Another new beetle exhibited by Mr. Barker was Apthonia atratula. 
" This insect appears to be allied to A. herbigrada, but is black with a trans- 
verse thorax which is also more finely punctured." 
Mr. Barton exhibited fine species of Carenum, from Victoria, and 
remarked upon the difficulty of dividing species by the punctures upon the 
elytra — a mode of multiplying species very prevalent at present— and 
instanced one species exhibited, Carenum marginatum, some with the ely- 
tra perfectly smooth, and others deeply punctate-striate ; these by some 
had been divided into species, but having seen specimens run gradually 
from deeply punctate-striate to perfectly smooth individuals, he had 
but little doubt that they were one and the same species. 
C. Spencii and C. tenitilatum. These species were rare, and the very 
few examples captured were not sufficient to ascertain whether they varied 
in the same manner as C. marginatum. 
Mr. Barton also exhibited four specimens of Bolbocerus mobilicornis, 
and two of Bolbocerus testaceus, an insect which he thought would prove 
a variety of B. mobilicornis, and drew attention to the great variation in 
size of the insects exhibited, also remarking that the time would soon arrive 
when this rare species might be taken, if a little time and labour were spent 
in looking after it. Mr. Barton's specimens were taken in the neighbour- 
hood of Baptist Mills and the Boiling Wells. 
Mr. George Harding, the Hon. Sec. of the Section, then read a short 
paper upon the Dupanulae. The Dupanulse were a smaller order of moths, 
commonly known by the popular term of " hooktips," from the hooked 
form of the upper wing ; they had a great resemblance to the Geometree 
in the perfect state. Larva of the whole of the species smooth, with 
fourteen legs, and pro-legs wanting ; pupa enclosed in a cocoon. Imago, 
antennae of male pectinated ; female generally filiform, abdomen slender 
in both sexes, wings comparatively broad, generally hooked at the tip. All 
the species, with perhaps one exception, appeared to be double-brooded. 
One species — Unguicula — flew commonly in the day-time in the beech 
wood at Stapleton, and two others — Hamula and Facula — might occasion- 
ally be seen flying by day. The author, after remarking that the Bristol 
district was the only one in the kingdom in which the whole of this family 
might be taken, took each species separately, and after describing the diffe- 
rent larvse and food plants, entered into abundant detail as to how, when, 
and where each species might be captured, and mentioned the uncertain 
appearance of some species of this group. Thus Unguicula might be 
found in great abundance during some years, while in other seasons not a 
single example could be obtained. Sicula was another species mentioned 
as of very uncertain occurrence ; this fine species was first captured in the 
kingdom in May, 1837 ; a single specimen being taken by Mr. Metford on 
the slope over the river at Leigh. This insect was unique in the Rev. H. 
Bumey's collection, to whom Mr. Metford presented it, till 1856, when two
