NOTES ON SOME CLERID> OF MIDDLE AND 



NORTH AMERICA, WITH DESCRIPTIONS OF 



NEW SPECIES. 



BY A. B. WOLCOTT. 



The twenty-four new species described in the following paper, 

 together with the notes on others, a few of which are species new to 

 our faunal region, embody the partial results of spare moments de- 

 voted to a study of this family for several years. 



It is hoped that the details figured in the plate, which were pre- 

 pared with some care, will assist the student to a proper understand- 

 ing of the structure of the parts, and that the tabulating and re- 

 describing of the species of Monophylla, Aulicus, Trichodes, and 

 Cregya will render them recognizable and awaken interest in these 

 beautiful but much neglected insects. 



To the many friends and correspondents who have loaned or 

 given to the writer, in many instances, their choicest captures in this 

 family his heartiest thanks are due. Especially does the author feel 

 under deep obligations to Prof. H. F. Wickham, who from time to 

 time has very generously placed at the writer's disposal the rich and 

 extensive Clerid material taken by him on various expeditions to 

 Mexico and the western parts of North America.

The term Elasmocerus was proposed by Dr. LeConte for the sup- 

 posedly preoccupied generic names Monophylla Spinola and 

 Macrotelus Klug, which are not, however, under the one letter rule, 

 homonyms of the earlier described generic terms Monophyllus Leach 

 and Macroteleia Westwood. Under the one letter rule generic names
