491. Phymatocera sp.. West Cliff, May 19, by sweeping Thermopsis ; a black 



species. 

 In the case of the Messa, it is difficult to say which name should be used. 

 Only the larva was described as salicum, and when I published the 

 notes in "Psyche" I supposed Mr. Ashniead would use the same name 

 for the imago. A fuller description of the larva than that formerly 

 given is appended.®
