ART. XIII. — An attempt to classify the Longicorn Coleoptera of the part of America 

 North of Mexico. By John L. LeConte, M. D. 



(Continued from page 38.) 



Subdivision III. SPONDYLIDJ:. 



This subdivision consists of but very few genera, distinguished by very strongly 

 marked characters, and in Hypocephalus, exhibits the most aberrant forms of 

 Longicorn Coleoptera ; it vi^ould seem to be unconnected vv^ith any other group in the 

 existing creation, and might be regarded perhaps like anomalous forms among 

 quadrupeds, reptiles and fishes, as representative of a family nearly extinguished in 

 the lapse of time. 



The following table will express the relation between the genera contained in this 

 subdivision. The last joint of the tarsi in all the genera is more elongated than in 

 other Longicorns. 



Tibiae vix dilatatce, compressse, subtiliter serratas. SroNDYLis. 



Tibiae compressiusculae, apice expansse, posteriores dilatatse. Scaphinus. 



Tibije anticEe extus 3-dentatse, thorax lateribus armatus. Cantharocnemis. 



Tibiae anticas extus dentatae, thorax haud armatus. Hypocephalus.* 



SPONDYLIS Fabr. 



Antennae capite thoraceque fere longiores, articulis haud transversis. 



Oculi transversi, haud prominuli. 



Tibioe vix dilatata3, anticae calcaribus duobus aDqualibus. 



1. S. LATiCEPS. — Niger, dense punctatus, thorace minus convexo cordato, capite non latiore, obsolete 



carinato, elytris costis '6 vel 4 minus distinctis. Long. -75. 

 Lee. Agassiz Lac. Sup. 233. 



One specimen. Eagle Harbor, Lake Superior. Mr. Rathvon. The thorax is 

 much narrower behind, the base being scarcely half as wide as the apex ; the 

 punctures are coarse, and closely placed; the mandibles not longer than the head. 



Species ignota. 



2. S. upiFORMis. — "Elongatus, niger, crebre rugoso-punctatus, thorace subcordato, elytris lineis tribus 



elevatis ad apicem fere extensis. Long. 6 J lin." 

 Mannerheim Bull. Mosc. 1843, 304. 



Sitkha: "minoribus S. Buprestoidis individuis adhuc minor, angustior, thoracis 

 forma, et punctura omnium partium alia distinguendus." 



•To this subdivision probably belong Anoploderma and Sypilus i two South American genera described by 

 Guerin, Rev. Zool. 1840, p. 276.
