184 ENTOMOLOGICAL NEWS. [June, 



convex, wider than long, lateral fovea very large, the median one small, 

 <leep and circular. Elytra with the shoulders broad, rounded, the discal 

 lines slightly impressed; first dorsal segment four times wider than long, 

 border widely reflexed, the carinae sharp, divergent, short more than one- 

 fifth of the segmental width apart, disc at the base each side deeply 

 depressed. 



Male and female, East AUeghanies, Jerome Schmitt. It ranges 

 near R. cribricollis. 



In order to correct certain odd presumptions, I do here, for 

 the last time, give the diagnoses of the following species : 



R. gemmifer. — Pronotum with small, evenly distributed punc- 

 tures, abdominal carinulae very close, hardly visible beyond the 

 elytra. 



R. canadensis. — Pronotum coarsely punctured, in the 9 

 smaller, carinae sometimes almost as long as the segment, close 

 at the base and divergent. Elytra and dorsum punctulate. 



R. cribricollis. — Pronotum coarsely punctured almost variolate, 

 carinae less than one-third of the segmental width apart, slightly 

 divergent. 



R. puyicticollis. — Pronotum evenly, sharply punctured, carina 

 much more than one-third apart. R. divergens and radians 

 have the pronotum impunctate, carinae close at the base. 



R. divergens. — Carinae short, elytra unevenly punctured 1.2 

 mm. long. 



R. radians. — Carinae one-half the length of the segment, 

 elytra impunctate, 1.5 mm. long. 



R. inopia ? Casey. — First insufficiently described, then com- 

 pared with Nisaxis tomentosa, then the fabricant joined it to 

 rubicunda, still later to puncticollis, and finally ruminating the 

 same again disgorged it identical with liitoralis. 



Casey evidently does not know, what he is about in trying to 

 save ' ' inopia Cas. ' ' 



Bryaxis labyrinthea Cas. is, indeed, very closely allied to B. 

 hitermedia, which also comes from New York, so closely that 

 there is hardly room for a variety. 



Rybaxis mystica Cas. a variety of conjuncta, described by me 

 as R varicornis^ 



Tychus testaceus Cas. formerly sworn to be different from T. 

 minor, which is really the truth, is now again unsworn and said 

 to be identical, probably in order to make two n. sp. , which do
