In the Mexican fauna the species of the family Throscidje show 
nothing in common. In onr fauna Throscus sens. lat. is represented 
hy thirteen species, and in ^Mexico by five, while Drapetes contains 
twenty-six in ^Mexico and hut four with us, in addition to which 
Lissomus has twelve Mexican species, and is totally unknown in our 
fauna. Pactopus makes a closer approach to the Eucnemidse without 
having any parallel in Mexico.

There has recently a])peared from the able hands of Dr. Candeze 
a work entitled, “ Catalogue Methodique des tllaterides connus en 
1890,” which will have great value to those interested in the study 
of that family. In it all impertinent synonymy has been omitted, 
only such being given as has not already obtained sufficiently wide 
circulation. But little has been observed worthy of correction in 
reference to our species, except that Megapenthes granulosus Mels, is 
on ]). 98, while its male is found on p. 190 as Ludius limbalis Hbst. 
Our Betarmon higeminatus Rand, has been omitted. The results of 
my studies of Cryptohypnus are included in the list, although I have 
slightly modified the arrangement of the species since my communi- 
cation to him.
