Mastax læviceps n. sp. 
Mastax pulchello (Dej.) affinissimus et similis sed differt inter 
alia capite et thorace lævibus politis elytrisque postice absque 
puncto albo suturali. Parvus, testaceo-rufus, abdomine, antennis 
(articulis 1-3 exceptis), femoribus tibiisque 4 posticis et tarsis apice 
fuscis, capite supra plus minusve nigro-æneo, elytris nigro-fuscis, 
viridi-tinctis, sericeo-opacis, utrinque basi fascia arcuata interrupta 
testacea, postice macula rotunda laterali argenteo-alba. Caput læve, 
politum, juxta oculos acute bistriatum, inter antennas sulco utrinque 
laterali frontali. Thorax basi et apice subtiliter rugulosus, medio 
toto lævis politus, spatio parallelo inter lineas dorsales lævis- 
simo. Elytra costis obtusis subnitidis utrinque quatuor, costis 
suturali et secunda inter se costulis transversis 4-5 connexis. — 
Long. 21/4 millim.

The short transverse costulæ connecting the sutural and second 
costæ of the elÿtra and giving an alveolated appearance to the 
broad first interstice, is mentioned by Chaudoir as a character of his 
M. strialiceps, the costulæ appear however, to be far less 
pronounced in that species than in 7. lvviceps. 
Subfamily ORTHOGONIIN Æ. 
Orthogonius lucidus n. sp. 
O. fugax (Chaud.) affinis, antennis capite cum thorace multo 
longioribus. Niger nitidus, elytris præcipue politissimis, femoribus 
flavo-testaceis, tarsis, antennis et palpis rufo-piceis (antennis arti- 
culis 1-2 palpisque interdum clarius rufis). Caput fortiter intricato- 
rugosum, fronte anteriori cum epistomate plus minusve lævi; 
sutura frontali profunda utrinque abbreviata et in foveam desinenti. 
Thorax fere sicut in O. puncticolli et affinibus lateribus rotundatis, 
antice multo magis quam postice angustatus, angulis posticis paullo 
obtusis sed valde distinctis; margine laterali sat late, postice latius, 
explanato et fortiter reflexo, nullo modo rufescenti, grosse trans- 
versim rugoso, disco ruguloso. Elytra oblonga, apice obtuse truncata, 
apice suturali oblique et obtuse abscisso; punctulato-striata, inter- 
stitiis 2-7 subæqualibus, paullo convexis, postice suturam versus 
planissimis ibique striis vix impressis, 3i° 5t° et 7% punctis parvis 
paucis, 3° grosse tripunctato. Prosternum variat : acute margina- 
tum, indistincte marginatum, immarginatum. Tarsi omnes art. 4!° 
bilobato, ungues pectinati. — Variat, ©. nitidulus : femoribus
