of life. Its position was strangely misunderstood by Lacordaire, as Leconte has pointed 
out, who places it next the Asemini; it seems to me to belong to the same group as 
(ime. Ten species have been described, all, except two, from America, North and 
South, including the West Indies. —

S. cucujiformi (Say) affine; differt capite latiori, g 2 post oculos oblique et valde angustato. Pallide tes- 
taceum, capite thoraceque subtilius punctatis, illo linea verticis tenui vix impressa, hoc breviter quadrato

British Hownpuras, Belize (Blancaneaur); Nicaraeua, Chontales (Belt).—Soura 
AMERICA, Brazil (coll. Laferté). 
A specimen in the Sallé collection, agreeing perfectly with Chontales examples of 
H. castaneus, is named H. mexicanus, Thomson; and there can be no doubt it is 
really that species. The example on which H. castaneus was founded is from the 
Laferté collection and labelled “Brasilia”; it may be only a colour variety of the 
Guiano-Brazilian 7. batus (Linn.). 
3. Hammaticherus batus.

Cerambyx datus, Linn. Mus. Lud. Ulr. p. 69. 
Hab. Panama, Tolé (Champion).—Sovutu America, Trinidad !; Amazons, Pernambuco. 
The Panama examples are not so dark as those from South America, the elytra being 
brownish black; they are, to the same extent, intermediate between H. batus and 
H. mexicanus.
