Sect. DERELOMIDES. 
The Derelomides are widely separated from the Erirrhina by both Lacordaire and 
Leconte, notwithstanding the close affinity of Derelomus and Phyllotrox, the latter 
being referred by them to the Eugnomides. 
DERELOMUS. 
Derelomus, Schéuherr, Curc. Disp. Meth. p. 235 (1826) ; Gen. Cure. ii. p. 629; Lacordaire, Gen. 
Col. vii. p. 10. 
Notolomus, Leconte, Proc. Am. Phil. Soc. xv. p. 222 (1876). 
This widely distributed genus includes a few species, most of which are apparently 
found on palms, two of the North-American forms and one of the European, at least, 
attacking Chamerops. Notolomus is connected with Derelomus by intermediate 
forms *, the extent of separation of the anterior cox varying according to the species. 
1. Derelomus estriatus, sp. n. 
Oblong-ovate, rather broad, opaque, the elytra somewhat shining, thickly clothed with very fine short pubescence, 
luteous, the eyes black, the entire surface closely, minutely punctate. Rostrum eurved, rather stout, about 
as long as the prothorax; antenne inserted at a little before the middle of the rostrum, joints 2-7 of 
the funiculus short, increasing in width, 7 as wide as the club. Prothorax transverse, nearly as wide 
as the elytra, constricted in front, immarginate laterally, the sides gradually and arcuately converging 
from a little before the base to the apex, the base feebly bisinuate. Elytra almost without trace of 
strie, Anterior cox moderately separated, the intercoxal portion of the prosternum parallel-sided, but 
widening posteriorly. 
Length 23, breadth 14 millim. 
Hab. Mexico, Jalapa (f/ége). 
One specimen. 
9. Derelomus palmarum, sp.n. (Tab. VIII. fig. 24, 24a, 0.) 
Oblong-ovate, opaque, the elytra somewhat shining, very finely and closely pubescent, luteous, the eyes black, 
the entire surface closely, minutely punctate. Rostrum moderately curved, about as long as the prothorax ; 
antenne: inserted at (@) or before (¢) the middle of the rostrum, joints 2-7 of the funiculus short, 
gradually increasing in width. Prothorax transverse, nearly as wide as the elytra, immarginate laterally, 
constricted in front, bisinuate at the base, the sides gradually and arcuately converging from a little before 
the base tothe apex. Elytra obsoletely striate towards the base. Anterior cox separated by a triangular 
process of the prosternum, which is reduced to a thin lamella posteriorly. 
Length 2}-23, breadth 1 millim. (¢ Q.) 
Hab. Mexico, Manantial (Flohr); Panama, Volcan de Chiriqui (Champion). 
Found in plenty on the flowers of a small palm in Chiriqui; a single specimen only 
seen from Mexico. Very like D. estriatus, but a little narrower, the elytra faintly striate 
towards the base, the anterior coxee more approximate. 
* Leconte also states that the tarsal claws are broadly toothed, but in a specimen of his V. bicolor before 
me I fail to see the tooth.
