heikertingeri. The present writer recently has exammed specimens 

 from Dominica and St. Lucia that are probably this species. The 

 writer at once recognized the relationship of these specimens to the 

 other West Indian species described under Pseudoepitrix although, in 

 E. heikertingeri (also a larger species), the male characters are very 

 long antennae, very swollen frontal tubercles, and two well-developed 

 tubercles in the lower front of the face — all characters to be found in 

 E. facialis. 



In all the West Indian species the head is long, as in E. facialis. In 

 P. longicornis, described from a male only, the antennae approximate 

 those oi facialis. In P. suffriani the frontal tubercles over the antennae 

 are very swollen, as in facialis. To a slightly less extent this may 

 also be true in P. trinitatis, as shown in Mr. Bryant's drawing (the present 

 writer has not examined the type). In the remainder of the West 

 Indian species (hqffmani, hispaniolae, punctatissima, hottensis, jamai- 

 censis, and tetraspilota) none of these striking male characters so far 

 has been observed, but it is evident that all of these species belong to 

 the genus Exoceras, rather than to Pseudoepitrix. 



The West Indian species are all smaller than E. facialis, and all 

 very similar, forming a homogeneous group. Several have been 

 collected on tree ferns. Mr. Bryant records trinitatis as destroying 

 young fronds of the fern Adiantum tenerum. These species do not 

 have the long elytra common to Pseudoepitrix and, unlike this genus, the 

 anterior coxal cavities are open. The head in Pseudoepitrix is normal, 

 not elongate, and there are no traces of tubercles on the lower front 

 nor enlarged tubercles over the antennal sockets. 



Two new species of Pseudoepitrix are included in this paper to 

 illustrate the differences in the two genera. Drawings have been 

 made of Exoceras facialis Jacoby (fig. 25), E. suffriani (Jacoby) (fig. 22), 

 and what is probably E. heikertingeri Bechyne (fig. 24). 



Sidfaya, new genus 



Small, between 2 and 4 mm. in length, ovate, convex, shining black, 

 with coarsely and confusedly punctate prothorax and elytra, head 

 with groove extending down from eye to frontal tubercles, inter- 

 antennal area broad, somewhat produced, front below slightly de- 

 clivous. Antennae not extending much below humeri, first two 

 joints swollen, third to sixth slender and subequal, joints seven to 

 eleven much thicker but not much longer. Prothorax twice as wide 

 as long with lateral sides slightly angulate, with anteriorly a prominent 

 oblique angle, middle of margin sharply rounded and at basal angle a 

 well-developed tooth, disc without basal depression and strongly 

 punctate. Elytra widened slightly behind, convex, with prominent
