flat, erect setae or scales, short on anterior disk, but becoming larger 

 posteriorly ; each elytron with a dense group of coarse, piceous-brown 

 setae behmd the anterior margin. Declivity evenly arched, not sulcate ; 

 first striae more strongly impressed, as on disk ; punctures finer. 



Ventral surface shining, piceous ; clothed with nearly white, usually 

 bifurcate, recumbent scales anterior to third abdominal segment, last 

 three segments with erect, fuscous scales except at the sides of the 

 third. Foretibia (fig. 18, k) with eight occasionally nine) rather 

 short, stout teeth on outer margin. 



Male. — Similar in size and habitus to female, but with the frons 

 strongly concave and with longer hairs at sides and above; antennal 

 club larger and more slender, 2.28 times as long as wide; last abdom- 

 inal segment slightly shorter, with the setae parted in median line. 



In this species the chief variations are in the size and in the color 

 pattern formed by the light and the dark-colored scales. 



Type locality. — Guadalajara, Jalisco, Mexico. 



Other locality. — Mexico. 



Host. — Eysenhardtia sp. 



Type material. — Holotype, allotype, and 136 paratypes, U.S.N.M. 

 No. 52955. 



Remarks. — The type, allotype, and 11 paratypes are from Guad- 

 alajara, Mexico, intercepted at quarantine, Nogales, Ariz., in packing 

 crates made of Eysenhardtia sp. (wood determined by Prof. S. J. 

 Eecord) ; 48 paratypes from Eysenhardtia sp. (determined by W. N. 

 Watkins), Mexico, September 11 and 24, 1936; 77 other paratypes 

 were intercepted at quarantine from Mexico, but there are no data 

 either as to host or locality of origin. 



RENOCIS BRAZILIENSIS, new species 



Figures 17, o; 18, I, m. 



Female. — Keddish brown, clothed with light-cinereous, nearly 

 white scales and setae ; 1.31 to 1.63 mm. long ; holotype 1.48 mm. long, 

 1.7 times as long as wide. 



Frons with a very small median point on epistomal margin, with 

 fringe of rather fine, yellow-cinereous setae extending halfway to 

 tips of mandibles; arcuately, transversely impressed above epistoma, 

 with center of frons flat, sides and vertex rounded; surface reddish 

 brown, moderately shining, finely, densely granulate-punctate; sur- 

 face partly concealed by rather short, stout, cinereous setae, only 

 slightly longer at the sides and above. Eye about 3.5 times as long 

 as wide, finely granulate, inner margin sinuate, subemarginate. 

 Antenna (fig. 17, o) with club broad-oval, 1.58 times as long as wide,
