'I'hu family of Blephiiroceridae, as at 

 present known, includes about fifteen 

 species tif nematoceious Diptera, of 

 unusual interest to entomologists. This 

 interest is caused bv the raritv of speci- 

 mens in collections, by the miique 

 structuial condition of the larva, by 

 the slran;j;e, although as vet imperfectly 

 known, life histor\' anti haiiits, and 

 linally by the peculiar accessory vena- 

 tion anti suggestive structural character 

 of the moutliparts and *compoimd e\ cs 

 of the imagines. 



In the summer of 1S9S, Mr. R. W. 

 Doane, at that time collecting for me in 

 the vicinity of this University (Stan- 

 ford), took two females and a male of 

 a Bleph^uocerid species. I have only 

 recently given these specimens any 

 attention other than the rather unkind 

 one of removing the heads of two (the 

 male and one female) in order to study 

 their moutliparts. A recent examina- 

 tion of the specimens reveals the fact 

 that they are representatives of an unde- 

 scribed species which may be assigned 

 to Low's genus Liponeura (.Stett. Ent. 

 Zeit. 1S44, vol. v, p. iiS).

Tlie new species m:iv be described as

might be construed to be a basal antennal 

 segment; eyes broadly separated, and with 

 no indications of bisection, the facets being
