Ill all these cases Agassiz's Nomenclator gives the correct dates. Echi- 

 noiiiijia, Dumeiil, was published in ISOl ; iii giving tlie date 17S8, I was 

 led iuto error by the obituary notice of Dumeril, in the Annalesde la iSoc. 

 Entom. de France, 1800, p. G53, where tliat date is given. 



The name Telanocire appears for the first time in the same publication 

 of Dumeril's (1801), but is translated Tetanocerus in his Zool. Analyt., 

 1806. Latreille adopted it as Tetanocera in his Hist. Natur. des Crust, 

 et des Ins., Vol. Ill (1802). Schiner is again in error here. 



On page 223, in the note Ala, sixth line, for Latreille, H. N., etc., 1804, 

 read Latreille, Precis, etc., 1796. 



Ill, p. 17. Family Blepliaroceridae* 



Since my arrival in Europe I have had opportunities of a closer study 

 of the Blepharoceridse, and have come to the conclusion, that Bleph. yose- 

 mite should rather be considered a Lipoiieura, its broad front being in this 

 case a character of higher order than the differentiation of the facets 

 of the eyes in two portions (with larger and smaller facets). I pub- 

 lished this fact in an article entitled, Bemerkungen iiher Bl epharocerideti 

 (Deutsche Entomol. Monatschr., 1878, p. 405-416), in which many other 

 remarks, supplementary to Loew's Revision, etc., are incorporated. 



In looking over Mr. Bigot's collection in Paris, I observed in it an 

 undescribed Blepharocerid (a female), likewise from California, and very 

 remarkable for having the venation exactly like Liponeura yosemite, 

 although its contiguous eyes make it a Blepharocera. A deep groove 

 divides the eyes in two portions, but there is no strip without facets, as 

 in the two species of Blepharocera hitherto described. The identity of 

 tlie venation of this species, which I call Bl. ancilla, with that of Z. yose- 

 mite, would seem to prove that it is the venation, which, in this case is a 

 character of higher order than the structure of the front. Many such 

 discoveries would tend to obliterate the limit between the genera Blepha- 

 rocera and Liponeura.

 yellowish ; antennje brownish-yellow, brownish towards the tip ; legs

The antcnnoi have nothing unusual in their strurture ; they are a little 

 longer than the head, 14-joinled; first joint short, nearly of the same 

 length with the second, but a little stouter; first joint of the flagellum a 

 liale longer than the two following joints taken together ; the other joints 

 short-cylindrical, becoming gradually shorter towards the tip ; the la.<t
