CONOTRACHELUS. 405 
much narrowed in front, feebly bisinuate at the base; rather coarsely, rugosely punctate, obsoletely 
carinate anteriorly. Elytra broad, subtriangular, rounded at the sides posteriorly, slightly dilated beneath 
the humeri; punctate-striate, the interstices densely rugulose, 3, 5, 7,and 9 very sharply, uninterruptedly 
costate, 10 also with an acute ridge at the base. Intermediate coxe distant, the mesosternum flattened. 
Ventral segments sparsely punctate. Legs rugose; femora unidentate ; tarsal claws with a short, fine 
tooth. 
Length 4, breadth 24 millim. (3?) 
Hab. Guatemaa, San Juan in Vera Paz (Champion). 
One specimen. A short, broad ovate form, with a very stout, strongly arcuate 
rostrum, a rugosely punctate prothorax, and subtriangular elytra, the latter with a very 
conspicuous white spot on each shoulder and another near the suture beyond the 
middle, and the alternate interstices sharply costate throughout. 
116. Conotrachelus scoparius, sp.n. (Tab. XX. figg. 18,18 a, ¢; 186, hind 
leg, 3.) 
Oblong-ovate, dull, piceous, the elytra obscure ferruginous with darker markings, the antenne, and the legs 
in great part, ferruginous; the vestiture fine, close on the head and elytra, and sparse elsewhere, fulvous, 
the elytra faintly mottled with whitish, the third and sixth interstices each with a dense fulvous spot at 
the base, the femora incompletely annulate with fulvous, the anterior pair with a fulvous line at the base 
above, the upper surface and legs also with scattered fine semierect setee. Head densely punctate, feebly 
foveate and a little depressed between the eyes; rostrum stout, curved, about as long as the head and 
prothorax, rugulosely punctate and feebly 5-carinate, the antennz inserted near the tip, joints 1 and 2 
of the funiculus subequal in length, 4-7 transverse. Prothorax transverse, rounded at the sides 
anteriorly, constricted and narrowed in front, strongly bisinuate at the base ; densely, rugulosely punctate, 
carinate to the base, the narrow interspaces obsoletely granulate. Elytra oblong, subparallel in their 
basal third, sinuate in front, the humeri rounded ; coarsely and shallowly seriate-punctate, the interstices 
densely rugulose, 3, 5, 7, and 9 finely costate throughout. Ventral segments densely, coarsely punctate. 
Mesosternum flattened between the cox, protuberant and bituberculate in front. Metasternum broadly 
depressed and pilose in the middle. Fifth ventral segment foveate at the apex. Femora clavate, 
unidentate. Tibie each with a long brush of fulvous hairs at the apex, the usual hook almost obsolete. 
Tarsi clothed with long hairs at the base beneath, the claws with a moderately long slender tooth. 
Length 5, breadth 2} millim. (<d.) 
Hab. Mexico, Yautepec in Morelos (Hége). 
One specimen. Differs from all the species here enumerated in the peculiar male- 
characters, the tibie, tarsi, and metasternum each showing a sexual mark of distinction. 
It approaches C. posticatus (Say). 
117. Conotrachelus lobatus, sp.n. (Tab. XX. figg. 19, 19 a, ¢ ; 194, front 
leg, ¢; 19¢, hind leg, ¢.) 
Oblong-ovate, feebly shining, nigro-piceous, more or less mottled with ferruginous, the elytra sometimes in 
great part ferruginous ; the vestiture very sparse, ochreous, closer and somewhat fasciculate on the 
elytra, the latter with a small spot at the base of each of the third and sixth interstices, the femora 
obsoletely annulate at the middle, the upper surface and legs also with short, fine, scattered, semierect 
sete, those on the elytra seriately arranged down each interstice. Head densely punctate, foveate 
between the eyes; rostrum inthe ¢ moderately stout, curved, a little longer than the head and prothorax, 
rugulosely punctate, and 5-carinate almost to the tip, in the 2 with the carinw less extended and the
