RUTELIN.E 3 



Rutelids of Central America. The tarsal claws are greatly diversi- 

 fied, but both claws of the posterior tarsi are invariably simple, the 

 larger never cleft as it generally is in the South American tribe 

 Geniatini, which could very well immediately follow the Anomalini 

 in the series as before stated, because of the membranous elytral 

 margins, and not be separated therefrom by the tribe Rutelini. 



In the following generic analysis of the tribe Anomalini, only 

 such North and South American genera are included as are actually 

 represented by material in my collection : 



Mesosternal epimera not ascending before the elytral humeri 2 



Mesosternal epimera narrowly and inconspicuously ascending in front 

 of the humeri; larger claw of the first and second tarsi always cleft, 

 more unequally in the male as usual; ligula broad 6 



2 Ligula small and narrow, entire at tip; tarsal claws all entire, never 

 cleft 3 



Ligula large and broad, generally more or less sinuate at tip 4 



3 Clypeus long, rounded; anterior thoracic angles rounded; body 

 moderately large in size, pale, glabrous. Sonoran regions. [Type 

 Anomala cavifrons Lee.] Rhombonalia 



Clypeus short, deeply concave, broadening to the base; anterior thoracic 

 angles acute; body very small in size, with thin pale integuments. 

 Florida. [Type Anomala semilivida Lee.] Anomalepta 



4 Labrum sharply inflexed, the exposed edge thin; clypeus rather long, 

 the upturned apex feebly sinuate medially; ligula very large and 

 transverse, broadly and angularly emarginate at apex; body cunei- 

 form, with thin pale integuments; larger claw of the first and second 

 tarsi not properly cleft but with an inclined acute tooth beneath 

 near the apex. Sonoran regions. [Type A. cuneata n. sp.] 



Anomalacra 



Labrum not sharply inflexed. the exposed edge obtuse, integuments, 

 claws and habitus greatly diversified * 5 



5 Mesosternum between the coxae flat or but feebly convex, the meso- 

 metasternal suture always evident. Cosmopolitan. [Type Scara- 

 b&us ceneus DeG.] Anomala 



Mesosternum tumid and smooth between the coxae, more or less anteriorly 

 prominent and sometimes greatly produced, gradually acuminate 

 and anteriorly porrect; meso-metasternal suture obliterated; body 

 with rather thicker and more metallic integuments than the American 

 species of Anomala. North and South America. [Type Melo- 

 lontha marginata Fabr.] Spilota 



6 Clypeus normal, broadly trapeziform, rounded or anteriorly dilated. 7 



Clypeus narrowed and reflexed anteriorly, rhiniform 1 1 



7 Hind tibiae constricted apically or surate as in Anomala; body oval, 

 convex, pubescent throughout; clypeus broadly rounded, not 

 narrowed basally; mesosternum broadened and feebly convex be- 

 tween the coxae but not tuberculiform. Mexico. [Type Anomala 

 villosella Blanch.] . *Lamoana
