406 PERCY SLADEN TRUST EXPEDITION 
Type, #. terreus. 
The insect forming the type of this genus has the general appearance of such 
aberrant Cryptorrhynchids as Hybomorphus and Ocladius, but it is in reality related to 
Cycloteres. The regularly rotundate shape is suggestive of the Tenebrionid genus Hrodius. 
The anterior portion of the prosternum is extremely short, thus allowing the rostrum to 
rest on the anterior coxze in repose. Achynius, Fairm., from Madagascar, may be an 
allied form. 
12. Hucycloteres terreus, n. sp. (Pl. 22, figs. 10, 10 a.) 
Very broad, rotundate-ovate, opaque, black, the antennze and tarsi rufo-piceous ; the 
entire surface covered with minute brown or reddish-brown scales and also minutely 
setulose, the legs and antennze with more conspicuous sete. Rostrum bare at the tip, . 
when denuded of scales shining, closely, finely punctate, and 4-carinate from the base 
to near the apex. Head, prothorax, and elytra densely, extremely minutely punctulate, 
the prothorax with intermixed scattered moderately coarse punctures. The elytra with 
regular rows of foveze placed in shallow striz, the interstices broad and very sparsely, 
obsoletely granulate. Beneath coarsely punctate. 
Length (exclud, head) 5—63?, breadth 33—51 mm. 
Loc. Seychelles: Silhouette, Mahé, Praslin. 
Six examples, sex not ascertained. In Silhouette this species was found in the forest 
above Mare aux Cochons, IX. 1908: in Praslin, in the ‘‘ Coco-de-mer” forest in the Vallée 
de Mai, Cotes d’Or Estate, XI. 1908: in Mahé, in the Mare aux Cochons district, ca. 1500 
feet, I.— II. 1909. 
GONOTRACHELUS, n. gen. 
Rostrum very stout, curved, as long as the prothorax, the apical portion slightly 
widened and parallel-sided, the antennze inserted beyond the middle, the scrobes deep and 
obliquely descending to the lower surface ; head globose, constricted behind the eyes, the 
latter small, superior, coarsely facetted, and placed at the base of the rostrum; antennze 
(fig. 11) with a short 5-jointed funiculus and a small, ovate, pubescent club; prothorax 
subquadrate, sharply carinate; scutellum wanting; elytra broad, oval, produced at the 
apex; anterior coxee contiguous; posterior coxee very widely separated, the intercoxal 
process truncate in front; metasternum short, the episterna covered by the elytra ; 
ventral segments 1 and 2 long, connate at the middle, 3 and 4 short, together as long as 5, 
the first suture sinuate and the others straight; tibie sinuate within, armed with a 
slender claw at the outer apical angle; tarsi very short, spongy-pubescent beneath, 
joint 3 bilobed, the claws minute, free; body oblong, convex, subglabrous, apterous. 
Type, G. quinquecarimatus. 
The insect from Long Island, Mahé, from which the above characters are taken may 
be described as a Gononotus (Lec.) with the antennal structure, 7.e. a 5-jointed funiculus, 
of Dryotribus Horn ( = Thalattodora, Perkins). Both these genera have been referred to 
Cossonina, but Gonotrachelus (and Gononotus also) seems to me to be better placed
