latter by the terminal article of the labial palpi 

 being large and triangular : in the Thaliadss this 

 article is cylindrical. There are various other 

 points of difference which separate Myas from the 

 above group. The following genera, Abaris, II a- 

 thymus of De Jean, and Strigia and Heteracantha 

 of Brulle, probably belong to Thaliadae ; as I am 

 totally unacquainted with their forms, I defer 

 giving a decided opinion respecting them. Laporte, 

 I find, places Myas in the family of Trigonotomidse, 

 to it belong four genera, viz. Myas, Lesticus, Tri- 

 gonotoma, and Catadromus, they certainly are all 

 allied to Paecilus. For reference consult Audouin 

 and Brulle, and the writings of Laporte.

 to the above authors, and to them they add Calathus, 

 which I detach.
