16 NOTES UPON THE GENERA SITONA, &C. 



colour of the antennae ; I propose, notwithstanding the priority 

 of description, in this case to retain A. Gyllenhalii, as a tribute 

 to so eminent an Entomologist. No. 56. A. Radiolus, mas. f em. 

 No. 57, A. oxurum, {51, fern, mas.) In the second part of Mr. 

 Kirby's monograph, he has expunged A. oxurum, as merely a 

 variety of A. Radiolus. No. Q7, A. Angustatum ; this single 

 insect is A. Loti. No. 68, A. scutellare. This is a very distinct 

 species, the last described by Mr, Kirby ; it seems to be taken 

 in plenty, by Mr. Gibson, of Hebden Bridge, Yorkshire. 

 I never took but one specimen, a female ; but I possess two 

 males. There are three females of this species in the British 

 Museum, named A. Kirhi't, and placed there by the late Dr. 

 Leach, — a name, I am sure, every Entomologist will support 

 in preference to A. scutellare, out of reverence for the living and 

 the dead. A. glabratum. There is a note in the hand-writing 

 of Mr. Kirby, in his MSS. list, that induces me to think this 

 species is a variety of A. Loti. "69, N.D. A. glabratum, 

 Spence, var. Apion Loti, K." There is an insect pinned, with 

 a label, and a number 69, N.D. attached to the pin, but it is a 

 male of ^. viciw, which unfortunately increases the obscurity : 

 the original specimen appears from Mr. Stephens's illustra- 

 tions, to be in Mr. Spence's cabinet. I have not seen one in 

 London; I must, therefore, give this name in doubt. No. 71, 



N.D. A. , Kirby MSS. is A. Loti; No. 72, N.D., J. im- 



pressicolle, Kirby MSS. This is a female of A. punctigerum. 

 No. 73, N. D., A. Iceviusculum, Kirby MSS. This a fine 

 male specimen of the same. No. 74, A.dissimile, Kirby MSS. 

 This is an ^. Icemcolle, mas. 



A. Curtisii. This insect is in the cabinet of Mr. Curtis : at 

 first sight it has the habit of the female of A. puhescens ; but, 

 upon a closer examination, it sometimes differs : the rostrum 

 of the former is rather shorter and stouter ; the antennae in A. 

 puhescens are black ; in A. Curtisii, piceous, with the club 

 black, and placed a little nearer to the base of the rostrum. 

 A. puhescens is deeply impressed between the eyes, and ob- 

 scurely striated. A. Curtisii is very indistinctly impressed 

 between the eyes, and delicately striated;'' in other respects, 



^ These differences in the sculpture are seen more or less distinctly with a 

 powerful lens. I use a Coddington for minute insects, it defines so well ; but 

 without care there is danger of mutilating the insect, on account of its short 

 focus.
