4, Obrium angulosum. (Tab. XIX. fig. 7.) 
‘O. liturato affine et simile; differt litura elytrorum apicali utrinque angulata (sicut circumflexum), angulo 
versus basin spectante et maculas fuscas postico-discoidales attingente. Pallide testaceum, nitidum, 
setosum ; thorace (mox a sulco apicali late rotundato-dilatato), vittis duabus, elytris utrinque lituris quinque, 
 fuscis (lituris 1° et 2° sicut in O. liturato parallelis obliquis retrorsum versus suturam, 3* et 4» post 
medium discoidalibus breviter vittiformibus, interiori suture subparallela, 5° angulata ab apice sat 
remota); antennis articulis apice fuscis. 
Long. 34 lin, 
Hab. Panama, Tolé (Champion). 
Very closely allied to O. lituratum, but differing in the form of the thorax, which is 
more broadly cordate than in O. cordicolle; in markings it agrees with O. lituratum in 
the two slender subbasal fascie of the elytra being nearly parallel and oblique rear- 
wards from the base to the suture; the posterior discoidal patch is, however, much 
shorter and divided into two short subparallel vitte, and the subapical fascia, instead of 
being near the apex and straight or slightly oblique, is further removed from the apex 
and on each elytron angulated in the middle, with the angle directed towards the base 
and touching the discoidal streak.

Hab. Panama, Bugaba (Champion).—SoutH America, Amazons !. 
Also closely allied to O. pallidum and O. lituratum. The thorax is dilated and rounded 
from the anterior sulcus, but much less so than in 0. angulosum. In markings it differs 
from the allied species in the form and position of the posterior fuscous markings of 
the elytra, which here consist of two slender fascie curved in such manner that the two 
together form on the elytra a common large transverse-oval ring. The original de- 
scription was drawn up from a single specimen, evidently immature or defective in 
colouring, the antenne and thorax being spotless or nearly so, and the basal markings 
of the elytra indistinct; the antennal joints in well-developed individuals, of which 
Mr. Champion took a good series, are tipped with fuscous, the thorax has two fuscous 
vittee, and the base of the elytra a broad fascia, from the hinder edge of which proceeds 
on each elytron an oblique streak extending to the suture, of the same chestnut-brown 
colour. ‘The hind femora and tibie are also more or less streaked with fuscous. | 
6. Obrium piperitum. (Tab. XIX. fig. 12.) 
0. pallido affine; gracile, pallide testaceum, nitidum ; elytris punctis setiferis seriatis fuscis, fasciisque angustis 
utrinque quatuor, 1* subbasali intus versus scutellum curvata, 2a paullo posteriori abbreviata recta, 
3* post medium vix arcuata apud suturam postice continuata, 4* valde retrorsum (versus suturam) obliqua 
prope apicem ; antennis articulis apice, femoribus 4 posticis (plus minusve) tibiisque apice, fuscis; thorace 
angusto, subelongato, mox pone sulcum anteriorem subito, sed modice rotundato-dilatato deinde ad basin 
gradatim angustato, dorso ineequali setifero-punctato. 
Long. 23-33 lin.
