2G6 ADDITIONS AND CORRECTIONS. 



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

 nomyia, Dunieril, was published in 1801 ; in giving the date 1798, I was 

 led into error by the obituary notice of Dumeril, in the Aunales de la Soc. 

 Entom. de France, I860, p. 653, where that date is given. 



The name Telanoc&re 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). Schiiier is again in error here. 



On page 223, in the note 47", sixth line, for Latreille, H. N., etc., 1804, 

 read Latreille, Precis, etc., 1796. 



Ill, p. 17. Family Blepharoceridae. 



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

 of the Blepharocerida3, and have come to the conclusion, that B/eph. yose- 

 mite should rather be considered a Liponeura, 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 uber B/epharoceriden 

 (Deutsche Eutomol. Mouatschr., 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 

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

 remarkable for having the venation exactly like Lijioneura 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 

 the venation of this species, which I call Bl. ancilla, with that of L. 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. 



Blepliarocera aiicilla, n. sp. ; female ; Gray ; thoracic dorsum 

 brownish, with paler longitudinal lines ; abdomen brownish, incisures 

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

 brownish-yellow ; tips of femora brownish ; tarsi brown ; knob of halteres 

 infuscated ; wings subhyaline ; veins brownish-yellow ; venation similar 

 to that of Lipon. yosemite. Length, 7 mm. 



Hab. California (collection of Mr. Bigot, in Paris). 



The antennae have nothing unusual in their structure ; they are a little 

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

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

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

 short-cylindrical, becoming gradually shorter towards the tip ; the last
