380 PERCY SLADEN TRUST EXPEDITION 
Genus incertz sedis. 
ScCIATROPHUS, gen. nov. (Figs. 1—5). 
Caput elongatum, depressum ; submentum valde in medio productum, maxillee lobo 
intus setis rigidis ciliato, mentum latum, ovale, antrorsum subangustatum lateribus fortiter 
rotundatis ; antennee scapo plano triangulo ; funiculo 5-articulato, hujus articulo 1° trun- 
cato pyriformi, 2° minore, sequentibus transversis, latitudine vix crescentibus, capitulo 
oblongo, acuminato, solido sed transversis pilis notato. Pronotum transversum, a prosterno 
carina seyunctum ; coxe anteriores leviter distantes, tibiee anticee versus apicem leviter dila- 
tate, apice rotundatz, extus non serrate, tarsorum articulus 3 bilobus. Scutellum parvum. 
Head flattened and broad, visible beyond the thorax from above; the labial and 
maxillary palpi three-jointed (Figs. 3, 4); labrum distinct, submentum prolonged medianly 
upwards into a long peduncle, the mentum being attached to its inner side towards the 
apex (Fig. 3); the lateral arms of the hypostoma very long; the antenne (Fig. 2) 
elbowed, with a depressed triangular scape and a funiculus of fine joints, the first truncate 
pyriform, the second rather shorter, and the remainder hardly increasing in size towards 
the club, which is narrow and cone-shaped with two transverse rows of hairs, one near the 
base and the other round the centre, the apex having a tuft of pale hairs with 2—3 
indistinct rows of hairs just below. The eyes prominent and nearly round, the antennz 
inserted below the dorsal margin of the head beneath the eyes, whilst the pronotum 
is divided from the prosternum by a ridge; the anterior coxe are placed moderately close 
together, the tibize being somewhat dilated towards the apex, and not having any serration 
on the outer edge; the tarsal joints short and the third bilobed (Fig. 5). 
1. Sciatrophus fuscus, sp. n. (Figs. 1—5). 
Oblongo-ovalis, fuscus, pubescens, thorace subquadrato sed lateribus leviter rotundatis, 
zqualiter minutissime granulato, pubescente ; elytris convexis, setosis, subtilissime lineato- 
punctatis, lateribus subparallelis, apice rotundato, interstitiis planis, punctatis piliferis. 
Long. 1°5 mm. 
Head and prothorax black, elytra varying from light brown to black, but covered 
with longish pale yellow hairs ; the head is produced anteriorly, 
minutely rugose and pubescent, with a short polished longi- 
tudinal carina in the centre over the mouth, and several rugose 
longitudinal lines on the considerably raised surface of the 
anterior margin below the eyes which are somewhat prominent 
and round, but so placed on the lateral edges of the head as to 
be raised longitudinally down the centre. The antennez 
(Fig. 2), which are geniculate, have the scape as long as the 
funiculus together with half the club, and it is basally very thin, 
but becomes somewhat abruptly widened on the outside into a 
large triangular surface ; the club is acuminate, not compressed, 
and only slightly broader than the first funicular joint, it has no 
sutures, but there are two circles of hairs, one near the base

gen. et sp. nov. 9, x 24. 
* Unfortunately the specimen figured was not in a good position. Its head is so much depressed that the 
elongation of the front is not visible, and the thorax is too much drawn away from the elytra, so that its base 
appears too curved.
