Corpus oblongo-cylindricum, alatum, squamulosum, pectore villoso, elytris subglabris. Clypeus concavus, 

 antice paulo latior, recte truncatus. Antennas 10-articulatse, articulis 3 et 4 aaqualibus, clava (feminae) parva 

 tripbylla. Labium profunde excavatum. Mentum paulo concavum, ligula latior. Palpi labiales in margine 

 ligulas inserti : maxillares articulo ultimo longiore cylindrico ad apicem acuto. Mandibulae parum prominulae. 

 Tibiae anticae fortiter tridentatae, intermediae extrorsum acute bidentatse, posticas crassiores denticulo lmo 

 acuto, denteque secundo transverso armatse, ad apicem spinulis coronatae, calcaribus complanatis, interno 

 minore angustiore. Tarsi (postici) breves, verticillatim setosi, articulis 1 — 4 sensim paulo brevioribus, 5to 

 primo aequali,unguiculis medio dente acuto mediocri armatis. Pygidium subtransversum triangulare, angulis 

 rotundatis. 



In every respect resembling Polyphylla, except in the antennas, the more thickened 

 posterior tibise, and the ungues. 



1. T. squamicollis, piceo-ferruginea, capite thoraceque confertissime punctatis, pilis depressis squami- 



formibus pallidis vestitis, hoc convexo, disco antice posticeque parcius villoso, elytris nitidis punctatis 



et rugosis parce brevissime pubescentibus, pygidio abdomineque squamulosis, pectore dense villoso. 



Long. 1-03. 



One female collected by T. Charlton Henry, M. D., U. S. A., at Albuquerque, New 



Mexico. 



Uniform reddish brown, with the tibise darker. Head densely punctured covered 

 with narrow yellowish scales ; front broadly margined, sides straight, slightly diverg- 

 ing, anterior margin nearly straight. Thorax convex, narrowed in front, much rounded 

 and subserrate on the sides, feebly broadly channeled about the middle of the disc, 

 vaguely impressed each side near the anterior angles : densely punctured, covered with 

 small narrow scales like those of the head, with long hairs intermixed towards the 

 base and apex. Scutellum densely pubescent with a glabrous line. Elytra rugous as 

 in most Rhizotrogi, not densely punctured, with a very short hair from each punc- 

 ture. Pygidium densely, abdomen less densely clothed with very small whitish 



* Fabricius has intended by his Melolontha occidentalis the European Anoxia australis ; Olivier confounded 

 them together as is evident by the localities given. His description does apply to the present, as the seven'jointed 

 antennal club of the male is mentioned
