than long, feebly bisinuate at the base, a little rounded at, the sides, the hind angles rectangular; beneath 
in great part piceous ; legs slender, entirely testaceous. 
Length 23° millim. 
Hab. Guatemata, Capetillo (Champion). 
One example. Less elongate than P. guadriguttata, the antenne a little shorter, the 
thorax and elytra testaceous, the latter with a median black fascia divided at the suture. 
The elytra are, relatively, a good deal shorter than in the above-mentioned species. 
P. nubila, Lec., from California, is evidently an ally of P. unifasciata; but, according 
to J. B. Smith’s figure (Trans. Am. Ent. Soc. x. t. 1. fig. 11), it is a more elongate insect, 
and has the elytral fascia uninterrupted at the suture. 
9. Pentaria decolor. 
Moderately elongate; testaceous, the elytra sometimes slightly infuscate along the middle of the dise and having 
the suture and sides paler, the prothorax more ferruginous in colour in some examples; the upper surfaee 
opaque, thickly clothed with fine silky pubescence, the prothorax and elytra finely transversely strigose. 
Head moderately large, the eyes black; antenne rather short, thickening outwardly, joints 9 and 10 
subtransverse, testaceous, the apical joints sometimes infuscate; palpi testaceous; prothorax about one 
half broader than long, feebly bisinuate at the base, moderately rounded at the sides, the hind angles 
rectangular; beneath varying in colour from testaceous to fuscous; legs entirely testaceous; sixth ventral 
segment partly exposed in the male, and sometimes visible in the female. 
Length 2-3 millim. (¢ 2.) 
This species appears to be common in Mexico, whence we have received a large 
number of specimens. Those forwarded by Morrison from Sonora were labelled 
Anaspis rufa; the present insect, however, differs from Anaspis in having a well- 
developed bilobed penultimate joint to the anterior and middle tarsi. The entirely 
pale colour and the less elongate shape distinguish it at once from P. quadriguttata, 
and the larger size, longer antenne, and immaculate elytra separate it from P. unifas- 
ciata; P. decolor is, however, not very closely allied to any of the other species here 
described, though P. angustata comes near it. 
10. Pentaria angustata. 
Moderately elongate, narrow, testaceous; the upper surface opaque, finely pubescent, the prothorax and elytra 
very finely transversely strigose. Head moderately large, the eyes black ; antennz rather short, thickening 
outwardly, joints 9 and 10 transverse, testaceous, the apical four joints a little darker; prothorax about 
one half broader than long, narrowing from the base, the sides very little rounded, the hind angles rectan- 
gular; beneath and the legs testaceous. 
Length 12 millim. (¢.) 
Hab. Nicaragua, Chontales (Janson). 
One male example. Narrower and smaller than P. decolor, the antenne shorter, the. 
thorax less rounded at the sides. The transversely strigose elytra and the longer and
