TAPHRIDERES.—CERYLON, 491 
1. Taphrideres alternans, sp. n. (Tab. XV. fig. 21.) 
Niger, haud depressus, tenniter setosus, nitidus; antennis rufis, pedibus piceis; prothorace ante basin in medio 
profunde foveolato ; elytris subtiliter seriatim punctatis, interstitiis primo, tertio, quinto levigatis, alternis 
Setigeris, 9 ~ ee . , 
Long. 4-44 millim. 
Hab. GuateMata, El Tumbador, Las Mercedes, Cerro Zunil (Champion). 
Antenne obscure red, stout. Eyes large, convex, placed near the thorax. The latter 
rather elongate, much narrower behind ; the sides rounded in front; the anterior angles 
acute; there is no lateral margin, except at the sides behind, where there is a short 
elevated plica; in front of the base in the middle there is a very deep fovea; the surface 
is coarsely punctate, but shining, and very distinctly setigerous. Elytra with the second 
and sixth interstices prominent at the base; the sculpture consists of series of fine, 
setigerous punctures, and a similar but still finer punctuation of the interstices, the 
alternate interstices being, however, smooth; the first interstice becomes depressed at 
the apex, and is there slightly transversely plicate. Under surface shining, with fine 
scanty hairs. This species is apparently confined to the Pacific slope. 
Subfam. CERY LINZ. 
In this group the antenne have their insertion exposed from the front, and the 
terminal joint of the palpi is very minute and aciculate. The subfamily Ceryline com- 
prises a considerable number of genera, which require a careful study, as the gradations 
in the minor points of strueture appear to be numerous. All are small or minute 
Colydiids.

This genus is very widely distributed, but only three or four species have been 
described from the Western Hemisphere. 
1. Cerylon curtipes, sp. n. 
Depressum, breve, castaneum, nitidum, fortiter punctatum ; elytrorum seriebus externe et versus apicem 
carentibus. 
Long. 2 millim. 
Hab. Mexico, Motzorongo (Flohr); Guatumata, San Gerénimo (Champion). 
Antenne short; club rather small. Eyes very prominent. Thorax broader than 
long; front angles very little produced; hind angles rectangular; disc coarsely 
punctate; basal impressions absent. Elytra with six series of coarse punctures, the 
sides and apex smooth. Legs short; tibie dilated and rounded externally towards 
the apex, each bearing two long, very fine sete.
