382 Suarp—On New Zealand Coleoptera. 
The insect for which I establish this genus is not all closely allied to any other 
European or exotic form known to me. It has the aspect of a Batrisus, but in 
Reitter’s arrangement of the family would apparently be placed in the Pselaphini. 
The first ventral segment behind the coxe is quite short, and is strongly carinate- 
elevate between the coxz which are approximate, the following segments are 
short, the second being, however, as long as the third and fourth together, the 
fifth short and transverse, the sixth in the male (from which this description is 
taken) is large at the side, but in the middle is cut away nearly to the base. The 
first visible dorsal segment is rather short, but longer than the second; this, 
as well as the third and fourth, are subequal, the apex much deflexed, the two or 
three basal segments obscurely margined at the sides, with greater inequality in 
the lengths of the segments. The palpi are similar to those of Batrisus. The 
front cox are exserted, and rather elongate. The tarsi consisting apparently of 
two elongate joints, but there is also really a minute basal joint; the single claw 
is elongate. 
The genus in the New Zealand list should be placed before Dalma, from which 
it is distinguished by the shorter hind body, and the produced front of the head. 
In the Verh. Ver. Brunn, xx. p. 197, Reitter has briefly indicated a New 
Zealand genus which he calls Adalmus (hitherto without described species), but 
which, from the brief characters given, evidently cannot be the present genus. 
Dalmisus batrisodes, n. s.p.—Subgracilis, rufus, tenuiter pubescens, antennis 
pedibusque gracilibus; prothorace elongato, tricanaliculato, canaliculis ad basin 
foveolatis, impressione basale transverso profundo. Elytris elongatis, basi intra 
humeros profunde impresso. Long. 21 m.m. 
Antennz with the basal joint thicker than those following, and about as long 
as the second, third, and fourth together; the three terminal joints slender, though 
stouter than the others. Head with small eyes, which are prominent only in 
front; in front of them a good deal produced, the genz delicately, but elongately 
setose. Thorax as long as broad, much narrowed in front and behind. Elytra 
without punctuation, but with a sutural stria, and a large deep intra-humeral im- 
pression. ‘The male has a very small spine on the intermediate trochanters. 
This species was sent me from Greymouth by Mr. Helms some time ago. 
Though it is probably known to Herr Reitter, as Mr. Helms has been in the 
habit of transmitting his Pselaphidz to him, it does not appear to have been 
yet described.
