40 Rev. F. D. Morice on male hrminal segments and 



exceedingly long cheeks, sparsely punctured, shining ab- 

 domen, and narrowish white fasciae (especially those 

 towards the apex). The sculpture of the propodeum is 

 also somewhat peculiar : its base is occupied by clathrate 

 rugosities, or rows of adjacent fovea;, which gradually 

 diminish, and become vaguer as they approach the narrow 

 shining triangle at its apex. 



I know the species only from the Canaries, etc. (the 

 region from which came also Brulle's types). 



(In the % the genae are not particularly long, less so 

 decidedly than their greatest breadth. In the $ they looh 

 even longer than they are in proportion to their breadth, 

 an effect which seems to be due to their convexity, or to 

 something in the disposition of the hairs. In the arma- 

 ture figured the apices of the sagittse were unluckily 

 distorted by pressure of the cover-glass. Normally I 

 think they would look much as in the other species, 

 almost linear — being viewed in profile only.)

The name Itgatus was first employed by lUiger, who 

 however did not describe his species. Erichson's descrip- 

 tion is of a $ from Spain, and, as is usual with these early 

 descriptions, would suit equally well a number of species. 

 Following Prof. Perez, I adopt the name for a species of 

 which I have dissected three or four ;^ $ from various 

 Mediterranean districts (that figured is from Barcelona, 

 and Erichson's description is fairly suitable for it, though 

 inadequate). 



The $ has a strong external character in the well- 

 marked dense tufts, in some lights looking almost velvety, 

 which adorn the lateral angles of the last visible ventral 

 segment. It is finely and rather sparsely punctured witii 

 shining interspaces. 



This species, and the four which follow, agree with the 

 last five in having the stipes unnotched, but differ from 

 them in having the lobes of the seventh ventral plate much 

 more transverse, and developed more abruptly, so that one 

 may distinguish in them a basal as well as a lateral ex- 

 terior margin (they might be called c^nadrilatercd , the 

 others being trilateral). But what is still more conspicuous 

 is that they spring not from elongate " petioles," but from 

 comparatively broad and stumpy " trunks." (The condition
