618 CRYPTOPHAGIDA. 
between the species with well-marked anterior marginal thoracic line and those 
without. There is on the thorax a fine intra-lateral line which is turned inwards along 
the front margin and extends as far as the carina on the head, and there is sometimes an 
extremely minute tubercle at the point in question. The thorax is a little narrowed 
in front; the disc is rather coarsely punctate, and in front somewhat closely. ‘The 
punctures of the elytra are moderately coarse and the interstices narrow. The rather 
long pubescence does not prevent the surface from being shining. 
We have received a fair series of this species; it varies a little in colour, sculpture, 
and size. 
31. Gonicelus muticus, sp. n. 
Oblongo-ovalis, depressus, fusco-rufus, antennis pedibusque rufis; fortiter punctatus, pube elongata sat dense 
vestitus, subnitidus. 
Long. 24 millim. 
Hab. Mexico, Jalapa (Hége). 
The male of this species has no peculiar conformation of the head, which is coarsely 
punctured, and shining between the punctures. The thorax is strongly transverse, not 
broader than the elytra, coarsely punctate, the lateral punctuation but little different 
from the discoidal; lateral and anterior lines scarcely indicated. The elytra have 
the serial punctures unusually large and the interstitial punctures almost absent ; the 
pubescence is suberect, so as not to dull the surface. Four specimens. 
82. Gonicelus concolor, sp. n. 
Oblongus, minus elongatus, sat convexus, rufus, pubescens, minus fortiter punctatus ; prothorace transverso, 
anterius parum angustato, basi ante scutellum profunde depressa ; elytris post scutellum punctis numerosis, 
subtilibus, haud seriatis. 
Long. vix 3 millim.

This species is apparently destitute of salient peculiarities, though it may be distin- 
guished from G. angustus and others that are like it by the marginal lobe behind being 
placed lower than the disc of the thorax. This character, in combination with distinct 
and numerous fine punctures on the basal sutural part of the elytra, will probably lead 
to its recognition. We have received only two specimens, and they exhibit no 
character that may be distinctive of the male. It is perhaps nearest to G. segnis. 
The thorax is rather strongly transverse, broad in front, the anterior angles somewhat 
prominent, the punctuation fine, the anterior marginal line on each side quite’ short. 
The serial punctuation of the elytra is a little finer than usual. 
38. Gonicelus segnis, sp. n. 
Oblongo-ovalis, postice subattenuatus, subdepressus, piceus, ant ennis pedibusque rufis; minus fortiter punctatus,
