AMERICAN COLEOrXERA. 87 



Miilc. — As in loiifficorni)!, first joint of anterior tarsus distinctly 

 dilated. 



I have seen but one specimen, collected by the late G. R. Crotch in 

 British Columbia. 



AXACYPTIS n. g. 



AnteniKC short, ton-jointed, fir^t two joints stout, joints three to 

 seven foriuin^j a rather close f'unicle with the joints gradually wider, 

 last three joints forming a rather sudden club of elongate oval form, 

 the first joint conical, second transverse, the terminal oval at tip and 

 pubescent at its apical half with rather long pubescence. Maxillary 

 palpi with the first joint very small, second moderately long and 

 slender, third elongate oval, truncate at tip, fourth slender, subulate. 

 Eyes moderately prominent, rather coarsely granulated. Me.sostornum 

 in front of coxtB short, not concave, distinctly carinate at middle, the 

 coxa; narrowly separated. Metasternum posteriorly rectangularly trun- 

 cate. Hind cox;"e as in Ili/poci/ptus, but with large articular plates 

 concealing nearly half the femur. Klytra expanded beyond the body, 

 epipleura3 broad but vertical. Abdomen very feebly margined. Tarsi 

 four-jointed. 



A very ren)arkable genus seeming to exhibit some affinity with the 

 Trichopterygidae notably Limuhdas. The joints three to seven of the 

 antennae are conjointly very little longer than the second. 



We have but one species in our fauna, but several that have been 

 described as lIijpor//ptas from Europe and elsewhere seem to belong 

 here. 



A. testaceilS, Lei-. — Rufo-testaccous, moderately shining, sparsely pubes- 

 cent, convex. Head broad, smooth, sparsely pubescent. Antennae not as long 

 as head and thorax. Thorax twice as wide as long, convex, very sparsely punc- 

 tured and fiubescent, base slightly sinuate on each side, hind angles sub-acute 

 and sifghtly jtrolouged. Elytra each wider than long, arcuately narrowing to 

 apex; apex conjointly emarginate, surface finely punctured in a very regular 

 quincunx, the punctures connected by very fine oblique lines, sparsely pubes- 

 cent. Abdomen feebly margined, sparsely punctured and pubescent, beneath 

 slightly darker in color. Boily beneath concolorous, metasternum and articular 

 plate of hind coxae punctured in regular quincunx. Length .Oo inch; three- 

 fourths mm. (fig. 3). 



The resemblance superficially in color and form to Limulodes para- 

 doxus is still further increased under the lens by the peculiar sculpture 

 of the elytra which is nowhere else seen in the tribe. The expansion 

 of the elytra downward beyond the body also resembles that insect, 

 but beyond these points all resemblance ceases. 



Four specimens from Georgia and three from Arizona, exhibit no 

 specific difi'orences.
