140 BOARD OF A(5RICULTURE. 



Calosdma cdliduni, tlie hot, or glowing 

 calos6ma, (figure 16,) was so named by 

 Fabricius, probably on account of the appear- 

 ance of tlie elytra which seem like the per- 

 forated cover of a glowing furnace, being 

 punctured with six longitudinal rows of sunken 

 metallic spots of a brilliant red. This insect 

 is much more common in the eastern part of 

 Massachusetts than the last described, and is 

 '^' of a smooth shining black, with a large head 



and powerful jaws ; a short and broad thorax somewhat turned 

 up at the margin ; and elytra finely lined, and punctured as 

 described above. It measures over .90 in length, and .45 in 

 breadth. 



The genera Eldphrus of Fabricius, meaning light or nimble, 

 and Nuliopliihis* 0^ Dumeril, meaning moisture-loving, are of 

 much smaller size than the last group, averaging from .20 to 

 .35 in length. The first is represented in this State by one not 

 uncommon species, the Eidphrus ruscdrius of Say, a name taken 

 from the Ruscus aculeatus of Linnasus, or " butcher's broom." 

 Tbis insect is of a dark brownish green, a little bronzed, about 

 twenty large, round, impressed purple spots on each elytron, and 

 tliree raised tubercles of a squarer form on each side of the 

 sutui'C ; the eyes are quite prominent and the appearance of the 

 insect is much like that of a small and thick tiger-beetle, but the 

 elytra are much broader at their base than the thorax. It 

 measures over .3 in length, according to Say, a specimen in 

 the State Cabinet, however, is scarcely .26 in length, and .12 in 

 breadth. Tlie Notiuphili are smaller and more slender than 

 the Elap/iri, and of a polished brown or black with bronze lustre. 

 They, like the preceding, are found on the muddy banks of 

 streams, and other damp localities, and are exceedingly active 

 in their motions. 



Clihrnius of Bonelli, ( Cldaina in Greek signifies a woollen 

 cloak,) is represented here by seven or eight species, of which 

 ChUrnius ser'iceus of Forster, or the " silky ground-beetle " is 

 the handsomest and most common. The head and body 

 beneath are black, the feet and antenna) light brown or 

 yellowish ; the head and thorax, above, shining green with very 

 fine ))uncturcs, the latter has a short longitudinal impressed
