and minutely punctnlate, almost coriaceous ; the latter not mar- 

 gined ; post-scutellum elevated into a tubercle. Metathorax hori- 

 zontal, truncated behind, reticulato-rugulose, carinated in the 

 middle, hardly bidenticulate. Abdomen deplanato-cylindrical, 

 broader posteriorly, obtuse (hence probably a <?), sculptured as 

 usual, and with two inchoate basal carinse ; anus not perforated. 

 $. Length, 1|; wings, 2^ lin. 



Very like siilcatus, Nees, ^ , but distinguished by 

 wanting the anal fissure. The sex can onl}^ be inferred 

 from the antennae (which are not quite conclusive) and 

 from the obtuse abdomen, which is not likely to be that 

 of a ? . 



The single specimen was bred by W. H. B. Fletcher 

 from Elachista atricomella, Staint., (;r E. luticomella, 

 Zell.

 Black ; abdomen immaculate ; i)alpi black ; fore tibise and tips 

 of the fore femora testaceous ; or all the tibiae like the tarsi, 



'■'■'■ The following is another large species, the ^ of which exhibits 

 the anal fissure. As the ? has not been before noticed, it may be 

 useful to describe it here : —

Black, fore femora at the apex, fore tibiae, intermediate tibias on 

 one side, or entirely, and the hind pair in the middle, testaceous. 

 AVings subliyaline, stigma and nervures fuscous, parastigma and 

 praebrachial testaceous, squamulse black ; radial areolet twice as 

 large as the stigma, 3d abscissa slightly curved, radius of hind 

 wings straight except at the base. Head minutely rugulose, vertex 

 transverse, cheeks dilated. Antennge ^ broken (2o-jointed according 

 to Reinhard) ; of the J 27-jomted in one specimen, broken in the 

 other. Mesothorax jiunctate, shining in Iront, reticulato-rugose 

 behind ; scutellum shining, punctulate. Metathorax dull, rugose, 

 reticulated, bidentate. Abdomen with the usual sculpture, that of 

 the (^ longer than the head and thorax, subcylindrical, apical 

 fissure three times broader than its length, mai'gined, ciliated ; of 

 the 3^ shorter, roiinded at the sides, and wider behind. Terebra 

 and valvula ventralis visible, prolapsed. $ $. Length, 2^; 

 wings, 5 lin. 



Equal in size to C. inanlhis. The sexes correspond in all 

 respects, and the antennas of the $ show that C. erosus, Schiiff., 

 F. G., cliii., 9, which has IG-jointcd antenna', does not belong to 

 this species. 



A male and two females were taken by Sharp in the Sierra 

 Nevada.
