HIMALAYAS AND OF INDIA. xlv 
BEMBIDIIDZ ano TRECHID. 
Of the former family, several genera will no doubt eventually be found in Nepal: a single species of 
Tachys is the only example I am able to record at present. Of the latter, Stenolophus, Acupalpus and 
Tetragonoderus have occurred: the last of which may take the place of Bembidium. 
DY TICIDA: 
Aquatic Coleoptera are apparently not much influenced by climate: the temperature of water not 
varying like that of the earth or air, is the reason we meet with the self-same species in the interior of 
India and the south of France. Dyticus appears confined to Northern Europe or America, while 
Cybister is dispersed throughout the world. Eunectes and Hydaitcus belong to Nepal and India, and 
to the latter country we may add also the following genera, viz. Colymbetes, Laccophilus, Noterus, 
Hyphydrus and Hydroporus. a 
at 
GYRINIDA. 7 
Many gigantic species of Gyrinide abound in India. Dineutus nepalensis, politus, and spinosus, 
have been found within the Himalayan districts. 
HYDROPHILID. 
Several genera of this family are as widely distributed as the Dyticide ; and most of those found in 
India inhabit Nepal. : 
NECROPHAGA. - 
Differing with most entomologists, I am inclined to believe that the carrion feeders abound more in 
warm countries than is generally believed. The religious prejudices of the Indians not allowing them 
to touch a dead ‘body, may account for the few species which have hitherto reached Europe from the 
East. Necrophorus, Necrodes, Silpha, and Oiceoptoma, are met with in India and Nepal. It is 
probable that Necrophorus is more igi adapted to Northern climates, _— the remaining genera 
affect those of tropical regions. 
EROTYLID. 
Passing Nitidulids, which have been captured in India, we arrive at Engidz and Erotylide. In the 
former family, we find Triplax, Ips, and Dacne; in the latter, Erotylus; and next to this group, 
Languiria and Eumorphus should be placed ; genera abounding in species in Nepal and India. 
DERMESTIDE. | 
In General Hardwicke’s Collection, there is a Nepalese specimen of Dermestes, similar in every 
respect to D. lardarius of Europe : a second species is closely allied to D. vulpinus of Africa It is 
scarcely possible that either of them can have been :ported into the eu mmerce. This 
genus, and its congeners, is apparently a predominant group throughout the world. : 
BYRRHIDA. ; 
The foreign Helocerata require attentive examination, Among the drawings of the Nepal Collection, 
made purposely for General Hardwicke, two species of Anthrenus are figured: they appear novel in 
form. ? 
HISTERIDA. — 
‘This family abounds in India. I am acquainted with more than fifty ewe from the Bats : some of 
the Nepalese specimens are in too mutilated a state to describe. | ; 
g LUCANIDA.
