PALAOTHONA. 301 
PALEOTHONA (p. 377). 
Palzothona guatemalensis (p. 377). 
To the localities given, add :—Mexico, Rincon in Guerrero, Atoyac in Vera Cruz 
(H. H. Smith). 
2 (a). Palzothona elongata. 
Elongate, fulvous; the antenne (the first joint excepted), tibie, and tarsi black; the head and thorax fulvous ; 
* elytra dark blue, more or less closely and strongly punctured ; legs piceous. 
Var. Legs partly or entirely fulvous. 
Length 13-2 lines. 
Hab. Mexico, Tupataro (Sallé). 
Very closely allied to P. guatemalensis, but evidently distinct therefrom. Larger 
and much more elongate in shape; the antenne entirely black, or black with the first — 
joint fulvous ; the head and thorax impunctate; the elytra not swollen at the base, 
their punctuation very variable—in some specimens very fine, in others much stronger, 
and arranged in very close semi-regular rows. ‘The first joint of the anterior tarsi is 
dilated in the male. Four specimens. 
2 (s). Paleothona imitans. 
Below black; the head, the basal joints of the antenne, the thorax, and the anterior legs fulvous; thorax 
impunctate ; elytra violaceous-blue, strongly and closely punctured. 
Length 14 line. 
Head broad, impunctate, the eyes very large, the frontal tubercles scarcely indicated, the carina short and 
distinct ; antenne nearly extending to the apex of the elytra, the basal two joints and part of the third 
fulvous, the rest black, the fourth joint much longer than the third; thorax transverse, slightly narrowed 
at’ the base, the sides rather evenly but not strongly rounded, the surface impunctate, slightly depressed 
in front of the scutellum ; the latter black ; elytra gradually widened posteriorly, rather swollen at the 
base, strongly punctured in closely arranged rows; anterior legs and the base of the posterior femora 
fulvous, the anterior femora with a dark streak on their upper edge. 
Hab. Mexico, Xucumanatlan in Guerrero (H. H. Smith). 
Two specimens. In the strong elytral punctuation this species approaches P. guate- 
malensis. It differs from that insect, however, by the antenne being much longer, 
and with the fourth joint distinctly longer than the third ; the thorax evenly rounded 
at the sides (instead of being considerably widened at the middle); and the legs 
differently coloured. 
3 (a). Palwothona flavicollis. 
Flavous ; the thorax transverse, impunctate; scutellum black; elytra bright metallic green, closely and finely 
punctured ; the breast and abdomen black. 
Length 1 line. 
Head deeply punctured round the eyes, the middle portion smooth, the frontal elevations broad and distinct, 
the clypeus strongly concave or deflexed ; antennz extending to the middle of the elytra, flavous, the 
fourth joint slightly longer than the third, the following joints scarcely thicker; thorax strongly trans-
