pubescentia, ultimo pilis paucis longiovibus erectis vestito. 
Long. circa 7 mm. 
The pronotal band at its widest hardly reaches the middle of 
the length of the pronotum; the second abdominal segment is 
thinly clothed with more or less erect hairs, its apical fascia 
is not dilated at the sides, and only moderately wide, not 
occupying more than about one-fifth of the segment.

3. Niger; clypeus maculaque interantennalis elongata auran- 
tiaco-flavescentes. Pronoti macule due, et tegule ex majore 
parte, rufescentes. Segmentum abdominis primum et secundum 
postice rufo-marginata, fascia prima latera versus angustata, 
secunda utrinque valde dilatata, ibique ante aut ad medium 
segmenti longitudinem extensa, ceteris segmentis (saltem ex 
majore parte) rufis aut aurantiacis. Tibiz tarsique rufescentes. 
Species minor, sed haud gracilis. Clypeus lunulato-emarginatus, 
ex majore parte subdeplanatus, distincte, remote, haud grosse 
punctatus, basi lateribusque suis argenteo-pubescens. Frons 
cum thorace crebre pilosa. Mesonotum dense punctatum, 
scutello inermi. Tegule grosse et conspicue punctate. Ab- 
dominis segmentum secundum dorsale dense, grossius punctatum, 
parte basali fortiter convexa; ventrale, post sulcum, fortiter 
abrupte elevatum, et postice grosse denseque punctatum., Anguli 
posteriores segmenti 2 dorsalis conspicue acute producti. Long. 
circiter 8 mm.

Exactly like the preceding in general appearance, but the 
elypeus is distinctly less produced apically and less flattened, and 
its puncturation rather coarser. The lateral angles of the hind 
margin are only very slightly produced backwards. The wings 
are hardly infuscate, except along the costa, where the infuscation 
is dark and conspicuous. In the preceding species the wings are 
folded and appear dark, but this may be only due to the folding. 
Both species have a small postocular spot on each side of the head, 
which was not mentioned in my description of the preceding, 
In both, the apical antennal joints are excessively minute, 
forming a sort of small tubercle in the concavity of the eighth, and 
it is ditticult to tell whether two or three joints are here present, 
but I have satisfied myself that there are three, so that the 
antenne are normal for the genus, 11-jointed.
