the 2nd segment very large. Although Foerster made 

 the genus, I am not aware that he has described any 

 species of it. Brischke has described one {T. femorcdis). 



Aptesis Foersteri, n. s. 



Eufus ; capite, metathorace, abdomineque, segmento 

 1° ex parte, 5 — 7, nigro. Antennis rufo-fuscis, basi rufis. 



Head subquadrate ; antennae a little shorter than the 

 body ; basal joints of flagellum cylindrical, elongate ; 1st 

 joint about four times as long as wide ; 2ncl a trifle 

 shorter ; the remainder decreasing gradually to the apex ; 

 head much wider than the thorax. Thorax rather nar- 

 row, somewhat elongate ; metathorax rather shorter than 

 the mesothorax ; metathorax without areae, but a distinct 

 posterior transverse line, the slanting part with postero- 

 medial area decidedly, though somewhat feebly, defined. 

 Abdomen elongate, ovate, much wider than the thorax, 

 nearly twice as wide ; apex of 2nd segment the widest 

 part ; 3rd, 4th, and base of 5th the same width ; all the 

 segments, except the 1st, transverse, this narrow, about 

 twice as wide at the apex as at the base, tapering ; 

 tubercles distinct, rather more than twice as long as the 

 width of the apex ; aculeus a little longer than the 1st 

 segment, or about one quarter the length of the abdomen. 

 Wings reaching beyond the metathorax. 



Head black ; mouth reddish ; antennae reddish brown, 

 first three joints pale red ; thorax red ; metathorax black. 

 Abdomen red ; 1st segment brownish in the greater part 

 of the middle ; 5th and following segments dark brown ; 

 aculeus red ; apical one-third brown ; legs red ; apex of 

 hind femora stained with brown ; apical joints of all the 

 tarsi blackish ; wings with a faint smoky spot in the 

 region of the stigma, and a similar colom-ed band be- 

 tween this and the base. Long. 3*5 mm. 



One female. Brundall, Norfolk, on September 15th, 

 1881 ; by sweeping. 



I have put this insect in Foerster's genus Aptesis, al- 

 though it differs from some of his characters. Of this genus 

 he says the joints of the antennae are short and stout, but 

 in this insect they are just the reverse ; he also says the 

 antennae are always tricoloured, but in a note, except in 

 A. hemiptera when they are bicoloured, as in my insect; 

 the antennae are more like Agrothcreutes, but the 4th 

 joint of hind tarsi is not notched at the apex as in 

 that genus.
