SCOPAUS. 545 
Four examples were met with of this small insect; they are in very decayed condition. 
The species is like no other known to me. The polished surface, short legs, and 
comparatively broad thorax are diagnostic. 
§ 3. Zarsi longer ; elytra densely punctulate. 
13, Scopzus antoniensis. (Tab. XIV. fic. 6.) 
Fusco-niger ; antennis pedibusque testaceis, illarum basi, horum tibiis geniculisque infuscatis; elytrorum margine 
apicali flavo ; capite latiusculo, posterius rotundato. 
Long. 4 millim. 
Hab. Guatemata, Paso Antonio, Torola (Champion). 
“Antenne rather long, the four or five basal joints infuscate, the basal joint nearly as 
long as the three following together, the third joint not quite so large as the second, the 
penultimate joint about as long as broad. Head convex, the hind angles much rounded, 
the vertex not emarginate ; surface excessively finely, in fact almost invisibly, punctate 
and pubescent, moderately shining.. Thorax ovate, much narrowed behind, punctate 
like the head, with only obsolete traces of a plica at the base in the middle. Elytra 
slender, about as long as the thorax, very finely and densely punctured, dull, their 
punctuation much more distinct than that of the head and thorax. Hind body a 
good deal narrower towards the base. The colour of the under surface is paler, 
fuscous red. The male has a broad not very deep sinuous emargination of the last 
ventral segment, and a very slight emargination of the preceding segment, the more 
basal segments being slightly flattened in the middle of each. A single example was 
found at Torola, and a small series at Paso Antonio. 
14. Scopzeus mollis. 
Rufescens, capite prothoraceque fuscescentibus, elytris nigricantibus margine apicali flavo, antennis pedibusque . 
pallide flavis; capite prothoraceque fere invisibiliter punctulatis, sat nitidis; elytris omnino densissime. 
punctatis, opacis. 
Long. 4 millim. 
Hab. Guatemata, Champerico (Champion). 
This insect is closely allied to S. antoniensis, but in addition to the more pallid colour: 
differs in other details, the most important of which is the extremely dense and even 
punctuation of the elytra, rendering these parts quite dull, and the broader extent of 
the pallid colour at their hind margin. The Amazonian S. ornatus, Sharp, is extremely 
close to this, but is a broader insect with more rounded sides to the thorax. Only two. 
examples were procured, and they are both females. 
15. Scopseus carissimus. 
‘Niger, tibiis tarsisque testaceis, antennis fusco-rufis ; sat nitidus, elytris omnino peropacis, margine apicali 
flavo. 
Long. 3$ millim.
