17. Leptostylus levicauda. 
LZ. oblongo-ovatus, cinereo-fuscus, elytris cinereis macula mediano-laterali magna atro-fusca, declivitate 
posteriore sericeo-fusca levi, hoc colore angulum acutum antice ad suturam formante; thorace tube- 
ribus dorsalibus vix elevatis, lateralibus fere obsoletis ; elytris postice modice angustatis, apice oblique 
et obtuse truncatis, dorso penicillis‘prope basin altis acutis, ceteris parvis; epipleuris fere verticalibus 
carinulaque delimitatis ; antennis carneo-griseis, articulis apice fuscis, 1°-6™ fusco guttatis ; pedibus cinereo- 
hirsutis, tibiis apice tarsisque nigris.

This species recedes a little from the numerous group of which L. transversus is the 
type, in the weaker development of the thoracic tubercles and the less hispid surface of 
the elytra. In the latter the apical declivity is smooth and silky, the colour being 
limited anteriorly very obliquely, extending in an acute angle up the suture. 
18. Leptostylus obliquatus. 
L. oblongo-ovatus, cinereo-fuscus, elytris fascia angusta postica valde obliqua cinerea maculaque mediano- 
laterali fusca; thorace tuberibus dorsalibus duobus anterioribus elevatis, ceteris minus distinctis, late- 
ralibus prominulis et postea margine sinuato-angustato ; elytris minus inzequalibus, parum convexis, prope 
apicem modice angustatis, apice fere rotundatis, dorso penicillis parvis vix hispidis, punctulatis ; epipleuris 
subverticalibus ; antennis griseis, articulis apice anguste fuscis, 3° et 4° fusco guttatis; sternis sic ut in 
L. transverso latis.

Hab. Mexico, Oaxaca (Boucard?), Juquila (Sadlé). 
A species closely allied to L. dewvicauda, both being members of a small group which 
differ from Z. transversus in the much smoother and more even surface both of thorax
