Cryptarthrum, g. n. 



Cryphalo affine, discedens prothoracis basi et angulis posticis 

 marginatis, dorso baud evidenter asperate : tarsorum articulo 

 1" minuto, 2° majore, compresso, 3° parvo. 



Head concealed, not rostrate. Eyes oval, emarginate. Antenna 

 witb very sbort 4-jointed funiculus, the three distal joints trans- 

 verse, widened apically, club ovate, compressed, the sutures curved 

 on the inner, straight on the outer face, and ciliate. Prothorax 

 short, much narrowed in front and obtusely subacuniinate at apex, 

 the hind-angles and base finely margined, surface without evident 

 asperities. Elytra not overlapping the prothorax at base. Anterior 

 coxfe contiguous, the prosternal process short. Anterior tibiaj 

 widened from base to apex, and obliquely truncate, the upper mar- 

 gin sinuate, obsoletely toothed ; middle and posterior tibias with 

 the upper margin rounded, serrate. Tarsi short, the 1st joint very 

 small, the 2nd rather large, compressed and trigonate, the 3rd small, 

 the apical joint not so long as the preceding. 



The single species more nearly resembles a CrypTialus 

 than the species of any other genus. The available 

 examples were too few to permit of dissection, and the 

 examination of the tarsal joints proved unexpectedly 

 difficult, as the underside and legs were matted together 

 with some adhesive substance, probably derived from the 

 food-plant. 



Cryj)tartlirum xvall:erl, sp. n. 



Breviter oblongo-ovale, opacum, pallide fusco-testaceum, pilis 

 brevibus flavo-cinereis vestitum, antennis et pedibus testaceo-ferru- 

 gineis; prothorace alutaceo-ruguloso, anterius obsolete granulate ; 

 elytris dense multipunctatis et seriatim setosis. Long. 1*4-1"6 ram. 



Short oblong-oval, pale fusco-testaceous, dull, with short 

 moderately close cinereous-yellow pubescence mingled with 

 longer setae. Front darker, impressed, rugulose, thinly hairy ; 

 antennae pale ferruginous. Prothorax a half broader than long, 

 subbisinuate and finely margined at the base, the margin continued 

 along the subacute hind-angles to the middle of the sides, the latter 

 rounded throughout, strongly incurved and constricted anteriorly, 

 so that the apex appears obtusely augulate in the middle ; surface 

 uniformly and not strongly convex from base to apex, alutaceous,
