160. Conotrachelus scapularis. (Tab. XXI. figg. 16, 16a, ¢.) 
Conotrachelus scapularis, Fahy. in Schénh. Gen. Cure. iv. p. 419 (nec Chevr.*) *. . 
Hab. Mexico, Alvarado in Vera Cruz (Chevrolat 1), Jalapa (Hége) ; British Honpuras, 
Rio Hondo (Blancaneaux); GuateMaLA, Zapote (Champion). 
_ We have ten specimens of this species, some of them agreeing well with the type. 
In fresh examples the prothorax has an oblique, sinuous, white or whitish line on each 
side of the disc, the two lines more or less connected at the middle and towards the 
apex, sometimes sending off a short longitudinal branch at the base, and continued 
posteriorly along the front of the humeri; the elytra have also a few very small, 
scattered, white spots on the disc. The rostrum is rugulose and carinate in the male, 
smoother in the female. The prothorax is carinate at the middle. The elytra are 
short, broad, subtriangular, with the alternate interstices moderately costate, the first 
and second ridges depressed or interrupted below the base. The mesosternum and the 
front of the metasternum are slightly hollowed in the middle. The first two ventral 
segments are coarsely, the others minutely punctate. The femora are unidentate at 
the middle. The tarsal claws have a short tooth. 
161. Conotrachelus aristatus, sp.n. (Tab. XXI. fige. 17, 17a, 2.) 
Subovate, black, the rostrum, antenne, and tarsi more or less ferruginous; densely clothed with oval, 
reddish-brown scales, a few whitish ones being intermixed on the head, prothorax, and humeri, the 
vestiture of the under surface sparse, the upper surface also with scattered whitish and fuscous sete, the 
latter clubbed and clustered into fascicles on the dorsal prominences of both the prothorax and elytra, 
the legs with whitish setz, the femora biannulate. Head densely punctate, transversely depressed above 
the eyes ; rostrum stout, curved, about as long as the head and prothorax, rugulose and feebly tricarinate 
to near the middle and smooth and shining thence to the apex, the antennx inserted at some distance 
before the tip, joint 2 of the funiculus shorter than 1. Prothorax convex, broader than long, narrowed and 
constricted in front, the sides parallel behind, the base moderately bisinuate; densely, rugulosely punctate, 
the disc abruptly gibbous at about the middle and feebly binodose at the apex. Elytra subtriangular, with 
the humeri abruptly, obliquely truncate in front and angularly dilated at the sides ; seriate-punctate, the 
interstices rugulose, 3, 5, 7, and 9 sharply costate, the ridge on 3 and 5 very broadly twice interrupted, 
the others flat. Meso- and metasternum slightly depressed between the middle cox, the mesosternum 
nodose on each side in front. Ventral segments sparsely, finely punctate. Legs stout; femora strongly 
_ clavate and acutely unidentate ; tarsal claws with a short tooth. 
length 5, breadth 23 millim. ( 2.) 
_ Hab. GuateMALa, Panima in Vera Paz (Champion). 
One specimen. Near C.-hwmerosus, Fahr., but separable therefrom by the coarsely 
fusco-setose dorsal prominences of the prothorax f and elytra, the oval scales of the 
upper surface, and the mesially depressed metasternum.
