THE CANADIAN ENTOMOLOGIST. 75 



I know of but one somewhat variable species, described by Bruner as 

 Tlirincus (?) maciilatus. Mr. Bruner has kindly sent me types of this 

 for examination. 



The tribe Thrincini has not been found in America. The second 

 species which Bruner has referred doubtfully to Thrincus, viz., T. ariilus, 

 belongs to Heliastus, a genus of Oedipodini in near vicinity to the 

 Thrincini. The species described by Thomas under the name Thrincus 

 californicus also belongs to Heliastus. 



Among the Oedipodini, Mestobregma Scudder and Trachyrhachis 

 Scudder are synonymous and the former has priority. 



In Psyche (vi. 265) I pointed out that my Leprus ingens from Cali- 

 fornia belonged to a new generic type, for which I now propose the name 

 Agymnastus (uyr/vj-iurTos^) in allusion to its clumsy inactivity. It is most 

 nearly allied to Leprus Sauss., but differs from it in its more bulky shape, 

 due largely to the exceptional breadth of the mesosternum, its abbreviated 

 organs of flight, which do not wholly conceal the abdomen when at rest, 

 and the presence of a subcostal taenia reaching the base of the wings 

 from the transverse fascia common to both genera ; the posterior process 

 of the pronotum also in rectangulate instead of rounded subacutangulate, 

 and the intercalary vein of the tegmina is more or less obscure proximally 

 and only a little nearer the median than the ulnar vein ; the upper and 

 lower carinas of the hind femora, and especially the lower,are subfoliaceous. 



One of the genera of our Tryxalinse has been very much named. It 

 was first described by me under the name Aulocara, males only of which 

 were seen. Very shortly afterward I redescribed it, from the female only, as 

 Oedocara. A few years ago Brunner renamed it Coloradella, and recently 

 McNeill has given it the name Eremnus ; Aulocara of course has priority? 

 and the species on which it was founded proves, as Bruner has already 

 pointed out, to be identical with Thomas's StauroJiotus EUiotti. The 

 genus under the name Oedocara was included by Saussure in the Oedip- 

 odinae and by Brunner (as Coloradella) in the Tryxalime, an excellent 

 illustration of the difficult definition of these two sub families. 



Some years ago, in Psyche, V., I attempted to show that certain 

 genera that had been referred to Tryxalin{e should really be placed in the 

 Oedipodiuc'e. I now think I was mistaken, at least as regards all the genera 

 found in our own country, and would follow Brunner in placing them in 

 the Tryxalinpe. It was partly owing to my statements that Mr. McNeill 

 has rejected them from his recent Revision of the Tryxalinge.
