552 SUPPLEMENT. 
out, the striz with series of oblong, coarse, deep punctures, which become coarser, deeper, and confluent 
towards the sides, and much finer and shallower towards the suture, the scutellar stria very deep, the 
interstices convex, smooth, the humeri distinct; beneath pitchy-black with an eneous lustre, shining, 
coarsely punctured, the flanks of the prothorax with very deep oblong impressions, the ventral surface 
sparsely, more finely punctate, and finely longitudinally wrinkled ; the first and second segments flattened, 
densely, minutely punctured, and pubescent in the middle in the male ; prosternum narrow, acutely produced 
and slightly declivous behind, the mesosternum V-shaped, moderately raised ; metasternum exceedingly 
short ; intercoxal process triangular, sharply margined ; legs short, pitchy-black with an eneous lustre, 
roughly punctured ; the anterior tarsi with the basal joints moderately dilated in the male. 
Length 4-5, breadth 2-23 millim. (¢ 9.) 
Hab. Mexico, Atoyac in Vera Cruz (Flohr). 
Five examples of this brilliantly-coloured insect have been received. It resembles 
T. eximia in colour, but has more gibbous elytra, much smaller eyes, differently shaped 
antenne, pro-, and mesosterna, &c. In the form of the antenne it approaches Nautes 
antennatus. ‘The species might almost equally well be placed in NMauwtes. This is one 
of many interesting forms for the discovery of which we are indebted to Mr. Julius 
Flohr. 
Tarpela durangoensis (p. 292). 
This species, and 7. corpulenta also, would perhaps be better placed in the genus 
FHlelops. 
8 (a). Tarpela catenulata, (Tab. XXIII. fig. 11, ¢ .) 
Moderately elongate, subparallel, dark brownish bronze, or obscure ferruginous with a brassy lustre; the head 
and prothorax very sparsely clothed with short, appressed hairs, the elytra with one or two rows of widely 
scattered, erect, short, slightly clavate hairs on each interstice. Head coarsely, closely punctate ; antennee 
ferruginous with the tip a little darker, moderately long; prothorax strongly transverse, broadly and very 
deeply emarginate in front, feebly bisinuate at the base, slightly wider at the base than at the apex, the 
sides sinuate towards the base, rounded and converging in front, the lateral margin crenulate towards the 
apex, the anterior angles very strongly and somewhat obliquely produced in front, rather obtuse at the tip, 
the hind angles acutely rectangular, the surface coarsely, closely punctate, very uneven, the basal foves 
deep; elytra moderately elongate, wider than the prothorax, subparallel to beyond the middle, with 
regular rows of coarse, deep, oblong impressions, the impressions closely placed and each impinged upon on 
either side at the middle by a raised point projecting from the interspaces (the impressions thus appearing 
©-shaped), the interspaces each with one or two rows of very widely scattered excessively minute setiferous 
punctures, the third, fifth, and seventh more or less raised, the humeri obtuse ; beneath sneous, shining, 
very coarsely, closely punctate, the flanks of the prothorax very coarsely, longitudinally strigose; pro- 
sternum horizontal, acutely produced, and received by the deeply excavate V-shaped mesosternum, the 
latter vertical in front ; anterior tarsi scarcely dilated in the male. 
Length 43-83 millim. (¢ 2.) 
Hab. Mexico, Temax in North Yucatan (Gaumer). 
Sent in plenty by Mr. Gaumer. Differs from 7. browni, T. thoracica, T. costata, &c., 
by the peculiar sculpture of the elytra; and from 7. browni also by the form of the 
pro- and mesosterna. ‘The elytra bear scattered, serially arranged, subclavate hairs; 
the punctures from which they arise are scarcely visible.
