second recurrent to the inner nervure of the kicking areolet, elongate and 

 slender petiole, and concealed terebra render it distinct ; as do the black 

 posterior femora and antefurcal nervellus of our species.

A black and slender species with the mandibles ferrugineous, tegulae 

 white ; tibiae with the front, and apices of the black posterior, femora 

 fulvous ; hind tibiae hardly infuscate apically ; head and thorax coarsely 

 and strongly punctate. Length, 6-6f mm. 



It is a black and sparsely grey-pilose species with at most the meta- 

 thorax centrally bicarinate to beyond its centre, though not laterally ; the 

 stigma is narrow and very pale testaceous, emitting radius from be3ond its 

 centre ; radial cell narrow, etc. 



There are records from central Lapland in July, Prussia, Italy, France, 

 Gottingen, Hanover in June, and Schmiedeknecht finds it in the spring 

 by no means rarely in Thuringia. Limneria mandibularis was introduced 

 as British (Trans. Ent. Soc. 1887, p. 367) since Dr. Capron had taken at 

 Shere five specimens, now in my collection with one from Albert Piffard's, 

 probably from the same source; this was the year that Thomson synonym- 

 ised it with N. aberrans, and consequently we must suppose Bridgman to 

 have previously been ignorant of the species and to have incorrectly 

 named the male, which Fitch says was raised by Elisha (Entom. 1881, 

 p. 140) from Lavenia contiubatella. Capron's are almost the only known 

 indigenous examples, since I have not met with it and no local list men- 

 tions it, excepting a single male (Trans. Norf. Soc. 1894., p. 619) captured 

 in June at Earlham near Norwich. 



NEMERITIS, Holmgren. 

 Holmgr. Sv Ak. Handl. 1858, p. 104. 



Body very slender and strongi)- elongate. Head transverse and an- 

 teriorly subcircular, much broader than thorax ; vertex not narrow ; cly- 

 peus a little convex and apically subtruncate, with its lateral foveae small; 

 mandibles small and flavidous, peristomium not large ; eyes entin- and 

 clu'cks subbuccate. Anteiniae slender, filiform and longer than half 

 body, with scape usually pale beneath. Thorax longer than high, sub- 

 cylindrical and elongate ; metathorax gradually declived from base to 

 apex, which is always slightly produced beyond the hind coxal base ; 

 areola oblong and pentagonal, emitting costulae distinctly before its 

 centre ; petiolar area short. Abdomen elongate, narrow and towards the 

 anus compressed ; basal segment but little curved with no or obsolete 

 lateral sulci ; postpetiole hardly broader than petiole, with no lateral 

 scrobes ; second segment alutaceous and somewhat dull, longer than 

 broad and obviously than the third, apically dilated and generally with 

 its apical margin rufescent ; terebra elongately exserted, often as long as 

 abdomen, with the .spicula very slender. Legs slender, the hind ones 

 obviously a little stouter and longer, with the unequal ealcaria not elon-
