HARPALIN^E 217 



Probably related to calathoides, but the thoracic apex is much 

 narrower than the base in that species and not subequal in width 

 as might be inferred from the description of flebilis; this, when 

 considered in connection with the facts that the tip of Lower Cali- 

 fornia is in a somewhat different zoological region from Arizona and 

 the rest of the California Peninsula and that the species are some- 

 what numerous in the Sonoran regions, renders actual specific 

 identity in this case highly improbable. 



Spongopus Lee. 



This genus is also one of the more distinctly characterized 

 members of the Anisodactylini, having a facies entirely its own, 

 due to the short cordiform prothorax and large and very elongate 

 elytra, when compared with the anterior parts. It is allied closely 

 to Anisotarsus, but differs in the dense hard integuments among 

 other features. The mentum tooth is only moderate in size as in 

 Anisotarsus, but is triangular, clearly denned and constant. The 

 ligula is rather slender and is gradually and only very slightly 

 broader apically; the paraglossae are an extreme development of 

 forms frequently observed in the tribe, the outer part of the apex 

 being greatly prolonged into a slender process, extending far beyond 

 the tip of the ligula and with its apex somewhat curving inward. 

 The labial palpi are long and slender, the third joint but little 

 shorter than the second, which has many long bristling setae along 

 its anterior side as usual in the tribe. The terminal spur of the 

 anterior tibiae is long and very slender, but nevertheless has the 

 posterior side arcuate basally, while the anterior side is almost 

 perfectly straight. The hind tarsi are long, with some irregular 

 punctures and short hairs dorsally, the first joint about as long as 

 the next two and equal to the fifth, the claws strongly arcuate and 

 well developed. The elytra have a fine suffused punctulation, but 

 the abdomen is smooth, excepting the usual fine post-coxal punc- 

 tures. The type species may be known by the following characters: 



Body above and beneath rather deep black, strongly shining throughout 

 above in both sexes, there being absolutely no apparent sexual 

 difference of any kind; legs and antennae rufo-testaceous; head 

 evidently more than half as wide as the prothorax, almost smooth, 

 with very prominent eyes and unusually large deep irregular foveae, 

 which have a ramus curving outwardly, generally almost to the eyes; 

 antennae long, rather slender; transverse red spot of the vertex
