thorax. The antenne are yellow, but the broad and abrupt three-jointed club is dark. 
The yellow legs are extremely slender and rather long. Four specimens. 
Compared with the European #. gyrinoides, Marsh., this is a very distinct species, 
the form being rather broader and flatter, the legs more slender, and the club of the 
antenne black. I have not seen EL. apicalis, Lec., the North-American species of 
the genus, but it has the elytra red behind and the antenne entirely yellow. 
Subfam. BIPHYLLINA. 
This subfamily has consisted up to the present time of about a dozen species; the 
large series of forms found in our region is therefore remarkable and unexpected. 
The position of these insects has been the subject of prolonged difference of opinion. 
I here follow Dr. Ganglbauer in placing them with the Cryptophagide, as they have 
but little affinity with Mycetophagide. ‘The Biphylline are specially characterized by 
the structure of the feet, which are 5-jointed, the third joint being furnished at the 
tip with a free membranous appendage. They are singularly uniform in the structure 
of the sternal pieces, and the generic characters are to be found in the details of 
structure of the antenne and feet, and in the peculiar lines and impressions found on 
the metasternum and abdomen. 
The group is probably richer than is at present believed, as I possess undescribed 
forms from Borneo and Australia. 
GONICCELUS, gen. nov. 
Metasternum utrinque linea post-coxali profunde impressa, elongata, posterius longius ducta. 
I place in this genus a considerable number and variety of forms closely allied to 
Diplocelus, but agreeing in the possession of very strongly marked elongate lines 
behind the middle cox. This is the only character I can detect common to all the 
species and at the same time foreign to Diplocelus. ‘The club of the antenna is always 
3-jointed, and exhibits in no case any tendency to approach that of Biphyllus. The 
pair of lines between the hind coxe is present in a highly developed form, as in all 
the Biphyllinz I have seen ; but there is no trace of the line behind the coxa going 
to the outer margin of the abdomen, and this distinguishes Gonicelus from several 
others of the subfamily. 
The first division of the genus includes several remarkable forms in which the 
head or the thorax, or both, is armed with projections or horns. I have long had 
in my collection a specimen of this kind and had not suspected its close affinity with 
Diplocelus, but the long series of species brought together by our Editors places the 
position of these forms beyond doubt. 
I divide the species of Gonicelus into three groups, the third of which contains 
numerous small and obscure forms very closely allied, but in some cases with peculiar
