and slightly reflexed, and with a short erect tubercle in the middle ; prothorax strongly transverse, convex, 
the sides feebly margined, smooth, the disc usually with a distinct fovea on each side before the middle ; 
elytra with rows of rather coarse rounded impressions, the impressions finer towards the suture, the inter- 
stices smooth ; anterior tibiz in the male curved, with a short triangular tooth on the inner side near the 
middle, and a short blunt tooth .at apex ; intermediate and posterior tibie in the male slightly swollen a little 
before the middle ; prosternum smooth, horizontal, the apex strongly produced and rounded; mesosternum 
raised obliquely on each side anteriorly, deeply excavated within ; ventral segments longitudinally wrinkled. 
Length 15-192 millim. (¢ 2.)

F. Bates).—Coutomsia; Brazit. 
3. Nuptis inquinatus. (Tab. V. fig. 21, ¢.) 
Black, shining. Head irregularly, shallowly, and somewhat coarsely punctured, flattened and impressed and 
rugulose between the eyes ; epistoma in the male concave within, the anterior margin raised and slightly 
reflexed, and with a short erect tubercle in the middle ; prothorax transverse, widest about the middle, 
the sides rounded and very narrowly margined, strongly convex, with an indistinct central line, the disc 
feebly impressed transversely before the base, shallowly, finely, and sparingly punctured ; elytra indistinctly 
striate, with rows of moderately coarse (or coarse) longish or rounded impressions, the impressions finer 
towards the suture, interstices smooth and almost impunctate ; anterior tibie curved, in the male with a 
short triangular tooth on the inner side near the middle; prosternum subhorizontal, slightly deflexed, 
the apex produced and broadly rounded ; mesosternum slightly concave in the middle in front. 
Length 17-20 millim. (¢ 92.) 
Hab. GuateMALa, El Reposo, Pantaleon, Zapote, El Tumbador, San Juan in Vera 
Paz (Champion). 
Rather common in Guatemala. 
4. Nuptis caliginosus. (Tab. V. fig. 20, 3.) 
Black, shining. Head shallowly, irregularly, and rather finely punctured, flattened and excavated and rugulose 
between the eyes ; epistoma in the male concave within, the anterior margin raised and slightly reflexed, and 
with a short erect tubercle in the middle ; prothorax strongly convex, transverse, widest about the middle, 
the sides rounded and very narrowly margined (the lateral margins scarcely visible from above), the base 
strongly margined, smooth, and almost impunctate, the disc sometimes with a rounded impression on each 
side before the middle ; elytra with rows of deep, coarse impressions, the impressions scarcely finer towards 
the suture, obsoletely striate, the interstices almost smooth ; anterior femora in the male toothed beneath ; 
anterior tibiz in the male with two short teeth (one sharp and triangular near the middle, midway between 
which and the apex there is another and blunter tooth), in the female slightly swollen in the middle ; 
posterior tibie in the male slightly swollen (or obsoletely toothed) a little before the middle ; tarsi densely 
clothed with fine long fulvous hair beneath; prosternum deflexed behind, slightly produced, the apex 
broadly rounded and slightly embracing the coxe. 
Length 17-19 millim. (¢ 2.) 
Hab. Muxico (coll. F. Bates), Cordova (Sallé), Jalapa (Hége). 
Seven examples. The male of this species may be known at once from its allies by 
the toothed anterior femora and the armature of the anterior tibie; the female by the 
anterior tibie slightly swollen (or bluntly toothed) in the middle. In some specimens, as 
in the allied species, the elytra are more finely punctured than in others.
