Pycanurn rubens , Fab. 
Cimex rubens, Fab. Ent. Sjst. iv. p. 107 (1794j. 
In tliis collection all the representatives of this species are 
of a uniform ochreous colour above. 
Aspongopus brunneus , Thunb. 
Cimex brunneus, Thunb. Diss. Ent. Nov. Ins. Spec. ii. p. 45 (1783). 
This species is closely allied to and commonly confounded 
with Cimex obscurus , Fab. The two species, however, seem 
to be thus easily differentiated:— 
Abdomen above red. 
Third joint of antennae a little longer than second, brunneus, Thunb. 
Abdomen above black. 
Second and third joints of antennae equal . obscurus, Fab. 
Aspongopus ochreus , Hope. 
Aspongopus ochreus, Hope, Cat. i. p. 25 (1837). 
The first four joints of antennae are black; they are de¬ 
scribed (l. c.) in error as 11 fuscis.” I have examined the type 
with Prof. Westwood. 
Macrina dilatata , n. sp. 
Broad, ovate. Rufous. Head broad, triangular, mode¬ 
rately covered with deep dark punctures; lateral lobes slightly 
sinuated, divided at apex, meeting beyond central lobe, which 
is much shorter. Antennae with the third joint shortest; 
fourth rather longer, fifth longest, black, with the base rufous 
(the first four joints vary in different specimens from rufous to 
luteous). Rostrum reaching anterior coxae. Pronotum with 
the base slightly rugulose, somewhat crescent-shaped in front, 
■where it is bordered with a pale luteous band between the 
lateral angles, which are produced iuto two stout spines 
directed forwards ; spinal apices black. Anterior portion of 
the pronotum abruptly deflexed to head, transversely costate, 
moderately punctured with brown; lateral borders denticu¬ 
lated. Scutellum reaching beyond base of membrane, with 
five longitudinal, indistinct, somewhat catenulate elevated 
ridges, which are sprinkled with luteous, the centre ridge 
generally most indistinct. Membrane pale fuscous, extending 
beyond apex of abdomen. Underside of body and legs con- 
colorous, thickly and finely punctured with brown. Tibite 
sulcated. 
d , long. 16 millims., lat. at base of corium 8 millims., exp. 
pronot. ang. 11 millims.; ? , long. 17 millims., lat. at base of 
corium 8^ millims., exp. pronot. ang. 12 millims.
