4O MEMOIRS ON THE COLEOPTERA 



Group III. 



Subgenus Anomalopus nov. 



I have no representative of this subgenus before me and the 

 characters are drawn wholly from published descriptions. The 

 peculiar obconical form of the hind tibiae and their unusual brevity 

 would seem to show that it is by no means typical Anomala. The 

 type is the Mexican Anomala rhizotrogoides of Blanchard, with 

 which the following may be associated : 



Body larger, stouter and more convex than in parvula; head piceous, the 

 front paler; clypeus dark testaceous, coarsely and closely punctate, 

 transverse, broadly rounded at apex and with the edges narrowly 

 reflexed; antennal club (9 ) slightly shorter than the preceding five 

 joints; prothorax more than twice as wide as long, the sides nar- 

 rowing apically from before the middle, nearly straight basally, the 

 hind angles rounded, the anterior not prominent; surface convex, 

 the apical bead nearly obsolete at the middle, the basal distinct; 

 color testaceous, with two oblique dark elongate markings at apex, 

 "on each side of the median line," the markings irregular in outline 

 and slightly curved outward; punctures sparse and not coarse, ob- 

 solescent laterally and basally; elytra elongate, parallel, testaceous, 

 the suture and margin dark, the surface sculpture and striae more or 

 less obscured by transverse rugae, the striae laterally more distinct 

 and coarsely punctate; under surface testaceous, shining, the meta- 

 sternum moderately densely clothed with long pale hairs; abdomen 

 with moderate punctures, not closely placed; anterior tibiae with a 

 single external tooth, the apical process elongate and slightly curved, 

 the tooth sharp and prominent; larger anterior claw (9 ) finely cleft, 

 the two lobes equal in size, the larger claw of the middle tarsi finely 

 cleft, with the two lobes equal; hind tibiae short, distinctly shorter 

 than the femora, obtriangular, broadly dilated toward apex; py- 

 gidium moderately punctate, the punctures not deeply impressed. 

 Length (9) 10 mm., width 5 mm. Texas. One specimen in the 

 Dietz collection tibialis Schf . 



It is uncertain, from the language used in the original description, 

 whether there are two thoracic spots on each side of the median 

 line or whether it was intended by the author to indicate only one 

 spot at each side; the latter is the more probable. 



In the above review of the American species of Anomala, the 

 descriptions of peninsularis, antennata, clypealis and tibialis of 

 Schaeffer, which are unknown to me in nature, are derived 

 directly from the originals, generally with some alteration, trans- 

 position or abbreviation of language for the sake of lucidity, but 

 with careful avoidance of change of meaning or omission of important
