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

 soft, fleshy tubercle, while there are two rows of black spots 

 along the back. 



In the genus Phengodes, the females of which are not j^el 

 known in this country, the thh'd and following joints of the 

 antennae emit two very long, slender and flexible pubescent 

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

 very short. The elytra are one-third the length of the abdo- 

 men, and are stronglj- divergent and subulate. Dr. Leconte 

 describes Phengodes plmnosa 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 Chanliognathus the antennas 

 are filiform ; the elytra are as long or nearl}' as long as the 

 abdomen and rounded at tip, while 

 the anteinor margin of the thorax is 

 rounded. C. Pens7jlvanicus DeGeer Jl

 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. 

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

 Sprague has reared the larva of T. hilineatus 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 the}'^ are expanded. 



Malachid.e Redtenbacher. This small group, often united 

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

 tenme being inserted on the sides of the front, and by the body 

 in some genera being furnished with soft extensible vesicles, 

 while the abdominal segments are in part membranous. Mala- 

 chius and its allies are of small size. Some of them resemble
