1276 COLEOPTEBA 



1000. ^E. simplicollis, Broun. Dr. Sharp gives a description 

 of the female, and states that " the thorax is just about as broad as 

 it is long ; it has no transverse grooves, but at each side near the 

 front there is a slightly -raised, shining, tubercular space, and nearer 

 the middle, nearly in a line with it, a larger rugose elevation ; on the 

 middle there is another feeble elevation, becoming linear in front, 

 and on the basal portion some obsolete inequalities." 



Christchurch, Wakefield ; Picton, Helms. One example from 

 each source. 



2246. JE. miltica, n.s. (Sharp ; Trans. Boy. Dub. Soc., 1886, 

 p. 439.) Angustior, ferruginea, griseo-vestita, antennis pedibusque 

 cum tarsis concoloribus ; prothorace cylindrico, fere esculpturato, 

 opaco, tenuiter pubescens. 



Long. llmm. 



This is the most slender of the species, and may be readily known 

 by the almost complete absence of thoracic sculpture, the surface 

 being feebly uneven, with an obscure slight carination of the disc. 

 The male has the sides of the thorax a little rounded, but in the 

 female they are straight ; the former sex has the flanks of the pro- 

 notum punctate, and all the prosternum, except the front, similarly 

 punctate ; the supplementary segment is like that of &. plicicollis. 



Picfon. Helms ; one pair. 



Sect. 2. Prosternum punctate in the male sex, impunctate in 

 the female. 



2247. JEj. plicicollis, n.s. (Sharp; Trans. Boy. Dub. Soc., 

 1886, p. 437.) Pallide ferruginea, griseo-vestita, antennis pedi- 

 busque cum tarsis concoloribus ; prothorace sat profunde trans ver- 

 sim ruguloso. 



Long., 13mm. 



Mas. Prosterno fere undique profunde arguteque punctato. 



This species, of which I am acquainted with only a single male, 

 is very distinct, though looking at first sight like a small M. hirta. 

 The prosternal structure and sculpture is, however, markedly dif- 

 ferent ; in the male sex of M. humilis and of M. hirta the proster- 

 num in front of the coxae is divided by a transverse depression into 

 two parts, the anterior of which is polished, and the posterior tra- 

 versed by some obsolete wrinkles, the sides of the prothorax being 

 punctate ; in the present species the anterior part is very much re- 

 duced in size, and the posterior part is entirely covered, like the 

 sides of the thorax, by a coarse deep punctuation. The supple- 

 mentary concealed anal segment is very different in its form from 

 that of the two species mentioned, the dorsal plate being broad and 

 short, gently rounded behind, not emarginate in the middle. As 

 other characters, it may be mentioned that the thoracic rugae are not 

 so deep and regular as in the other species of this group, that the 

 sides of the thorax are rounded, and that the legs, including the 

 tarsi, are entirely pale.
