bb. Above nearly glabrous, shining testaceous. Form very elongate, 

 elytral spines long. .43-45 in unicolor, Rand. 



It is stated that E. vil- 

 / losum and E. para//elum are 

 not distinct, but they are in- 

 cluded in the above table, as 

 their amalgamation has not 

 yet been generally accepted. 

 The figures 19, 20 and 21 

 represent the three stages oi E. villosuin. 

 Tylonotus, Hald. 



Represented by T. bimaculatiis, Hald.; of 

 a brownish colour. .45 to .60 in. long. Each 

 elytron with two rather large, somewhat rounded 

 yellowish spots, one in front of the middle, the other sub-apical. The 

 thighs are yellowish except at base and apex, rather strongly clubbed. 

 The antennae are bisulcate (more distinctly on the third and fourth joints), 

 the thorax is thickly punctured with smoothish median line and two rather 

 large dorsal callosities. The elytra are coarsely, rather sparsely, punctured. 

 Pubescence thin, yellowish. The larva bores in ash; beetles have been 

 found under bark of the white or paper birch. 



Heterachthes, Newm. 



Easily recognized by the elongate form, shining surface and extremely 

 small second antennal joint. The thighs are strongly clubbed, the 

 antennfe long and heavy. H. quadrimaaclatus is .30 to .45 in. long, 

 brown or testaceous with two paler spots on each elytron, one in front of 

 and one just behind the middle. The pale specimens have the spots 

 indistinct. Head closely, elytra and thorax very sparsely, punctured. 

 Length, .30 to .45 inch. It has been bred from hickory limbs. 



Gracilia, Serv. 



G. minuta, Fabr., does not occur on any of the Canadian lists, but 

 has been described and figured (in the Canadian Entomologist, vol. 

 xxiii., p. 102), by Mr. J. ¥. Hansen. His figure (fig. 22) and description 

 are here reproduced. "It is of a uniform reddish-brown, the legs being 

 somewhat lighter, with rather sparse cinereous pubescence, giving it 

 a, heavy appearance. The antennae are ciliate, and the head, thorax an^
