NEMATUS PUNCTICEPS. 59 



than the mesothorax, vertex finely punctured, covered with short 

 down, shining ; clypeus and labrum white, the former with a slight 

 emargination. Thorax black, covered with short down; the tegulae 

 white. Legs white, the basal half of the two anterior, and nearly the 

 whole of the posterior femora, the apical fourth of posterior tibiae and 

 the apical three-fourths of the posterior tarsi black. Wings hyaline, 

 the costa and stigma sordid white ; the first transverse cubital nervure 

 is absent ; in the second cubital cellule is a horny point ; the third 

 cellule is almost a parallelogram ; the second recurrent nervure is 

 received immediately in front of the second transverse cubital. Abdo- 

 men black, a little longer than the thorax and head, broad, the apex 

 acuminate ; cerci small, thin, the saw projecting, broad. 

 Length If lines. 



In the absence of the first transverse cubital ner- 

 vure, in the punctured vertex with invisible suture and 

 pentagonal area, this little species agrees with those 

 of the ruficornis group, but the clypeus is slightly 

 notched and white, and the antennae do not taper so 

 much towards the apex. Judging from the descrip- 

 tion, it must be a very close ally of N.filicornis, Thorns, 

 (which Thomson states agrees with N.fulvipes and its 

 allies, but differs in the emarginated clypeus, while the 

 antennae resemble those of Blennocampa) , but it differs 

 from that species in many points. Thus Thomson 

 gives the antennae as being " breves, corpore dimidio 

 evidenter breviores," while in hibernicus they are 

 decidedly longer ; the third joint, too, is not one-third 

 longer than the fourth, nor can the wings be said to 

 be " lenissime fumatis;" filicornis, again, has the middle 

 tibiae marked with black and the tarsi testaceous, the 

 tegulse, being " fusco-testaceous." 



Rare. County Wicklow (King), Norwich (Bridg- 

 man).
