TENTHRED0PS1S NIGRONOTATA. 153 



Tenthredopsis cordata (Vol. I, p. 104). 



Konow unites this species (== nassata, Thorns.), 

 microcephala,femoralis, and caliginosa into one species, 

 which he names Thomsoni. If he is correct in this 

 view it seems to me that no new name is required, but 

 that the oldest name, namely, cordata, Fourc, should 

 be used. He refers my S to Coqueberti (ignobilis), and 

 in this he is correct. 



The real 3 of cordata [Thomsoni, Knw.) I have 

 never seen. It is described by Konow as " rufescens, 

 capite et mesonoto magis minusve albo et fusco-macu- 

 latis ; segmento ventrali late et semi-circulariter emar- 

 ginato," the latter being a characteristic in which it 

 differs from the other species, the males of which have 

 the apex of the last ventral segment " rotundatum vel 

 leniter emarginatum."

Konow doubtfully refers this species to his T. elegans 

 (described in full, D. E. Z., xxx, 335), and I think the 

 two are identical. He describes elegans, "minor gra- 

 cilis, nigra ; albo picta ; pedibus et feminse segmentis 

 intermediis abdominis rufis ; tarsis posticis nigrican- 

 tibus; capitis clypeo albido sulphureo ; antennis tenu- 

 ibus, abdomen longitudine sequantibus. Mas : abdo- 

 mine fere toto nigro, segmento secundo dense punctato, 

 segmento ultimo ventrali apice rotundoto. Femina 

 capite, pronoto, pectore, coxis uberius albomaculatis 

 vel maxima parte nigris, cingulo rufo abdominis 

 interdum linea dorsali nigra interrupto. Long. 11 — 

 12 mm." 



There is no trace of white on the breast or pronotum 

 on nigronotata, and only a small white spot on the hinder 

 pronotum. The tarsi in elegans are described as dark, 

 not distinctly lighter before the apex. The antennas
