TARPELA. 307 
Hab. Mexico, La Parada (Saiié). 
One example. This species may be known by its subparallel and rather convex form ; 
the thorax broad and strongly margined; the elytra with rows of coarse rounded 
impressions and ill-defined metallic green and cupreous stripes (coloured and sculptured 
much as in Helops sumptuosus) ; the stout legs, the tarsi especially stout and with the 
three basal joints dilated in the male, &c. I provisionally include T. crassipes in this 
genus ; it cannot be satisfactorily compared with any of the other species here recorded. 
** Anterior tarsi with the three basal joints narrower, narrowing outwardly and slightly 
or not at all wider in the male.

Hab. Mexico (coll. Chevrolat }2, Sallé, Oberthiir), Jalapa, Matamoros Izucar ({Hége) ; 
Panama, Volcan de Chiriqui (Champion). 
Numerous examples of both sexes of an insect collected by Herr Hage agree fairly 
well with the description of this species. These specimens vary in length from 74-124 
millim. and in breadth from 3-6 millim. The thorax varies in shape, the sides in 
some examples being angulate or crenulate, in others almost rounded; it also varies 
considerably in the intensity of the punctuation—sometimes fine and scattered (as 
. described by Allard), sometimes coarser and closer. 
T. erifera will be known by its bright bronzy colour; the strongly margined thorax, 
the margins a little extended and broadly grooved within ; the elytra long and subparallel, 
with rows of more or less coarse elongate impressions, the interstices flat and distinctly 
punctured. The single example (female) from the State of Panama differs from those 
from Mexico in having the anterior angles of the thorax slightly deflexed ; but I do 
not think it represents more than a variety of 7. wrifera. 
35. Tarpela allardi. (Tab. XIII. fig. 14.) 
Elongate ovate, moderately convex, subparallel, dark bronze, with a slight cupreous or golden tint, slightly 
shining. Head rather long, shallowly transversely impressed in front, closely and moderately coarsely 
punctured; prothorax transversely subquadrate, rather depressed, somewhat broadly expanded at the 
sides, if anything widest before the middle, strongly margined, the margins broadly and shallowly grooved 
within, the sides very feebly crenulate, a little narrowed in front and almost straight behind, the anterior 
angles broadly but not strongly produced and broadly rounded, the apex feebly emarginate, the hind angles 
subrectangular, the base rather feebly bisinuate, the basal foveze small but deep, the disc with a long 
sinuous transverse impression some distance before the base, the surface finely, shallowly, and sparingly 
punctured; elytra comparatively very long, feebly convex, wider than the prothorax, subparallel, the 
humeri a little prominent in front, with rows of rather coarse more or less longitudinal distantly placed 
impressions, the impressions towards the sides and apex deeper and there placed in shallow oblong fovew, 
which are often more or less metallic golden-cupreous within, the interstices flat on the disc, somewhat
