segment flavescent, as are also the anal styles, these latter, however, orange-coloured 
at the extremity and much pubescent with black there and at the sides. The male 
has the hind margin of the under plate of the sixth segment very broadly, rather 
deeply emarginate, and the ventral plate of the seventh segment is produced in the 
middle so as to form a very long acuminate process, which is divided to its base by a 
very narrow, elongate slit; the margin of the slit is raised and furnished with a fine, 
not conspicuous, pallid pubescence. 
Only one specimen has been found. 
4, Brachydirus solitarius. 
Gracilis, fulvo-testaceus ; abdomine nigro, apice flavo-testaceo, stylis analibus ad apicem nigricantibus et nigro- 
ciliatis, antennis pedibusque testaceis, femoribus tibiisque posterioribus fuscis; abdomine minus parce 
punctato, segmento 4° transversim albido-pubescente.

Hab. Nicaragua, Fort San Carlos (Sai/é). 
Very similar to B. gracilis, but abundantly distinct by numerous details. Head very 
densely (but not coarsely as in many other species) punctate in front, the punctuation 
on the vertex scanty and obsolete. Thorax coarsely but sparingly punctate. Elytra 
not impressed, rather sparingly punctate. Hind body black, the pale pubescence across 
the fourth segment conspicuous; fifth and sixth segments not sparingly punctate, the 
former with a few white hairs at the side. 
In the male the hind margin of the under plate of the sixth ventral segment is 
broadly emarginate, and the following segment is produced in the middle, and the apex 
of the produced portion bears a short angular notch, the sides of this notch being 
densely pubescent. 
Only one example has been received. 
5. Brachydirus championi. 
Fulvo-testaceus ; abdomine nigro, apice flavo-testaceo, antennis pedibusque testaceis ; elytris parce punctatis, 
abdominis segmentis 3° ad 5™ transversim albido-pubescentibus.

Hab. GuaTEMALA, Zapote, San Isidro 1600 feet (Champion). 
Antenne very short, yellow, joints seven to ten strongly transverse. Head very 
densely punctured, sparingly pubescent. ‘Thorax slightly broader than long, coarsely 
and sparingly punctate. Elytra quite sparingly punctate. Hind body black, with the 
second segment impunctate, bearing some white hairs on its lateral margin; third 
segment sparingly punctate and with scanty white pubescence, fourth and fifth rather 
more closely pubescent; sixth rather sparingly punctate, its hind margin broadly 
yellow ; the following segment and the anal styles also of this colour, but the latter 
fuscescent and nigro-ciliate at the extremity. The male has a small notch at the tip
