DISTANT—RHYNCHOTA. PART I: SUBORDER HETEROPTERA 175 
103. Megacelum (Creontiades) mimicum, sp. n. (Plate 18, fig. 15). 
Head ochraceous; pronotum pale testaceous with darker speckles, and with a black 
subbasal marginal line; scutellum pale testaceous, the basal area speckled with black and 
with the apex black and subnodulose; corium ochraceous; cuneus ochraceous, a black 
spot at inner angle and the posterior margin more or less sanguineous; membrane 
ochraceous, the cellular margins sanguineous; body beneath (imperfectly seen in carded 
type) pale testaceous; legs ochraceous, posterior femora (excluding basal areas) castaneous; 
antennze ochraceous, first joint a little thickened and about as long as pronotum and 
sparingly, shortly hirsute, second joint about twice as long as first, slightly curved, third 
a little shorter than second, fourth less than half the length. of the third ; head moderately 
and obliquely deflexed before eyes, and with a distinct narrow central longitudinal 
sulcation ; pronotum with the anterior margin about half the width of the posterior ; 
seutellum with the disk somewhat longitudinally raised; tibize distinctly spinulose ; 
corium distinctly pilose. 
Long. 74 mm. 
Loc. Seychelles. Silhouette: Mare aux Cochons, over 1000 feet; near Mont Pot- 
d-eau, 1500 feet; also cultivated country near coast. Mahé: near Morne Blanc, about 
1000 feet; Morne Seychellois, ca. 1500—2000 feet; Long Island. Praslin; Cotes d’Or 
Estate. Bird and Dennis Islands (Fryer). 
Allied to M. rubrinerve Stal, from Central America, but structurally differing from 
that species by the shorter first and second joints of the antenne, different colour 
markings &c. For M. rubrinerve Stal, I had (1883) founded a genus (Creontiades), but 
subsequently (1904) considered it as only a sectional division of Megacalum. Poppius 
however is now using Creontiades as a distinct genus. 
104*. Collaria improvisa, Reut. 
Collaria improvisa Reut., Rev. d’Ent., xi. p. 208 (1893). 
Loc. Seychelles. Silhouette; near Mont Pot-a-eau, 1500 feet ; Mare aux Cochons, 
over 1000 feet. Mahé: from near Morne Blanc, under and over 1000 feet; Cascade 
Estate and forest above ; also places in the low country. 
Swept from grass &c. ; characteristic of more open places and clearings in lower part 
of mountain-forests (H. Scott). Also (teste Poppius) found in Madagascar, Kilimandjaro 
and 8. Africa. 
The genus Collaria was till recently regarded as a neotropical and nearctic one, and 
its presence in the Seychelles is probably due to accidental introduction. Poppius 
however has recently described a species collected during Sjéstedt’s “ Kilimandjaro-Meru 
Exp.” 
105. Aretas sanguinarius, sp. n. (Plate 18, fig. 12). 
Ochraceous ; eyes black ; apex of head, lateral margins of pronotum, about basal half 
of corium posteriorly oblique, apex of clavus, posterior margin of cuneus, and cellular 
margins to membrane, sanguineous; body beneath and legs ochraceous; antennze with 
23—2
