AMERICAN COLEOI'TERA. 141 



angle with the base the point of the angle being rather obtuse. The 

 presence of accessory ambulatorial setse and absence of menturn tooth 

 will place the species at the end of our series as at present arranged, 

 in association with the somewhat aberrant testaceus and gravis without 

 however having much relationship with either. 



Occurs at Fort Bayard, New Mexico. 



Near this species should be placed Fio&oma cordatum Lee. The 

 male has the middle and anterior tarsi dilated and papillose beneath 

 as in Harpalus, the abdomen has accessory ambulatorial setae, the 

 menturn without tooth and finally a dorsal puncture as in obliquus. 

 It will be known from all our species of Harpalus by its reproduction 

 of the form of Cratacanthus duhius. 



XEMOMYCETES n. g. 



Tarsi subtetramerous. Ligula as broad as long, truncate at tip. Antennae 

 with three-jointed loose club rather abruptly formed, the ninth and tenth 

 joints not prolonged on the inner side, first joint obconical, second much 

 shorter, third cylindrical nearly as long as the next two together, joints 4 — 8 

 nearly equal, about as wide as long, joint nine a little larger in the male and 

 somewhat larger than the tenth, in the female equal to the tenth and less 

 suddenly broader than the eighth, eleventh obtusely oval a little larger than 

 the preceding. Palpi with terminal joint obtusely conical. Prosternum nar- 

 rowly separating the coxae, carinate between them and slightly prolonged at 

 tip. Mesosternum moderately long and strongly carinate, slightly bifurcate 

 behind to receive the raetasternum. Prothorax without subniarginal line or 

 longitudinal discal grooves, transverse basal impression moderate ending ab- 

 ruptly but not in fovese. Form oblong, inconspicuously pubescent. First joint 

 of tarsi not elongate, second shorter and prolonged beneath, last joint longer 

 than the others together and with simple claws. First and fifth segments of 

 abdomen elongate, the intermediate three short and equal. 



The above genus is proposed for a species which must be referred 

 to the Lycoperdinites of Chapuis or the more comprehensive tribe 

 Dapsini of Gerstaecker. The entire absence of grooves on the thorax 

 excepting the transverse basal, places it in some relationship with 

 Folymnus and Heliobletiis, the latter especially, but even here there 

 are short longitudinal grooves. This latter character is the only one 

 on which I can at present rely for the separation of the two genera, 

 together with the fact that the Heliohletus is from Borneo and on 

 comparison would doubtless show other differences. 



X. iflorrisoni n. sp. — Oblong, moderately elongate, ferruginous, moder- 

 ately shining, very sparsely clothed with inconspicuous pubescence. Head 

 sparsely punctate. Antennae a little longer than the head and thorax. Thorax 

 a little broader than long, apex emarginale, sides in front feebly arcuate, pos- 

 teriorh' slightly sinuate, hind angles acute, base truncate, surface very sparsely 

 punctate. Elytra oblong not wider at base than the thorax, sides feebly area
