'IG Mr. Gilbert J. Arrow's Coniribulion to the 



anguslulus, of G(nstaecker, except iji size and a rather 

 greater elojigatioii in the latter, ami I am not convinced 

 of the separateness of the two species. 



The specimen from San Joachin, Guatemala, referred 

 to ".4. Uquefaclus by Gorham (Biol. Centr.-Amer. vii, p. 12G), 

 figures again two pages later in the same work as Anidryius 

 ? sp. It is very obviously different from A. liquefadas, 

 and Gorham is quite wrong in saying that it is without 

 an internal tooth to the front tibia, for there is a very 

 strong one produced by the abrupt dilatation of the apical 

 part, which is much less flattened and bent than in the 

 other male specimen described by him. This species may 

 be called 



Anidrytus guatemalae, sp. n. 



Gorham has given a descri])ti()j> of the unique specimen, 

 but besides the features mentioned by him it is considerably 

 longer and narrower than A. liqvef actus, more densely 

 punctured and pubescent, scarcely shining and with nnich 

 more slender legs and antennae. 



Length 8 mm. ; breadth 5 mm. 



Ephebus depress us Gorh., has all the characters of Ani- 

 drytus, to which it must be referred. As Gorham later 

 used the same specific name for a Guatemalan member 

 of this genus, tlie latter must be renamed and I propose 

 to call it 



Anidrytus decoratus, nom. no v. 



Anidrytus Jallacio.s us (Jorh., appears to be A. epliippium 

 Gerst., from wliich, although described from the same 

 region, Gorham did not attempt to distijiguish it. The 

 pronotum is not, as he states, more deeply punctured in 

 the middle than at the sides. This error, as well as the 

 general inadequacy of the description, was no doubt due 

 to the extremely dirty state of his specimen. 



The following new species is closely related to the last. 

 It appears to resemble none of the Peruvian species 

 described by Kirsch.
