320 THE CANADIAN ENTOMOLOGIST. 



at tip, with small black dots arranged in irregular rows and with two 

 blackish angulated lines behind the middle. It breeds in the stems of a 

 slender cucurbitaceous vine {Melothria pendula) which grows over fences 

 and bushes in dense festoons. Mr. Schwartz took this species at Bay 

 Biscayne, and it may occur in the Bahamas and Cuba. 



Leptostylus tratisversatus. — This species breeds in stumps and logs 

 of the Mastich [Sideroxylofi pallidum). The larva lives entirely in the 

 bark, where it pupates in a cell, after the manner of a Urographis. 



Spalacopsis litiuin, Duv. — This species was taken abundantly in 

 April and in May on the dead vines of Melothria pendula, in the dead 

 stems of which both larvae and pupee were abundant. The beetle is ex- 

 ceedingly slender, varying greatly in size, and in length from .20 to .60 inch. 

 It occurs also in some of the Bahama Islands and likewise in Cuba, and 

 is thus described by Chevrolat [Tr.] : ^^ Etithuorus filiiin, Duv. — Filiform ; 

 head closely punctate, grayish-brown, with three obsolete pale lines ; 

 thorax linear, closely punctate, brownish-gray, with an obsolete pale line 

 on each side and down the middle ; elytra brown, variegated with macu- 

 lations, especially near the suture; the apex margined, obliquely truncate 

 and produced, longitudinally sulcate, closely and strongly punctate, 

 interstices elevated ; antennae and feet brown. Length, 8-1 1 mill.; width, 

 173-2 mill." (An. France, Series 4, Vol. II., p. 256.) Mr. Schwartz pre- 

 viously took this species at Bay Biscayne. Its occurrence north from 

 Lake Worth has not been noted, but the vine in vvhich it breeds extends 

 around the Gulf to Texas. The pertinacity with which it feigns death is 

 extreme, and till it moves it can scarcely be distinguished in the umbrella 

 from the broken vines. 



Hippopsis lemnistica. — Taken abundantly with the foregoing species, 

 but it breeds in the stems of other plants or weeds besides Melothria. It 

 extends westward around the Gulf and as far northward as Eastern Penn- 

 sylvania. 



Caryoboriis arthritictcs. — This species, as is known, breeds abun- 

 dantly in the seeds of the Cabbage Palm {Sabol palmetto). From about 

 one quart of the berries placed in a covered paper box I obtained more 

 than 100 examples. This species, however, breeds in the seeds of other 

 trees, as I raised once several examples from the seeds of the Coffee tree 

 ( Gymnocladus Canadensis). 



Platydema subquadratum, Mots. — While the Florida and Arizona 

 examples are considered as belonging to one species, yet they have a
