Resembles closely the figure of Obrium cribripenne Bates in Biol. 

 Centr. Am., vol. V., but while the elytra is brown in the figure'it is 

 according to the description " nigro-violaceis. " 



Differs from Linell's mozinncE by the uniform brown color, the 

 confused punctuation of elytra and the smaller head. 



Both species inozin/ice and brunneiun may be considered inter- 

 mediate between the true Obrium and Phyton both have the apical 

 part of thorax little wider than the basal part. 



Neoclytus magnus, new species. 



Elongate brown ; thorax darker, at middle with a yellowish white fascia, base, 

 apex and sides densely pubescent with white hairs; elytra with two straight and one 

 oblique white fascia. Head very finely and very densely punctured, above the antennal 

 tubercles and cheeks coarsely punctured, antennae reaching the first elytral fascia, joints 

 three and four slender, the outer joints shorter and broader and gradually decreasing in 

 length. Thorax as long as broad, base and apex equal, sides slightly arcuate, disk 

 moderately coarsely and densely punctured, with three "rows of well defined transverse 

 rugae, one at middle and one on each side, below which the disk is depressed, those 

 at side sinuate at middle and oblique at base. Elytra two and a half times as longas 

 broad, narrower than the thorax at middle, sides nearly straight, slightly narrowing to 

 apex which is arcuate truncate, the sutural angle rounded, the outer slightly acute. 

 Beneath clothed with white hairs, denser at sides of prosternum, metasternum and 

 abdomen, the latter finely and densely punctured. Legs long and slender, femora 

 without spines, hind tibiae and tarsi compressed, first joint of hind tarsi longer than 

 the following ones together. Length, 20 mm. 



Ensenada, Lower California. One female from Mr. G. Beyer in 

 the Museum of the Brooklyn Institute. 



Another specimen in Mr. Beyer's collection has the thorax and 

 elytra blackish, the base of elytra reddish-brown and the bands yel- 

 low, but besides the color there is no other difference. 



Ataxia spioicauda, new species. 



Elongate, nearly parallel, piceous, elytra broadly, deeply and conjointly emargi- 

 nate and hispinose at apex, covered densely with white and ochreous short hairs. 

 Head densely clothed with white and ochreous hairs ; antennae nearly as long as the 

 entire body, basal joints piceous, the following paler at base, densely pubescent with 

 fine short white hairs, with larger hairs sparsely intermixed. 'Ihorax nearly as long 

 as wide, feebly narrower at apex than at base, sides slightly arcuate with a small 

 spine at middle, disk finely and densely punctured, with a few larger punctures inter- 

 mixed, a longitudinal impressed line interrupted at middle, densely clothed, white 

 short hairs generally abraided at middle and two denuded round spots on each side 

 near base. Elytra three times as long as the thorax, slightly narrowing to apex, 

 apices conjointly, deeply, broadly emarginate and Jspinose ; disk with a costa near 

 suture, obliterated at base, finely and densely punctured, with a few coarse punctures
