LONGICORNIA. 421 
difference lies in the second pair of round black spots of the elytra being always widely 
distant from each other, and in the presence of a smaller spot on the suture, between 
the first and second pair; so that, viewed from above, the basal half of the elytra is seen 
to bear five black spots in a regular position, thus °° 
Captured in abundance by Mr. Champion on fallen timber in recently burned forest- 
clearings. 
TAPEINA (p. 191). 
Tapeina transversifrons (p. 192). 
To the localities given, add:—Panama, Volcan de Chiriqui, Bugaba (Champion), 
Matachin (Schunke). 
2. Tapeina (?) nudicornis. 
T. transversifronti 2 similis, sed differt :—corpore minus depresso; antennis setis parvis sparsissimis absque 
pilis elongatis, scapo breviori, clavato ; thorace tuberculo laterali mediano acuto, dorso sat dense sub- 
tiliter punctulato; elytris sparsim setifero-punctulatis, marginibus late incumbenti-fusco-pubescentibus, 
setis omnibus brevibus ; pro- et mesosterno multo angustioribus ; pedibus validioribus breviter sparsim 
pubescentibus, tarsis latioribus. 
Long. 23-4 lin. 9? 
Hab. Mexico, Oaxaca, Cerro de Plumas (Hége). 
Three examples, offering no dilatation of the head, and therefore presumably females. 
Although deceptively similar to Tapeina transversifrons, 2, it is doubtful, considering 
the shorter and thicker clavate scape and narrower sterna, whether it can be retained 
in the same genus. The widely-gaping outer rims of the anterior and middle acetabula, 
and the position and form of the conspicuous notch of the middle tibie, do not differ. 
BACTRIOLA (to precede the genus Eumathes, p. 192). 
Gen. Sepiseuthi (Thoms.) proxime affinis. Corpus lineare, tomentosum. Caput inter antennas concavum, 
fronte breviter quadrata, parum convexa, infra haud retracta. Oculi reniformes, lobo inferiori rotundo, 
valde convexo. Antenne corpore paullo longiores, supra versus apices pilose, infra usque ad apices longe 
et regulariter ciliate ; scapo mediocri, gradatim paullo incrassato; articulo 3° quam 4" breviori, 5°-11™ 
decrescentibus. Thorax anguste cylindricus. Elytra supra deplanata, apice rotundata equalia, epipleuris 
verticalibus. Pro- et mesosternum equaliter angusta, plana. Acetabula autica extus triangulariter aperta, 
intermedia paullo aperta. Pedes breves; tibiee intermedi extus medio profunde sinuate; ungues basi 
late dentate, vel “ appendiculate.” 
Allied to the Chilian genus Hebestola, from which it differs inter alia in the unarmed 
thorax, and the middle acetabula distinctly open externally. 
1. Bactriola vittulata. (Tab. XXV. fig. 12.) 
Fusca, obscure cinereo-tomentosa ; thorace vittis quatuor, elytris vitta suturali, altera angusta laterali epipleurisque 
anticis, fusco-nigris ; antennis articulo 4° basi griseo; thorace elytrisque confertim passim punctulatis,
