MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 401 
Genus HAPTONCUS (4z70c, which touches; and oyxoc (for the sake of euphony, ovxoc), 
tumidity, referring to the large last article of the labial palpi). 
Oculi modici, basin capitis attingentes. Labrum bilobum.  Epistoma prominens. Paraglossz alis mem- 
branaceis plicatis. Palpi labiales articulo ultimo magno, calyciformi. Abdomen articulis duobus 
expositis, sed interdum sub elytris contractis ; articulo primo et ultimo majoribus ; caeteris zequalibus ;. 
fimbriis haud apparentibus. ; | 
Body small, slightly convex. Head rather large; epistome projecting; eyes moderate 
in size, oceupying the whole of the sides of the head. Antennal grooves short and con- 
verging. Antenne with the first joint large and swollen, the second short, convex, the 
third to the eighth inclusive very slender, the third longer than any two of the rest, 
which are nearly of equal length, the seventh and eighth gradually a little wider, the 
ninth, tenth, and eleventh forming a large oval club, very pubescent. Labrum deeply 
bilobed. Mandibles strongly bidentate, the second tooth not much behind the first, 
ciliated on the inner side. Maxillary lobes moderate, bearded at the point and on the 
inner side. Maxillary palpi with the first article small, the second swollen at the apex, 
the third short and stout, and the last article long and cylindrical. Labial palpi with the 
last article large, cup-shaped, the preceding article small and likewise cup-shaped, holding 
the last. Ligula very small, with large, projecting, ear-shaped membranaceous para- 
glossze, which appear to be composed of a double fold with ciliated margins. Mentum 
deeply emarginate. Thorax slightly convex, transverse, margined. Scutellum moderate. 
Elytra not striate; apex of each elytron obliquely truncate. Abdomen scarcely visible 
from above, but looked at from behind, the pygidium and penultimate segment are 
visible; no fimbrize are visible, the suture of the dorsal and ventral segment being on 
the margin; below, the first and last segments are the longest, the rest about equal, the 
penultimate being slightly the longest. Prosternum projecting, but not prominent, resting 
on the metasternum. Metathorax without axillary pieces. Posterior coxe placed most 
apart. Legs robust; thighs with a groove to receive the tibiæ. Tarsi slender, not 
dilated. 
This genus forms a transition between Carpophilus and Epurea, and it is doubtful 
whether it properly belongs to the Carpophilide or to the Nitiduline. The former has 
atleast two segments of the abdomen exposed, the latter only one. In this genus the 
dorsal segments of the abdomen are often so curved-in that they are not visible; but 
when looked at from behind, the last two are seen. I have therefore placed it near the 
end of this group.
