In America Triv/iodcs nuttalU is not rare in August ujion flowers of Spirtna alba, but its larval liabits have not been studied. It is about of an inch long, and somewhat resembles T. apiurius in color and markings. The genus AuKciis, which has the apex of lioth labial and maxillary \ jialpi dilated, is fminil on the western coast of North America, as is also the very slender Pen7i//)/is carbonari us, in wliicli the jiosterior thighs are elongated. The larv;e of TiUiis uiiifa-'^rhitus, a European species, li\e in dried grape twigs, jireying upon larvaj of Auaspis maculata and Apate ; and finally ])upating in the twigs. It is ])robable that T. collaris, from Georgia, has analogous habits. The faniilv of is often united with the next succeeding family (Lani- pvi-idie) from the species of which the members of this family differ in having only six free venti'al segments, and in the insertion of a sejiarate piece between the front and the labruin. The genus MalacJdus, and a few of its allies, has excited the attention of many observers on account of its protrusion of two evaginable ]irci- cesses from each side. In 3/a/achitis aneus each anterior process is trilobed, and is pushed out on each side from lieneath the anterior angles of the prothorax; each posterior process is bilobed and originates between the metathorax and first abdominal segment. These jirocesses are of a deli- cate red or reddish-yellow tissue; they were shown by Dr. H. Liegel to be evaginated by tilling with the blood or liody- fluid of the insect, and to be retracted by muscles within them. The function of these organs is unknown. 3fa1arliius aneus, the beetle just mentioned, is about of an inch long ; the anterior angles of its pr
