328 MEMOIRS ON THE COLEOPTERA 



with rather acute but only moderately oblique equidistant teeth, the 

 uppermost very much smaller than the others though acute. Length 

 (9) 10.0 mm.; width 5.6 mm. Ecuador (Babahoya)?. [Cetonia 



childreni G. & P.] *childreni G. & P. 



4 Elytra with conspicuous spots and lines of tomentum 5 



Elytra wholly devoid of tomentose spots 8 



5 Clypeus gradually and conspicuously narrowed from base to apex, 

 the latter relatively very narrow and rounded, slightly thickened 



but not reflexed 6 



Clypeus less strongly narrowed to the apex, which is broadly obtuse, 

 barely reflexed and very feebly, though more or less evidently, 



bilobed 7 



6 Body small, narrowly oblong-oval, convex, shining, black, the upper 

 surface with short and rather inconspicuous erect hairs, becoming 

 long and rather dense on the sterna and toward the sides of the ab- 

 domen; elytra each with a large red spot from the sides basally nearly 

 to the suture and scutellum; head with close shallow rugulosity and 

 with short sparse hairs almost evenly throughout; prothorax convex, 

 about a fourth wider than long, the sides almost evenly rounded, 

 oblique anteriorly, parallel basally, with rather coarse but shallow 

 punctures, close and obliquely confluent laterally, sparser medially, 

 where there is an ill-defined impunctate line expanding at base; 

 sides with a narrow line of tomentum; scutellum broad, triangular, 

 smooth, about a fifth as long as the -elytra, the latter longer than 

 wide, with very sparse hairs and feeble, broadly tumid costae, the 

 inner sulcus with two double incised lines, with an intermediate 

 row of punctures, the outer sulcus with confused and elongate- 

 elliptic deep annuli; the flanks with sparse crescentic punctures; 

 in about outer half and apical three-fifths there are six or seven close- 

 set transverse tomentose lines and, at apex, a broader line; pygidium 

 strongly, evenly tumid, with the crest below the centre, entirely 

 covered with tomentum, except medially from the tumor to the apex, 

 the tomentum with irregular and well separated incised concentric 

 lines; abdominal segments each with a transverse tomentose area 

 toward the sides, not attaining the segmental apex; two lower an- 

 terior tibial teeth large, rather more distant than the upper two, the 

 uppermost feeble, the tarsi short. Length (cf ) 9.2 mm.; width 5.0 

 mm. Mexico. [ Cetonia canescens G. & P.]. ... *canescens G. & P. 

 Body larger and much stouter than in canescens, but almost similar in 

 general characters and in the tomentose areas, black or piceous- 

 black, rather shining, the elytra very indefinitely and not strongly 

 rufescent in about basal half, except near the suture and scutellum; 

 pubescence much shorter, coarser, sparser and less visible than in 

 the preceding, on the sterna and sides of the abdomen less dense 

 than in that species and not so long but very coarse; head more 

 opaque, finely but more definitely punctate, the clypeus not quite 

 so sharply acuminate, the apex more rounded ; prothorax much larger, 

 fully a third wider than long, the sides feebly converging to three- 

 fifths, then strongly oblique to the apex; punctures coarser, deeper 

 and laterally much less close-set than in canescens, the median line
