22O MEMOIRS ON THE COLEOPTERA 



raised lines rather strong; metasternal impression smaller than usual. 

 Female very much larger, more coarsely sculptured and stouter 

 than the male, almost similarly proportioned, except that the head 

 is smaller and that the antennae extend only to basal third of the 

 prothorax. Length (cf) 13.0-16.0, (9) 17.0 mm.; width (cf) 3.9- 

 4.8, ( 9 ) 5-6 mm. Mexico (Colonia Garcia, Chihuahua), Townsend. 



*erebea n. sp. 



6 Not very deep black and somewhat dull in lustre, the pubescence 

 largely denuded in the type but apparently coarse, yellowish- 

 cinereous and abundant beneath; head two-thirds as wide as the 

 prothorax, the punctures moderately strong, everywhere evenly 

 distributed and well separated, the median line striiform on the 

 front only; antennse very short, but little longer than the width of 

 the prothorax, the fifth joint as wide as long; prothorax barely at 

 all wider than long, the sides parallel and nearly straight in apical 

 half, rounding slightly at apex, rather abruptly converging thence 

 posteriorly, becoming sinuate to the tubulate base; punctures not 

 very coarse, widely separated, becoming still smaller and notably 

 closer medially, the median line unmodified; elytra three-fifths 

 longer than wide, fully two-fifths wider than the prothorax, deeply 

 but not very coarsely punctate, the punctures coalescent irregularly, 

 leaving broad flat irregular interspaces, which are dull in lustre, also 

 a flat and finely punctulate sutural margin, the raised lines obsolete, 

 the innermost alone evident though not elevated; metasternal im- 

 pression unusually large, elongate and deep, its median line finely 

 cariniform. Length 16.0 mm.; width 5.3 mm. Male unknown. 

 Washington State basalis n. sp. 



Because of the multiplicity of species in North America, these, 

 including mexicana of Bates, amounting so far as already known to 

 eight, it is probable that the genus Spondylis originated in North 

 America and extended to Eurasia in mid-Tertiary times by way of 

 the Alaska-Siberia land connection. 



I agree with LeConte that the position of Spondylis, near Parandra 

 in a distinct family group, is far more rational than as a member of 

 the Cerambycid series near Asemum, where it is placed by Bates; 

 it is correctly placed in the recent European catalogue near Parandra, 

 but in a simple tribal group of the Cerambycidae, which is inde- 

 fensible. Some other of the aberrant Cerambycids of Lacordaire 

 should also form distinct families of the Longicornia, such for 

 example as Hypocephalus.
