manuscript name. In the three specimens before me, which are from 

 Florida, the thorax is dark-brown on the disk with the side margins 

 and apex more or less pale, the elytra dark testaceous, with suture and 

 sides more or less brown ; the front and middle tarsal claws are simple, 

 the first interval is relatively coarsely and irregularly punctate and the 

 clypeus is not as concave as in semilivida Lee. 

 Anomala tibialis, new species. 



Larger, more robust and convex than parvula Burm., with more parallel elytra 

 and hind tibiae very short and triangularly dilated at apex. Head piceous, front paler, 

 clypeus dark testaceous, coarsely and closely punctate ; clypeus transverse, broadly 

 rounded in front and narrowly reflexed. Antennae moderate, club slightly shorter 

 than the preceding five joints. Thorax more than twice as wide as long, sides 

 narrowing to the front from before middle, nearly straight behind, hind angles 

 rounded, front angles not prominent ; disk convex, apical marginal bead nearly 

 obsolete at middle, basal marginal bead distinct, surface testaceous with two oblique, 

 dark, elongate markings at apex on each side of median line, the markings irregular 

 in outline and slightly curved outward, sparsely not coarsely punctate, the punctures 

 at sides and towards base nearly obsolete. Elytra elongate, parallel, testaceous, 

 suture and margin dark, surface sculpture and striae more or less obscured by trans- 

 verse rugae, the striae at sides more distinct and coarsely punctate. Under side 

 testaceous, shining, metasternum moderately densely clothed with long pale hairs, 

 abdomen with moderate punctures, which are not closely placed. Front tibiae 

 bidentate, apical tooth elongate and slightly curved, the upper tooth sharp and prom- 

 inent, the larger claw finely cleft, the upper and lower part equal in size ; the larger 

 claw of the intermediate tarsi finely cleft, the two parts equal in size ; hind tibiae very 

 short and distinctly shorter than the femora and broadly dilated towards apex. 

 Pygidium moderately punctate, punctures not deeply impressed. Length io mm., 

 width 5 mm. 



Texas, one female in collection Dietz. 



By the unusually short and broadly dilated hind tibiae this species is 

 easily distinguished from all our species. It is very closely allied to the 

 Mexican rhizotrogoides Blanch., but seems to differ from that species by 

 the more parallel form and the elytral sculpture.
