614 CRYPTOPHAGID&. 
thorace fortiter transverso, linea marginali anteriore discreta, dorso subtilius punctato; elytris versus 
suturam seriebus punctorum omnino obsoletis. 
Long. 33 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 4000 feet (Champion). 
In the male of this species there is a short longitudinal carina on the middle of the 
front of the epistome, and on the vertex above this a shallow depression; over the 
imsertion of each antenna there is a strongly raised, rather short carina directed out- 
wards and backwards, and there are a few punctures between these structures; the 
marginal line has two minute granules on the middle. In the female the carine are 
absent. G. subtilis is distinguished from all the following species, G. chontalenus 
excepted, by the fact that, when viewed from above and behind, the anterior marginal 
line can be distinctly traced along all the middle of the thorax. The species may be 
known by the punctuation near the suture of the elytra being more than usually 
obsolete, and the punctuation on the disc of the thorax scanty and fine. 
I have treated as a variety three specimens from Bugaba in which the punctuation 
of the thorax and the sutural portion of the elytra is distinctly coarser. The male 
characters do not, however, differ from those of the other examples. 
22. Gonicelus chontalenus, sp. n. 
Suboblongus, parum elongatus, haud depressus, rufescens, longius pubescens ; prothorace haud fortiter 
transverso, linea marginali anteriore sat discreta; elytris punctis versus basin sat magnis, versus apicem 
obsoletis. 
Long. 3 millim. 
Hab. Nicaragua, Chontales (Janson). 
An obscure species, but apparently to be distinguished from the others it resembles 
by the anterior marginal line of the thorax being visible in the middle. The thorax is 
but little narrowed in front; the punctuation on the disc is rather fine and not dense ; 
the anterior marginal line is deflexed near each side and is more prolonged backwards 
than usual in the small species of the genus, indeed from one point of view it appears 
to reach the base. The series of punctures on the elytra are very distinct at the base 
and the punctures large ; but the sutural series is quite indistinct. 
Tam uncertain as to the sex of the unique individual. The surface of the head is a 
little uneven, and there is an obscure depression on the vertex, and a very slight 
angulation of the front margin of the thorax in the middle. 
23. Gonicelus planus, sp. n. 
Oblongus, angustus, subdepressus, rufus, pubescens ; prothorace transversim subquadrato, dorso crebre fortiter 
punctato, versus latera parum sculpturato ; elytris seriatim punctatis, 
Long. 24 millim. 
Hab. Panama, Bugaba (Champion).
