CETONIIN/E 331 



fourth wider than long, the sides becoming subparallel basally, the 

 basal sinus not so deep as in the preceding species; punctures rather 

 coarse and dense, becoming sparse medio-basally, wanting along the 

 base, without trace of an impunctate median line; scutellum smooth; 

 elytra slightly broader at the humeri, with the usual deep sinus, dis- 

 tinctly elongate, sometimes feebly cuneiform, the costae very feeble, 

 the first sulcus with sparse, elongate-elliptic and posteriorly open 

 incised annuli, tending to biserial arrangement, the second with 

 similar but less narrow annuli, the flanks with deep and well separated, 

 transversely lineiform punctures; toward apex, the annuli of the 

 deeper sulcus adjoining the sutural carina become very elongate and 

 rather confused; pygidium with dense concentric strigilation; an- 

 terior tibiae with the teeth rather short and obtuse, the lower two but 

 slightly more approximate; hind tarsi (cf) as long as the tibiae. 

 Length (cf 9) 9.7-11.0 mm.; width 5.5-6.0 mm. Mexico, Panama 

 and Ecuador. [ Cetonia dimidiata G. & P.] . . *dimidiata G. & P. 

 Body nearly as in dimidiata in form, sculpture and size, but differing in 

 color and in the punctured scutellum, piceous-black, shining, sparsely 

 clothed with very short inconspicuous pubescence; head coarsely and 

 densely punctate, the clypeus more sparsely, the latter a little wider 

 than long, with feebly arcuate sides and broadly rounded angles, the 

 apical margin slightly reflexed and feebly sinuate at the middle; 

 prothorax oval, narrowed in front, broader than long, the sides 

 evenly arcuate, the base sinuate at the middle; surface moderately 

 convex, coarsely but not densely punctured; scutellum coarsely 

 punctured at the sides; elytra moderately convex, subbicostate, the 

 intervals with variolate foveae, which gradually become simple punc- 

 tures toward the sides; sutural angles right; under surface sparsely 

 clothed at the sides with yellowish hair, the abdomen very sparsely 

 punctate and with a few hairs at the sides; tibiae slightly fimbriate 

 within; pygidium concentrically strigose; mesosternal button punc- 

 tured and hairy beneath and in front; anterior tibiae tridentate in 

 both sexes, the two lower teeth more approximate; antennal club 

 nearly as long as the rest of the antennae; males smaller and narrower 

 than the females. Length 10-12 mm. Texas (San Antonio).

The species described above as childreni answers to the descrip- 

 tion and figure given by the authors very well and, as there is no 

 record of species of this particular section being found south of 

 Nicaragua, it is highly probable that the locality attached by label 

 to my single specimen is erroneous, especially as a typical example 

 of the essentially Mexican dimidiata has the same locality label. 

 If childreni and thelasco, as here described, are correctly identified, 

 they are different species beyond any reasonable doubt. This 

 childreni section, composed of very small pubescent species, is a 

 difficult one to deal with, especially in the absence of the five
