shaped head, . and belongs to P. longicornis Reut. The label bears. 
the name Phytocoris rubrovulneratus, but in the text the insect was 
described as a Deraeocoris. Motschulsky’s description of the mem- 
brane is very fantastic, based as it is on an irregularly mutilated 
membrane.

Represented in the collection by three type-specimens, two of 
which are mutilated, from Mt. Patannas. The systematic place assigned 
to the genus Acratheus Dist. by its describer seems to me to be 
indubitably correct, but had Distant followed his own system, he 
should have placed it in his subfamily Mirinae. The ovate body 
combined with a vertical head extended downward much below the 
level of the sternum, the very high genae, the insertion of the four 
posterior coxae, and its general aspect clearly indicate that it belongs 
to the Halticaria. It is, however, aberrant in this division by having 
the vertex longitudinally sulcate at the base, a pronotal collar, and the 
tibiae practically without spines. The collar of the pronotum is not 
mentioned by Distant and is not indicated in his figures, but it is, 
though narrow, quite distinct, especially if viewed from before. 
In his translation of Motschulsky’s description Distant 
has omitted that also the antennae are described as whitish, and he has 
rendered the word alae by ,hemelytra“ and vix distincte by ,very (!) 
distinctly“.

The six type-specimens (from Colombo) are mostly in good 
condition, though slightly mutilated. This species is common in Ceylon, | 
judging from the numerous specimens taken in several localities by 
Uzel and Horn. 
The types of the following exotic Heteroptera described by 
Motschulsky must be regarded as lost. With one exception they 
are from Ceylon. 
Cydnus ? minutus. — Described from two localities (Colombo 
and Mt. Patannas). It is not mentioned in Distant’s Indian Fauna
