Smvce the Linnzean Society in 1909 did me the honour to publish a previous 
enumeration of the Rhynchota of the Seychelles Islands*, based on the collections made 
by Prof. Gardiner during the first expedition to those islands, a second zoological visit 
under the same leadership has been concluded. Mr Hugh Scott, a member of the 
expedition, who remained in the Seychelles for eight months and devoted himself to 
entomological research, has made important collections, especially in the Order with which 
I have had the pleasure of acquiring some familiarity. I am now enabled in the suborder 
Heteroptera alone to enumerate 139 species, of which no fewer than 73 have been 
regarded as nondescript, while 16 new genera have been proposed. 
The distributional affinities of these insects are of intense interest. Many migrants 
have arrived and remained with their specific characters unmodified; many genera 
hitherto regarded as Neotropical and Oriental in character claim constituents in this 
fauna; Aithiopian and Palearctic relationships are pronounced. A more detailed analysis 
is deferred to the second portion of this contribution, enumerating the members of the 
suborder Homoptera, when the whole of the Rhynchotal aflinities will be detailed; this 
will also include a few species previously recorded but not contained in the present 
collections. Meanwhile some notes have been added to the Family divisions. 
I have affixed an asterisk to the numbers of those species which have been recorded 
previously, and to these I have only added the new localities and not repeated the whole 
geographical distribution. 
Order RHYNCHOTA. 
Suborder HETEROPTERA. 
Family Pentatomide. 
In the previous enumeration of this Family from the Seychelles (Trans. Linn. Soc. 
Lond., 1909), I could only record 7 species, which with one listed elsewhere brought the 
number to 8 only. This collection comprises 19 species and only misses one (Mahea 
sexualis) described in my previous contribution. The number of Pentatomidze found in 
the Seychelles up to this record therefore includes 20 species.
