PRIOTOMA. 
Priotoma, Gorham, Biol. Centr.-Am., Coleopt. i, 2, p. 350 
(1886); Proc. Zool. Soc. Lond. 1898, p. 327; Pic. 
Cat. Anobiidae, p. 72 (1912). 
Eutylistus, Fall, Trans. Am. Ent. Soc. xxxi, pp. 212, 264 
(1905). 
The species referred to Priotoma simply differ from 
Caenocara, Thoms., in having the eyes feebly excised, and 
the body more regularly convex, due to the obliteration 
of the latero-submedian callosities of the elytra. Byrrhodes, 
Lec.,1 type B. setosus, Lec., again, is said by Fall to differ 
from Hutylistus in one character only, viz. in the sharp 
striation of the elytra. Some of the Central American forms 
with very finely striate elytra, e.g. P. tenwistriata, Gorh., 
etc., would therefore be almost as well placed in Byrrhodes, 
Lec.; these insects, however, are connected with the 
typical Priotoma, type P. quadrimaculata, Gorh., by inter- 
mediate forms. It is probable that, sooner or later, the 
whole of them will have to be included under Caenocara, 
C. flohri forming the connecting link between that genus 
and Priotoma. Fall enumerates eight species of this genus 
from the United States, and says that the European Dorca- 
toma dommeri, Rosenh., also belongs to it. The six now 
known from Central America, and the one before me from 
the Lesser Antilles, may be tabulated thus :— 
a. Antennae 11-jointed; elytra spotted, 
the two submarginal striae abbreviated 
anteriorly : body veryconvex . . . quadrimaculata, Gorh. 
b. Antennae 9-jointed. 
a'. Elytra with two submarginal striae, 
the subhumeral stria wanting. 
a*, The two submarginal striae not 
abbreviated anteriorly. 
a®. Elytra coarsely, confusedly 
punctate, and obsoletely striate 
throughout : body bluish-green

1878, requires a new name: Byrrhopsis is here substituted for it.
