2. Choriolaus latescens. (Tab. XX. fig. 9.) 
Facies gen. Lyci, elytris latis oblongis apice late truncatis, angulo suturali nullo, exteriori acuto. Niger, thorace 
(supra et infra), elytrorum dimidio basali et femoribus aurantiaco-fulvis ; dense breviter suberecte pilosus ; 
capite ante oculos brevi sed angusto; antennarum articulis 8°-5™ linearibus subzqualibus ; thorace sat 
graciliter campanuliformi; elytris equaliter convexis, crebre punctulatis, 
Long. 53 lin. 9. 
Hab. Mexico, Oaxaca (Sallé). 
One example only. At first sight this species would be taken for a Euryptera, the 
general form being that of EH. latipennis; but the filiform third and fourth joints of 
the antenne and the long hind tarsi effectively separate it generically from Huryptera. 
8. Choriolaus nanus. (Tab. XX. fig. 8.) 
Minutus, oblongus, dense breviter pilosus, fulvo-testaceus ; antennis, elytris, tibiis, tarsis femorumque apicibus 
chalybeo-nigris; capite ante oculos brevissimo et lato; antennis filiformibus versus apicem haud incras- 
satis, 3° modice elongato, 4° dimidio breviori; thorace late campanuliformi, mox ab apice dilatato, deinde 
usque ad basin subrecto latitudine elytris «quali; elytris equaliter convexis, apice singulatim rotundatis, 
minus crebre punctulatis. 
Long. 22 lin. 9. 
Hab. Mexico (Sallé). 
One example. ‘This species bears a strong superficial resemblance to a species of 
Mordellistena (i.e. M. abdominalis, 3, of Europe). 
EURYPTERA (to precede the genus Chontalia, p. 40). 
Euryptera, Serville, Encycl. Méth. x. p. 688 (1825) ; Ann. Soc. Ent. Fr. 1835, p. 22. 
An exclusively American genus, chiefly belonging to the tropical zone, but having at 
least one representative in North America. Lacordaire infelicitously modified the 
characters given by Serville (which rely chiefly on the form of the antennal joints and 
define a fairly natural genus), and I purposely abstain from citing his description in 
the ‘Genera des Coléoptéres.’ Seven species, so far, have been described. 
1. Euryptera lateralis. 
Leptura lateralis, Oliv. Ent. no. 73, p. 22, t. 3. f. 37. 
Euryptera lateralis, Crotch, Check-list Col. N. Amer. p. 90. 
Leptura distans, Germ. Ins. Sp. Nov. p. 524°. 
Hab. Norta America !.—MeExico, Oaxaca, Playa Vicente (Sallé). 
2. Kuryptera costulata. 
E. laterah affinis et similis; differt elytris utrinque bicostatis apiceque singulatim rotundatis. Gracilior, 
nigra, opaca ; occipite, thoracis lateribus margineque humerali elytrorum, fulvo-aureis; capite ante oculos 
toto nigro; elytris multo minus crebre punctulatis, humeris (supra visis) nigris, costis dorsalibus elongatis 
duabus epipleurisque abrupte verticalibus; femoribus anticis basi tarsisque 4 posticis articulo 1° basi 
flavo-testaceis.
