form quite an isolated genus. A further difference from Parmena is the rather widely 
open suture of the anterior, and the decidedly open middle, acetabula. 
1. Parmena villosa. 
P. solieri simillima, differt elytris angustius ovatis thoraceque confertissime confluenter punctato. Sat 
angusta, suboblongo-ovata, nigra, undique griseo-erecte pilosa et griseo-incumbenti pubescens; thorace 
sicut in P. soliert; elytris sat confertim equaliter et minus grosse, hic illic sublineatim, punctatis; antennis 
ab articulo 5° basi anguste griseis. 
Long. 4 lin. Two examples. 
Hab. Mexico (Sallé). Named Parmena villosa, Sturm, MS., in the Sallé collection. 
MECYNOME (to precede the genus Moneilema, p. 98). 
Corpus angustissime ovatum, mediocriter convexum, supra parum inzquale. Caput inter antennas concavum ; 
tuberibus antenniferis oblique elevatis, apice obtusis; frons transversim quadrata; oculi infra sat angusti 
obliqui, supra valde distantes. Labrum basi epistomate (sensu Lacordaire) munitum. Antenne corpore 
longiores, sat graciles, filiformes, subtus sparsissime breviter setosze, scapo fere sicut in gen. Lezopo elongato, 
basi intus angustato deinde usque ad apicem cylindrico; articulo 3° gracili, quam scapus longiori; 
4° paullo breviori, ceteris brevioribus gradatim decrescentibus. Thorax subcylindricus, lateribus longe 
post medium tuberculo parvo conico, deinde usque ad basin sinuato-angustatis, Elytra basi thorace 
parum latiora, humeris obtusissimis, deinde usque ultra medium leniter dilatatis, versus apicem citius 
angustatis, apice singulatim subacuminatis. Pedes mediocres; coxe antice salientes; acctabula extus 
clausa; prosterno inter coxas depresso, angusto; mesosternum angustum fere planum; acetabula extus 
clausa; pedes intermedii et posteriores valde approximati; femora gradatim clavata; tibie intermedix 
extus paullo sinuate ; tarsi mediocres, articulo unguiculari sicut in Moneilema lato subdepresso; ventris 
segmentum basale processu semiovato. 
This peculiar form belongs to Lacordaire’s artificial group “ Parmenides.” In general 
form it resembles most the New-Zealand genus Xyloteles, but its real affinity is in the 
direction of Moneilema, or rather of Leptostylus and Idephrynus, of the “ Acantho- 
cinini” group. 
1. Mecynome enescens. (Tab. XXII. fig. 5.) 
Fusco-snea, subnitida, parce setosa et subtiliter ochraceo-fusco incumbente pubescens ; elytris post mediam 
fascia angustissima, a sutura retrorsum versus marginem oblique ducta, canescenti; antennis rufescenti- 
fuscis, articulis basalibus singulis griseo pluriannulatis, apicalibus basi carneo-griseis; thorace grosse 
punctato, dorso trituberculato; elytris confuse punctulatis, utrinque costulis obtusis et parum elevatis 
3 vel 4 seepe interruptis.
