TARPELA. 305 
rather coarse scattered impressions, the ventral segments 1-3 in the male finely and closely punctured and 
pubescent along the middle; prosternum rather narrow, slightly grooved between the cox, declivous, the 
apex scarcely raised. 
Length 5-7 millim.; breadth 24-3 millim. (¢ 9.) 
Hab. Guaremata, El Jicaro, Tocoy, Rio Maria Linda (Champion). 
Seven examples. A small metallic bluish-green species somewhat resembling the 
Cuban Nautes rufipes, All., but much smaller and with differently-formed head, 
prosternum, &c. From Helops mutabilis, Waterh., from Jamaica, which it resembles 
in size and colour, it will be known by the head being more convex and not nearly so 
distinctly impressed in front, the less prominent anterior angles of the thorax, the more 
finely punctured elytral strie, &c. 
31. Tarpela subvittata. (Tab. XIII. fig. 11 ¢.) 
Oblong ovate, subparallel, moderately convex, bright bronze, with greenish and cupreous reflections, shining. 
Head transversely impressed in front, the epistoma broadly and shallowly emarginate, coarsely and closely 
punctured, the punctures a little more crowded in the centre of the intraocular space and here and there 
obliquely or longitudinally confluent ; antennz moderately long, reaching to about one third of the length 
of the elytra in the male, joints 8-10 narrow, piceous; prothorax transverse, rather convex, strongly 
margined, the margins grooved within, the sides rounded about the middle, feebly sinuate and scarcely 
narrowing behind, and obliquely narrowing in front, the anterior angles broadly but not very strongly 
produced and broadly rounded, the hind angles subrectangular, the base feebly bisinuate and strongly 
margined, the basal foveee moderately deep, the disc transversely flattened before the base, the surface 
closely, moderately coarsely, and subequally punctured, a narrow ill-defined longitudinal space on 
the basal half of the disc impunctate ; scutellum large, subtriangular; elytra long, wider than the pro- 
thorax, subparallel, the humeri a little prominent in front, narrowly and regularly striate throughout, 
the strie finely and somewhat distantly punctured on the disc, a little more coarsely so towards the 
sides, the interstices flat on the disc, feebly convex outwardly, and very distinctly, somewhat closely, 
and comparatively not very finely punctured, the sutural and marginal interspaces and a broad ill-defined 
oblique stripe from the shoulder (chiefly confined to the third, fourth, and fifth interspaces) to the apex 
more or less tinged with metallic green ; beneath shining, dark bronze, the sides and the last two ventral 
segments with bluish reflections, sparingly punctured, the ventral segments 1-3 also coarsely longitudin- 
ally wrinkled and in the male with a very closely punctured pubescent space along the middle, the 
metasternum with scattered coarse impressions at the sides; legs dark bronze, the tibie coarsely and 
roughly punctured ; prosternum slightly declivous, strongly acuminately produced, the apex a little raised ; 
mesosternum declivous, broad, moderately deeply excavate. 
Length 9-10: millim.; breadth 32-42 millim. (¢ 2.) 
Hab. Guatemaa, El Tumbador 2500 feet (Champion). 
Two examples. This insect somewhat resembles 7. cupreo-viridis, but is readily 
distinguished by the punctate-striate elytra and very distinctly punctured interstices, 
and also by the rougher tibiz and the differently formed pro- and mesosterna; from 
T. puncticeps it is separated by its larger size, longer and more parallel elytra, more 
distinctly punctured interstices, rougher tibie, shorter antenne, more coarsely punc- 
tured metasternum, and other characters. 
T. subvittata is one of several allied species found by myself in the same locality on 
the Guatemalan Pacific slope. These insects were all captured in the vicinity of the 
BIOL. CENTR.-AMER., Coleopt., Vol. IV. Pt. 1, August 1887. ORR
