306 HETEROMERA. 
coffee-plantations of the district of El Tumbador, in the department of San Marcos, 
and on the margins of the forest. 
32. Tarpela depressa. (Tab. XIII. fig. 12, ¢ -) 
Oblong ovate, subparallel, depressed, brownish-piceous, with a very slight bronzy tint, shining. Head short, 
shallowly transversely impressed in front, the impression widening out into a deepish fovea on each side, 
rather finely and somewhat sparingly punctured; antenne rather stout, widening a little outwardly, about 
reaching to one third of the length of the elytra (in the male), joints 8-10 subtriangular, the apical joint 
longer than the tenth, dark ferruginous ; prothorax broad, transverse, very strongly margined, the margins 
slightly expanded and narrowly grooved within, the sides a little rounded, narrowing in front, and very 
slightly narrowing and sinuate (almost straight) behind, the anterior angles broadly and rather strongly 
produced and rounded, the apex broadly but not very deeply emarginate, the hind angles subrectangular, 
the base bisinuate and strongly margined, the basal fovese deep, the disc broadly and shallowly trans- 
versely impressed behind, the surface finely, equally, and sparingly punctured ; elytra very little wider 
than the prothorax, strongly margined, subparallel, rather long, the humeri a little prominent in front, 
deeply striate throughout, the stris very finely and shallowly punctured, the interstices feebly convex and 
very minutely and sparingly punctured ; legs dark ferruginous, the tibie rather closely punctured ; beneath 
very sparingly and finely punctured, the flanks of the prothorax almost smooth ; ventral segments 1-3 in 
the male broadly flattened and concave in the middle, the space enclosed exceedingly closely and minutely 
punctured and pubescent ; prosternum smooth, a little declivous, subacuminately and convexly produced, 
the apex armed with a small rounded prominence; mesosternum declivous, moderately excavate. 
Length 84 millim.; breadth 33 millim. (¢.) 
Hab. Mexico, Yucatan (coll. Oberthir). 
One example. This species is remarkable on account of its flattened subparallel 
form; broad, strongly margined, and finely punctured thorax ; deep and finely punctured 
elytral striee ; comparatively smooth under surface ; and male characters. 
The unique example has been kindly lent me by M. Réné Oberthiir ; it is labelled 
“ Helops depressus, Pilate.” 
38. Tarpela crassipes. (Tab. XIII. fig. 13, ¢.) 
Oblong ovate, subparallel, rather convex, dark bronze, with greenish and cupreous tints, moderately shining. 
Head coarsely and moderately closely punctured, the punctures here and there longitudinally confluent, 
the epistoma broadly but feebly emarginate in front and limited behind by a very shallow groove; antennz 
rather stout, comparatively short, piceous ; prothorax broad, transverse, rather convex, the reflexed lateral 
margins prominent and narrowly grooved within, the sides somewhat rounded, slightly narrowing and 
very feebly sinuate behind and more distinctly narrowing in front, the apex somewhat deeply emarginate, 
the anterior angles produced in front and rather broadly rounded, the base strongly bisinuate, the basal 
fovee rather shallow, the disc a little raised anteriorly, the hind angles somewhat obtuse, the surface rather 
coarsely, distantly, and very unequally punctured, the sides and base distinctly suffused with metallic green ; 
elytra moderately long, subparallel, a little flattened on the disc, the humeri rounded but a little prominent 
in front, with rows of coarse rounded rather distantly placed impressions, the impressions still coarser 
and here and there confluent towards the sides, the interstices flat and sparingly but distinctly punctured, 
bronzy-cupreous, each with three ill-defined longitudinal metallic greenish stripes from the base to the 
apex ; legs rather short, stout (the tarsi especially), coarsely punctured ; beneath brownish-piceous, more 
shining, sparingly but rather coarsely punctured, the flanks of the prothorax shallowly strigose ; pro- 
sternum declivous and rounded off behind ; mesosternum broad, declivous, rather deeply excavate. 
Length 73 millim. ; breadth 3$ millim. (¢.)
