tomentous border of elytra is dilated suddenly shortly before the 

 apex in dimorphogyTms, while it is gradually broadened in mexlcanus.

Described from Guatemala, Torola (Champion). I have seen a 

 good series in the Hamburg Museum for Guatemala, Hacienda 

 Trapiche Grande near Cuyotenango (Riedel collector. Dr. G. v. 

 Sydow leg.). The United States National Museum possesses 

 numerous specimens from Mexico, Cordoba, Vera Cruz, April 17, 1908 

 (Fr. Knab coll.) comprising 34 males and only three females, which 

 exhibit the strongly alutaceous surface of elytra, which was indicated 

 by the describer of the species. 



GYRETES MINOR forma LAEVIPENNIS, new female form 



Other females of the same series have the hairless parts of elytra 

 polished like the males, from which they are easily distinguished 

 by the narrow anterior tarsi; moreover the tomentous border of 

 elytra is apically more enlarged in these females. 



Type and six paratypes (Cat. No. 41244, U.S.N.M.) in the United 

 States National Museum, three paratypes in collection of the author.

ORECTOCHILUS OBSCURICEPS Regimbart 



Orectochilus ohscuriceps Regimbart 1907, Ann. Soc. Ent. France, vol. 76,

Described from Central China, Szechuan, Siao-Lou (Coll. Ober- 

 thiir and Regimbart). The United States National Museum pos- 

 sesses three specimens from Manchuria and Korea: Yalu River 

 150-200 miles from mouth, May, 1914 (A. D. C. Sowerby), which 

 agree very Avell with Regimbart 's description and may probably be 

 referred to that species. As, however, I do not possess authentic 

 specimens of the latter, I can not decide the question with certainty.
