ANILLUS.— PEEICOMPSUS.

ANILLUS. 



■ 



Anillus, Jacquelin Duval, Ann. Soc. Ent. Fr. 1851, Bull. p. 72. 



■ - 



A genus of minute blind beetles, allied to Taehys, hitherto found only in the Medi- 



terranean 



region 



and in North America. Ten species have been described. 



The 



following differs from the typical forms, and also from the allied genera Scotodijpnus 

 and Illaphanus in its convex surface, and in the elytra being rounded, not subtruncated 

 at the apex. By the absence of striae or distinct rows of punctures, and by the scarcely 



perceptible terminal joint of the palpi, it 



agrees better with 



Scotodijpnus than with 



Anillus ; but in the former of these two genera the elytra are much abbreviated, which 

 is not at all the case with our species. 



1. Anillus integripennis. (Tab. VI. fig. 5.) 



Minutus, oblongus, subconvexus, breviter setosus, flavo-testaceus, subnitidus ; foveis frontalibus elongatis, sat 

 profundis, interspatio subangusto convexo ; antennis robustis, moniliformibus, versus apicem subincras- 

 satis; thorace quadrato, postice parum angustato, angulis posticis rectis, basi depressa transversim 

 sulcata ; elytris oblongis, apice subabrupte declivibus, subtilissime punctulatis, striis nullis, in loco striolae 

 recurvae punctis magnis tribus.

PERICOMPSUS. 



Pericompsus, Leconte, Ann. Lye. N. York, v. p. 191 (1852) ; Schaum, Berl. ent. Zeitschr. I860, 



p. 201. 



Eighteen species of this genns have been described, all American, and ranging 

 through temperate as well as tropical latitudes, north and south. A closely allied 

 undescribed genus occurs in Australia, of which Tachys australis, Schaum, is the type, 

 differing from Pericompsus only in the eighth and ninth elytral striae being separated 



and not sunk together in a marginal groove.

2. Pericompsus juenndus. 



Pericompsus jucundus, Schaum, Berl. ent. Zeitschr. I860, p. 202 l . 



Hab. Mexico, Tuxtla (Salle), Vera Cruz (Salle, H'dge) ; Guatemala, Izabal (Salle), 

 Champerico (Champion). — South America, Venezuela *. 



A Guatemalan specimen in the Salle collection is referred to this species. All the 

 examples I have examined agree with Schaum's description as far as it goes.
