172 THE CANADIAN ENTOMOLOGIST. 



irrorata, Godg., described first in Bui. 111. Lab. Nat. Hist., Vol. 3. It is 

 the only description ever published. No. 2133, labelled Telamona 

 concava, Fh., $? , and apparently identical with No. 12727, a male. There 

 is a beautifully coloured $ of this species in the collection of the Depart- 

 ment of Agriculture, light and dark blue-green. 



No. 3907 is Telamona trisiis, Fh., ? , and another smaller example 

 doubtless the same. With these is a coryli, Fh., 3*, which I believe to be 

 the same species as suggested by Van Duzee. 



No. 2152, labelled Ledra perdita and capra, Mels., is Centruchus Lic- 

 beckii, Godg. 



No. 6276, is Microcentrus caryee, Fh., $ , and No. 1S7S is $ . This 

 species was erroneously referred, by Fitch, to the genus Uroxiphus. 

 The female is about one-fourth larger then the male. 



No. 6926 is labelled Cyrtosia fenestrata, Fh., $ . It is the only 

 example I have seen that agrees with Fitch's description " tip of the 

 thorax reaching beyond the terminal cells of the elytra." In all the 

 examples in my own collection the tip of prothorax barely reaches the 

 terminal cells, while Mr. E. P. Van Duzee, a careful student and successful 

 collector, informs me that all the specimens he has seen agree with my own. 



No. 1 1764 is labelled Cyrtosia fuliginosa, $ , described and figured in 

 Emmon's valueless work on the Insects of New York. The dorsum is 

 dark-brown with an arcuated yellow stripe on each side ; legs yellow. 



No. 3038 is labelled Cyrtosia discoidaZis, $?; also No. 4837. 

 Described in Emmon's work. No. 1 1 763 is Cyrtosia pallidifrontis of the 

 same author and doubtless the same. 



No. w^ii = Cyrtosia macidifrontis, and No. 4536 = Cyrtosia cine- 

 reum of the author's. 



There are many other examples of this genus [Cyrtosia being pre- 

 occupied, I have given to this genus the name Cyrto/obus] in the collection 

 under various manuscript names, such as nigra, punctifrontis, tricineta, 

 etc., which may be distinct species, but I am inclined to the opinion that 

 they are variations of a single species and that species may be Van of Say. 



There are several examples of the genus Ophiderma in the collection, 

 under the manuscript names nigripennis, arquata, rectineura, flavigutiula, 

 bicincta, nigriventris, dimidiata, columbis, etc., which I believe are varia- 

 tions of not more than two species. 



In the collection are to be found examples of Platycotis 4-vittata, 

 Say, = 4-/ineata, Germ. It is a dimorphic species, as has been proven by 

 Prof. Riley and Mr. Ashmead, the anterior horn being present in the one 

 and wanting in the other. Both forms are represented in the Fitch 

 collection and in my own cabinet.
