Cephahia Panzer. 

 Basal nerviire joining the costa either free or at the base of the cubitus, 



never on the cubitus Ccejiolyda Konow.

Pamphilius Latreille. 

 Basal nervure joining the costa free from or at the base of the cubitus, never 



joining the cubitus free from the costa Kelidoptera Konow. 



Bazal nervure joining the cubitus free from the costa i. 



I. First flagellar joint more than half as long again as the 



second Anoplolyda A. Costa = (Bactroceros Konow).

Acantholyda Kincaidi Rohwer. — Itycorsia Kincaidi Rohwer, Can. 

 Ent., p. 91, t 910. 



The placing of this species in Itycorsia was a mistake. It belongs to 

 Acantholyda, and is allied to margiventris (Cresson), but may be separated 

 from that species by the dark red tibiae and tarsi, and in having a pale 

 spot on the pleura. 



Cephaleia Hopkitisi, n. sp. — Superficially resembles Cephaleia 

 fulviceps Ruh., from New Jersey, but the postocellar area is nearly 

 quadrate, not wider than the cephal-caudad length, and the legs below the 

 coxge are rufous, not black. 



Male: Length, 11.5 mm, Lateral supraclypeal areas shining, 

 impunctate ; clypeus and supraclypeal area broadly rounded, not carinate; 

 postocellar furrow wanting; ocellar furrows nearly parallel; antennae 

 2i-jointed, third joint nearly as long as the three following; middle area 

 of the mesonotum punctured, the sides impunctate; hypopygidiiim wider 

 than its cephal-caudad length, pointed, apically and triangularly depressed. 

 Black ; head, except a l.irge quadrate spot from antennae to occiput and 

 apical part of mandibles rufous ; legs below coxre the colour of head. 

 Wings dusky hyaline ; venation black.
