deciduous. Abdomen sparsely punctate, the first seg- 

 ment transversely wrinkled. Legs paler, sparsely hairy. 

 Length, .16 inch; 4 mm. 



This species may be compared in facies to a small Per- 

 itaxia riigicoUis, and almost equally to an elongate Ex- 

 omias pe/Iucuiits. I place it in Thricolepis temporarily 

 to avoid the necessity of erecting a genus for each new 

 species. Unfortunately, the Le Conte system of classi- 

 fication of the Curculionida?, as a whole, is so radically 

 different from that of Lacordaire that it is impossible to 

 correlate the genera, especially of the Otiorhynchidaj, 

 without actual comparison ; and the more genera estab- 

 lished on unique species and specimens, the greater will 

 be the confusion in the future. 



Two specimens. San Julio. 



SCYTHROPUS DELICATULUS n. Sp. 



Form rather slender, densely clothed with pale green, 

 oval, pearly scales. Antenna pale testaceous. Head 

 with few short erect hairs, especiall}' on the beak. 

 Thorax very little wider than long, sides very feebly 

 arcuate. Elytra widest behind the middle, disc finely 

 striate, the punctures closely placed, intervals slightly 

 convex. Bod}- beneath less densely scaly, the scales 

 more metallic. Legs pale honev yellow. Length, .14 

 inch; 3.5 mm. 



A small, delicate species, with a facies of some of the 

 European Phyllobius. 



El Taste. 



MiTOSTYLUS GRACILIS n. Sp. 



Form rather slender, densely clothed with ashy white 

 rounded scales, elytra often maculate or banded with 

 black. Antenna; pale brown. Head with numerous
