SUPHIS.—CANTHYDRUS. 5 
SUPHIS. 
Suphis, Aubé, Ie. Col. Eur. v. p. 208. 
This genus, at present, is only known by three species from South America and the 
Antilles. 
1. Suphis difformis, var. 
Suphis difformis, Sharp, Trans. Roy. Dubl. Soc. n. s. ii. p. 268, t. ix. fig. 118. 
Hab. GuatEMaLA, Paso Antonio, 400 feet (Champion).—Sovutu AMERICA, from the 
Orinoco to Bahia. 
The Central-American specimens differ a little from the type in that they have the 
joints of the antenne less elongate; but they agree in this with an individual from 
Santa Rita, Brazil. I have not been able to distinguish the sexes. All the individuals 
have the basal joint of the front foot very large. 
CANTHYDRUS. 
Canthydrus, Sharp, Trans. Roy. Dubl. Soc. n. s. ii. p. 8388 (1882). 
The species of this genus are numerous, forty or fifty being at present known; and 
they occur in all the warmer parts of the two hemispheres, with the exception of some 
of the Pacific islands. 
1. Canthydrus simplex. (Tab. I. fig. 3.) 
Subrotundatus, convexus, nitidus, testaceus, elytris castaneis, obsolete punctatis; prosterni processu longitudi- 
naliter depresso ; coxarum laminis parce punctatis. 
Long. 1 lin. 
Hab. Guatemata, Paso Antonio, 400 feet (Champion). 
This little insect is no doubt closely allied to the Brazilian C. rotwndatus, with which 
I am unfortunately unable to compare it. No serial punctures can be detected on the 
wing-cases. The central elevated portion of the metasternum is more densely and 
coarsely punctate than are the coxal lamine ; the latter at their common suture behind 
are a good deal depressed, and the coxal cavities are slightly separated. 
The male has the basal joint of the front and middle tarsi more incrassate than it 
is In the female. 
2. Canthydrus varians. 
Breviter ovalis, convexus, nitidus, prothorace antice in medio elytrisque fuscis, his testaceo-signatis, crebre 
fortiterque punctatis ; coxarum laminis parce punctatis.

The colour of the elytra is sometimes nearly black, sometimes more dilute; the
