Cylas turcipennis Boh., in Schénh., Gen. Cure., i. p. 369 ; Perkins, Fauna Hawaiiensis, 
il. p. 131 (1900). . 
Loc. Seychelles: Mahé, Praslin. Known from Madagascar, India, Burma, Java, 
Philippines, Bouru, Hawaiian Islands (Oahu and Maui), China, N. Australia, Southern 
United States, Antilles, Guiana. The type of C. formicarius was from Tranquebar, that 
of C. turcipennis from Java. In the Seychelles, a specimen was found in Mahé in 1905 ; 
several were found on sweet-potatoes on Cascade Estate, about 800 feet, im 1909; others 
from various low-country localities in Mahé, 1908—9; one from the cultivated islet, 
Anonyme Island, near Mahé, 1909; and one from Cotes d'Or Estate, Praslin, XI. 1908. 
Group Antliarrhina. 
MICROPLATYMERUS, h. gen. 
Rostrum short, stout, conical, convex, the antennze inserted low down near the base, 
the scrobes short, shallow, curved, reaching the lower margin of the eyes; eyes large, oval, 
transverse, lateral, not prominent, placed at the base of the rostrum, the head constricted 
behind them, polished, globose; mandibles small, scarcely visible; antennee (fig. 37 6) 
geniculate, short, the scape stout, reaching the posterior margin of the eyes, the funiculus 
with five closely articulated joints, 3—5 strongly transverse, the club small, oblong-ovate, 
shining, feebly annulate; prothorax greatly developed, rounded-trapezoidal ; scutellum 
very small, transverse ; elytra oblong, comparatively short, somewhat obliquely cut off at 
the base, covering the pygidium, the humeri subrectangular ; coxze very widely separated, 
the anterior pair distant from the base of the prosternum, small, deeply inserted ; pro-, 
meso-, and metasternum on the same plane, the last two fused; mesothoracic epimera 
large, ascending, but not impinging on the humeri; metathoracic episterna rather broad, 
polished, fused with the sternum; ventral segments 1 and 2 connate, 3 and 4 extremely 
short, the sutures 1 and 2 subarcuate, the others straight; legs short ; femora very stout, 
clavate, compressed ; tibiee short, subtriangular, unarmed at the tip, angulate at the outer 
apical angle, rounded within, the anterior pair (fig. 37 c) narrowly produced at the mner 
apical angle ; tarsi with joints 1 and 2 small, 3 strongly bilobed and clothed with long 
hairs beneath, 4 as long as 1—3 united, the claws long and divergent; body oblong-oval, 
depressed, polished, winged. 
Type, M. lodoiceworus. 
The minute insect from which the above-mentioned characters are taken is related to 
the 8. African genus Platymerus, from which it differs in having the antennz geniculate, 
with a short, closely-articulated, 5-jointed funiculus, and a small oblong club, and the 
anterior coxee small and very widely separated. Microplatymerus has the general facies 
of a small Calandrid, and the broad flattened sterna and ascending mesothoracic epimera 
are suggestive of certain Madarides of the group Barina. No external sexual characters 
have been detected. Platymerus and Antharrhinus live on African Cycads, the present 
genus on Lodoicea, the Coco-de-mer palm.
