250 HETEROMERA. 
sinuous groove, the surface with a few widely scattered fine shallow punctures ; scutellum smooth ; elytra 
strongly margined, gradually widening to beyond the middle, deeply transversely impressed on each side 
below the base (the base appearing broadly margined), narrowly and finely punctate-striate, the interstices 
flat on the disc, subangularly raised towards the apex and less distinctly so at the sides, smooth ; femora 
cupreous, the tibie metallic green, the tarsi ferruginous suffused above with metallic green ; beneath 
geneous, very shining, almost impunctate, the ventral surface very finely longitudinally wrinkled ; inter- 
coxal process almost rounded in front, margined. 
Length 103- 2 millim.; breadth 5 millim. (¢.) 
Hab. Nicaracua, Chontales (Belt, coll. F. Bates). 
Three examples, apparently all males. 
2. Kpicalla lata. (Tab. XI. fig. 8.) 
Obovate, broad, sneous, very shining. Head finely and sparingly punctured, reddish-ferruginous, suffused 
with sneous; antenne rather short, joint 3 rather more than twice as long as 2, joint 4 shorter 
than but much wider than 3, rather longer than broad, joints 5-10 equal, subtransverse, joint 11 
longer than 10, widening ontwardly, broadly and bluntly rounded at the apex, the eight outer joints 
somewhat flattened, coarsely rugulose, black, the rest ferruginous and smoother ; prothorax transverse, 
strongly margined, the sides straight and slightly widening from the middle to the base, obliquely narrowing 
and slightly rounded before the middle, the anterior angles broadly rounded, the hind angles obtusely 
subrectangular, the basal foves broad and irregular, the surface sparingly punctured, the punctures fine 
but very deeply impressed ; scutellum slightly convex, sparingly punctured ; elytra broad, widening from 
the base to considerably beyond the middle, with regular rows of fine, closely-placed, lightly impressed 
punctures (scarcely striate), which become almost obsolete before the apex, a sharp keel on each side 
(just within the seventh row of punctures) extending a short distance upwards from the apex, the inter- 
stices broad, quite flat (except at the sides) and impunctate, the ninth slightly convex beyond the middle ; 
legs (including the coxee) ferruginous, the outer half of the last joint of all the tarsi abruptly black ; 
beneath seneous, almost smooth, the head, the sterna, and the ventral surface more or less ferruginous, the 
latter very finely longitudinally wrinkled. 
Length 123 millim.; breadth 7 millim. 
Hab. Muxtco (Sailé). One example. 
8. Epicalla cupreo-nitens, (Tab. XI. fig. 9.) 
Obovate, fiery metallic purple, with vivid cyaneous reflections, very shining. Head almost impunctate, purple, 
the anterior half blue; antenne as in Z. lata, but shorter; prothorax very short, strongly transverse, 
narrowing from the base, the sides rounded anteriorly, very strongly margined, the margins deeply grooved 
within, the anterior angles broadly rounded, the hind angles prominent but not acute, the disc with a 
shallow central groove and a transverse impression before the base, the basal fovese deep and extending 
forwards, the surface sparingly, finely, and shallowly punctured, purple, the margins and the basal half more 
or less suffused with vivid cyaneous tints; scutellum longitudinally convex, smooth ; elytra widening to 
considerably beyond the middle, narrowly but deeply striate, the stris finely and shallowly punctured, the 
interstices nearly flat on the basal half, subangularly raised and almost keeled at the apex, smooth, the 
surface of a most vivid fiery cupreous tint without blue reflections, the extreme lateral margins slightly 
tinged with golden ; legs blue; beneath smooth, bluish-purple, the epipleure golden-cupreous, the ventral 
surface finely longitudinally wrinkled. 
Length 10 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
One example. This is one of the most vividly-coloured species of Tenebrionids 
known to me,
