This is a common and very widely distributed species in the elevated regions of 
Central America, extending northwards into the United States and southwards to 
Costa Rica. MV. levis may be chiefly known by its almost impunctate, dull surface, 
and rather elongate thorax; the elytra in some examples are longitudinally wrinkled’; 
the antenne are simple in both sexes, distinctly thickened towards the tip, and more 
elongate in the male than in the female. A few specimens of the male sex from 
Capulalpam, Peras, and Toluca have the antenne more slender than usual, but Iam 
unable to separate them from WV. levis. MV. cordillerw, Chevr., does not differ in any 
way from MM. levis, Leach, the type of which is contained in the British Museum. 
M. sublevis, Lec., of which I have a male specimen from Colorado before me, merely 
has the elytra more distinctly rugulose than in typical M. levis; several of our 
Mexican examples exhibit this peculiarity, JI have examined upwards of one hundred 
examples, and there can be no doubt that all the above names refer to one and the 
same species. . 
. Antenne long and comparatively slender in both sexes, very little longer in the male, 
not thickened towards the tip. se 
4. Meloe gracilicornis. (Tab. XVII. fig. 4, 2.) 
Entirely black, opaque, smooth (the elytra included), impunctate. Antenne elongate and comparatively 
slender in both sexes, a little longer in the male than in the female, straight, not thickening outwardly 
in either sex, joints 3-7 about equal in length, 8-10 slightly longer, 11 nearly twice as long as 10, of 
equal thickness to beyond the middle and then rapidly narrowing to the apex, its apex somewhat pointed; 
prothorax about as long as broad, narrowing behind, the base rather deeply emarginate in the middle, 
the disc with a smooth central line ; abdomen above and beneath smovth, impunctate; sixth ventral seg- 
ment triangularly emarginate in the male. 
Length 164-36 millim. (¢ 9.)
