R.UTELI1SLE 67 



much less than half as wide as the prothorax, densely punctato- 

 rugose, black, with green lustre and sparse punctures basally; clypeus 

 picescent, slightly wider than long, the sides broadly sinuate, 

 rapidly oblique from base to apex, the latter barely more than a 

 third as wide as the base, arcuato-truncate and gradually strongly 

 reflexed, the sides not at all reflexed, the suture straight, very dis- 

 tinct; eyes not prominent; antennal club almost as long as the stem; 

 prothorax about a fourth wider than long, the sides rounded medially, 

 thence straight and parallel to the base and strongly converging to 

 the apical angles, which are blunt at apex, the basal a little more than 

 right and not rounded ; basal bead feeble or subobsolete at the middle; 

 surface convex, black, with polished bright green lustre, the sides 

 flavate; punctures strong and deep, moderately coarse, rather ir- 

 regular and sparse; median line very feebly impressed, obsolete 

 basally; scutellum very minutely and sparsely punctulate; elytra 

 oblong-oval, slightly longer than wide, two-fifths wider than the 

 prothorax, with parallel arcuate sides, very pale brownish-flavate, 

 the sutural interval with feeble greenish lustre, the lateral edges 

 blackish; striae barely at all impressed, regular and strongly punc- 

 tured, thirteen in number; pygidium shining, with separated but 

 transversely interlacing asperulate lines and with sparse, erect, 

 silvery hairs. Male with the fifth anterior tarsal joint nearly as 

 long as the first four, the larger claw stout, the lower part broad, 

 obliquely truncate at apex, the upper rather thick basally, rapidly 

 finely aciculate, about as long as the lower and, at base, about half as 

 thick; hind tibiae feebly surate. Length (cf) 8.0 mm.; width 4.3. 

 mm. Mexico (Guadaljiro) *reflexus n. sp. 



This species differs from motaUescens in its much smaller size,, 

 very pallid elytra and strongly attenuated, gradually very reflexed' 

 clypeus, among other characters. The figure of metallescens given 

 by Bates, indicates a much larger head and more transverse pro- 

 thorax than in reflexus, though with nearly similar clypeus. 



Tribe RUTELINI. 



This tribe is composed of larger, more densely chitinized and 

 generally more brightly metallic species than the preceding and is 

 particularly well developed in the American continents, including 

 some of the most regally resplendent beetles of the world, belonging 

 principally to such genera as Plusiotis, Chrysina and Chrysophora, 

 as well as Anticheira, Ptenomala and Calomacraspis. But few of 

 these brilliant forms extend to the northward of our Mexican 

 boundary, and such genera as do so extend their limits, or are 

 peculiar to the nearctic regions, may be defined as follows: 



Pronotum with basal beading, generally strong and distinct throughout 

 the width. ?
