Long. 44 lin. 
Hab. Mexico, Pinos Altos in Chihuahua (Buchan-Hepburn). 
The body is clothed with rather longer and more erect hairs both on the thorax and 
elytra than in LZ. lateralis; the punctuation of the elytra is a little coarser and sparser, 
and has a rough appearance owing to the edges of the punctures being raised. It 
is doubtful if the male above described really belongs to this species: the difference of 
colour of the thorax might not be important, but it differs in outline; the other 
characters are the same, especially the important one of the relative slenderness of the 
antenne ; the elytra, though with similar peculiar punctuation, differ in their truncature, 
which is less obtuse and has a minute projection at its external angle.

E. lateral affinis, sed differt elytris dimidio basali aurantiaco-fulvis. Nigra, capite testaceo-fulvo (partibus 
oris vertice et collo nigris), thoracis lateribus elytrisque dimidio basali aurantiaco-fulvis ; coxis anticis 
tarsisque posticis articulo primo basi testaceis; capite ante oculos sicut in E. laterali angusto sat pro- 
longato; antennis (¢) crassis, basi dense longe hirsutis, articulo 3° quam 4" dimidio longiori; elytris 
creberrime punctulatis, apice late truncatis, angulo exteriori producto acuto.

5. Euryptera sericea. 
Elongata, gracilis, postice gradatim sed modice dilatata, nigra, supra densissime fulvo-aureo incumbenti 
pubescens, sericeo-nitens ; oris vertice vittaque ab occipite per thoracem et suturam usque ad medium 
elytrorum (ibique gradatim angustata) ducta, nigris; capite ante oculos valde angustato sed parum 
prolongato; thorace campanuliformi (post medium leviter constricto); elytris levibus apice oblique 
truncatis ; antennis latis, articulis 3°-4™ brevibus, triangularibus; tarsis posticis articulo 1° valde elongato 
basi pallido.
