yet from Mexico ; others probably remain to be discovered in the northern part of that 
country. 
The different species are found under stones. 
1. Husattus nitidipennis. (Tab. III. fig. 22.) 
Eusattus nitidipennis, Lec. Ann. Lyc. New York, v. p. 188 (nota)'; New Sp. Col. p. 112; Horn, 
Rev. Ten. N. A. p. 294. 
Hab. Mexico, Jalapa! (Haldeman), Guanajuato (coll. Sallé). 
In this species the elytra are inflated, rounded on the sides, and not margined, 
broadest a little before the apex, and covered with fine shallow widely scattered punc- 
tures ; the surface glabrous and slightly shining. 
2. Kusattus brevis. 
Smaller, shorter, and duller than Z. nitidipennis; the thorax more rounded at the sides; the elytra shorter and 
less inflated, irregularly wrinkled and covered with scattered coarsish punctures, rarely obsoletely costate ; 
the epipleure formed as in that species. The upper surface in fresh specimens covered with a sort of 
short pubescence. 
Length 10 millim. 
Hab. Muxico, Esperanza (Hége). 
Captured in great abundance by Hoge. 
3. Husattus dubius. 
Eusatius dubius, Lec. Ann. Lyc. New York, v. p. 182"; Horn, Rev. Ten. N. A. p. 2947. 
Hab. Nortu Americ, deserts of the Colorado and Gila rivers! 2. 
Found just on our northern boundary. 
4. Kusattus depressus. (Tab. IV. fig. 1.) 
Broad oval, depressed above, somewhat parallel, dull black, glabrous. Head coarsely and closely punctured, 
the epistoma very feebly emarginate in front ; prothorax comparatively rather long, rather broad in front, 
the anterior angles prominent but obtuse, the sides feebly sinuate before the base, smooth ; elytra some- 
what parallel, the disc depressed, strongly depressed transversely at the base, rounded on the sides, the 
epipleure gradually and broadly widening to, and very sharply defined at, the base, the dividing carina 
meeting the hind angles of the thorax and visible from above, with a few scattered fine shallow wrinkles 
or impressions, almost smooth ; anterior tibia produced into a very stout blunt tooth at the outer apical 
angle, rather coarsely punctured above; prosternum coarsely punctured, horizontal, the apex broad and 
rounded. 
Length 13 millim. 
Hab. Mexico, Alamos (Buchan-Hepburn). 
One example. Ofa different facies from any other Eusattus known to me.
