The only parasite raised from this species was Ichneutes fiilvipes 

 Cress., determined by Mr. C. T. Brues. 



Thanks are due to Dr. A. D. MacGillivray for telling me this was 

 a new species. I had considered it to be orbitalis Nort., to which it 

 is closely related, but it may be separated from this species by the 

 following comparison : 



C. hebbianx n. sp. ?. 



1. Clypeus shallowly emargi- 

 nate ; lobes broad, obtusely 

 rounded at apex. 



2. Middle carina high, sharp, 

 longer. 



3. Middle fovea smaller, some- 

 what crescent-shaped. 



4. Frontal crest not so promi- 

 nent, very slightly broken. 



5. Stigma distinctly broader at 

 the base. 



6. Venation brown. 



7. Orbits not nearly so broadly 

 ferruginous, inner orbits some- 

 times black. 



C. bebbiancR n. sp. c?- 

 I. Antennae reaching beyond 



C. orbitalis Nort. $ . 



1. Clypeus deeply emarginate ; 

 lobes rather narrow. 



2. Middle carina low, short. 



3. Middle fovea large, subquad- 

 rate. 



4. Frontal crest prominent, 

 rather broadly notched in middle. 



5. Stigma not very broad at 

 the base. 



6. Venation pale brown. 



7. Orbits broadly ferruginous. 



C. orbitalis Nort. c?. 



1. Antennai not reaching be- 

 yond the basal plates ; apical joint 

 shorter than the preceding one. 



2. Middle carina broad and low. 



3. Interocellar furrow faint. 



basal plates ; apical joint longer 

 than the preceding one. 



2. Middle carina more promi- 

 nent. 



3. Interocellar furrow much 

 stronger. 



4. Orbits almost entirely black. 



5. Stigma black. 



4. Orbits ferruginous. 



5. Stigma white at base.
