by the tho- 

 rax, and the latter is rounded from the sides along the front 

 margin, the front of the head is emarginate at tip ; the claws 

 are toothed, being rarely cleft. The species are found on the 

 leaves of trees in June. Walsh states that the larva of T. 

 Carolina Fabr. preys on wood-feeding larvae. Mr. P. S. 

 Sprague has reared the larva of T. hiUneatus Say. He found 

 it near Boston under stones in spring, when it pupates, and 

 early in May becomes a beetle. It is found on the leaves of 

 the birch as soon as thc}^ are expanded. 



MALAcniD.E Redtenbacher. This small group, often united 

 with the preceding family, is chiefly distinguished by the an- 

 tennte being inserted on tlie sides of the front, and by the body 

 in some genera being furnished with soft extensible vesicles, 

 while the alxlominal segments are in part meml)ranous. 3f(da-
