sively on Quercus rubra. It is a dull olive and red-brown species, 

 rather less hairy and with the characteristic color pattern more clearly 

 defined in the female than is found in that sex in the closely allied 

 species O. pnbcsccns Emmons, with which it is often confounded. 

 The latter is commonly taken in this neighborhood during the same 

 period as the former, but usually on Quercus velutina. The obscure, 

 often obsolete, color pattern of the females, the denser pubescence, 

 and much smaller size, readily distinguish pubesccns from salamandra. 

 The males of both species differ from the females in being slightly 

 smaller, darker, more shining, and more distinctly arcuated with a 

 pale vitta from the humerus back to the mid-lateral margin of the 

 pronotum. These two species offer no real difficulties, although it is 

 significant of the variability of the color markings that Mr. VanDuzee 

 refers to salamandra as the duller of the two, whereas in my expe- 

 rience it is the brighter, at least in the female sex. 



In this connection, however, it seems worth noting that in Florida, 

 and at least as far north as south-central North Carolina, typical 

 pubcscens is replaced by a form somewhat smaller and more slender 

 and in which the ground color is light green more or less suffused 

 with pinkish, instead of the usual sordid dull olive brown, and the 

 space between the mid-dorsal and apical vittae is a bright pinkish red. 

 This form I would designate as 0. pubcscens var. australis,. n. var., 

 with type female and allotype male from Southern Pines, N. C, taken 

 in May (A. H. Manee), the former in collection of Chris E. Olsen of 

 this city, the latter in my own. Paratypes are in the above collections 

 and in that of Mrs. Slosson, those of the latter having been taken at 

 Jacksonville, Fla. 



The next species to be considered is O. flaviguttula Goding. In 

 most collections to which I have had access I find it unrecognized. 

 Nor is it treated in the literature other than by way of listing since 

 Dr. Goding described it in 1894; with one notable exception. In a 

 paper published in the December, 1917, number of this Journal enti- 

 tled " The Genus Ophiderma Fairm." by Gibson and Wells, the species 

 is included in a key, and in the same paper is again referred to in a 

 descriptive and distributional note. Dr. Goding's description was 

 based on a single female taken in Illinois; and in view of the unavail- 

 ability of his collection containing his types, and the fact that the 

 description closely corresponds to many specimens of pubesccns, com-
