612 CRYPTOPHAGIDZ. 
This is easily distinguished from all the other species of Gonicelus, G. securiger 
excepted, by the long pallid pubescence of the upper surface, which is conspicuous even 
on the head and thorax. The head is small, the antenne long. ‘The thorax is short, 
and at the base is slightly narrower than the elytra; the hind angles are rectangular ; 
the marginal line is distinct in the middle in front; the basal margin is dilated in 
front of the scutellum ; the few coarse punctures at the sides behind are not separated 
by depressions or elevations. ‘The last joint of the labial palpus is very large, but not 
securiform. The flanks of the thorax have no large punctures. The prosternal process 
is narrow and much bent upwards. 
‘Two specimens; the head is quite destitute of elevations and the, front tibie are 
simple: they may both be females. 
17. Gonicelus securiger, sp. n. 
Ovalis, parum convexus, piceus, pube pallidiore elongata vestitus ; antennis pcdibusque rufis ; prothorace 
minore, elytris paullo angustiore ;, elytris seriebus punctorum internis obsoletis. 
Long. 5 millim. 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
Very similar to G. vestitus, but with numerous distinctive characters, and very 
remarkable by the excessive development of the last joint of the labial palpi, which is 
extremely broad and securiform. ‘Thoracic marginal line subobsolete in front. Antenne 
unusually long and slender, the club loosely articulated. 
Two specimens: they bear no indication of their sex. 
18. Gonicelus hystrix, sp. n. 
Anguste ovalis, parum convexus, niger, pube elongata erecta concolore vestitus ; antennis pedibusque rufis vel 
piceis ; prothorace elytris fere angustiore, dorso irregulariter fortiter punctato ; elytris seriebus internis 
punctorum minus obsoletis. 
151 milli 
Long. 43-54 millim. 
Hab. Mexico, Jalapa (Hége), Cordova (Sallé). 
This species is distinguished from all the preceding by the numerous coarse punctures 
on the under surface of the body, and by their especially large development on the 
flanks of the thorax ; it is also remarkable by the straight, upright, setiform pubescence. 
The antenne are moderately long. The head is coarsely punctate, without any 
tubercles. ‘he thorax is small, the front angles very little produced, the marginal 
line very distinct in the middle in front, the hind angles rectangular, the basal margin 
not dilated in front of the scutellum; the coarse lateral punctuation is extensive, and 
there is much rather coarse punctuation on the middle. Prosternal process narrow, 
much bent upwards. 
Eleven specimens; there is a slight emargination of the front tibia, but I do not 
find any sexual distinctions. |
