than second, 4-5-6 gradually shorter, 7-10 quadrate or more trans- 

 verse, eleventh longer, oval, obtuse at tip. Maxillary paljii stout, 

 second joint elavate, third ovate, fourth conical, acute and scarcely 

 longer. Thorax quadrate, not narrowed in front, apex truncate, base 

 arcuate, without ante-basal discal impressions. Elytra wider at base 

 than the thorax, oblong oval, widest at middle, surface coarsely and 

 densely striato-punctate, with a more or less distinct oblique impres- 

 sion on each elytron. Prosternum rather narrow between the coxse, 

 dilated behind them, the cavities rather widely closed behind. Me- 

 sosternum distinct, oblique. Abdominal segments free, 2-3-4 equal 

 in length. Legs moderately stout, the posterior femora broadly oval. 

 Anterior and middle tibiae scarcely wider at tip, the posterior tibiiB 

 with the posterior edge rounded, dilated at tip, a small tooth above 

 the dilatation, the apex distinctly prolonged beyond the insertion of 

 the tarsus and with a small spur. Posterior tarsi nearly as long as 

 the tibia, first joint obconical, very narrow at base, second smaller 

 in front, but moi-e depressed, third elongate oval, not bilobed, fourth 

 nearly as long as the preceding, abruptly inflated at apex, the claws 

 toothed at middle. Claws of anterior and middle tarsi bifid, the 

 inner division shorter and curved inward. Body pubescent and 

 with erect hairs. 



The above description is drawn from our species alone. Chapuis 

 remarks that the species are often quite dissimilar, and their study, 

 from a generic standpoint, of some difficulty. Some differences have 

 been observed between his generic description, and that above given 

 for our species, more, however, in the omissions in preceding descrip- 

 tions to mention especially the form of the hind tibiae at apex and 

 the form of the claws. As Hamlet Clark, the author of the genus, 

 has seen our species and considered it a true Hypolampsis, I feel 

 unwilling to do more than say that the species seem to need more 

 careful study generically. 



Two species are known to me in our fauna : 



Thorax roughly punctured, wider than long; elytra uot striate pilosa. 



Thorax eveuly punctured, as loug as wide; elytra broadly striate IVIellyi. 



H. pilosa Illig. Oblong oval, convex, opaque, variable in color from testa- 

 ceous to piceous black ; surface with recumbent pubescence and more sparsely 

 placed erect hairs. Anteniise lufotestaceous or brownish, the outer five joints 

 always darker, sometimes black. Head densely punctate and rugose, the tuber- 

 cles alone smooth. Thorax quadrate, very little wider than long, not narrowed 

 in front, sides straight or slightly sinuous, anterior angles obtuse to the front,
