SPHHROTRYPES, NOv. gen. 
Caput oblongum, in rostellum haud productum. Oculi bipartiii. 
Antenne -lateraliter inter mandibulas et partem inferiorem 
oculorum inserts, breves, funiculo 7-articulato, articulis latitu- 
dine crescentibus, clava ovata, rotundata, compressa, 3-articulata, 
vittis setarum transversis annulata, suturis transversis. Pro- 
thorax lateraliter marginatus. Mesosternum brevissimum, inflexum;

spinose. Tarsorum articuli 1-3 equales, 30 bilobo. 
Head flattened, oblong but not rostrate; eyes bipartite, the 
divisions flat, subtriangular, granulate and widely separated, united 
posteriorly by a fine carina. Antennz inserted at upper angle of 
lower division of eye, short, their scape curved, slightly clubbed ; 
funiculus with 1st joint large, globose, 2nd obconical, 3—7 trans- 
verse, increasing in width ; club rounded oval, flat, with transverse 
sutures, Ist two joints transverse, together equal in length to 3rd, 
with transverse bands of short hairs, three on 1st joint, two on each 
succeeding joint, which give the club the appearance of being 
multi-articulate ; apex of 3rd joint spongy, covered with short thick 
serrate hairs. Mandibles stout, prominent, not toothed. Maxille 
very hairy externally, inner margin convex, set with short flat 
spines ; maxillary palpi short with joints equal in length, hairy. 
Submentum inconspicuous, produced into a short pointed process 
on either side of mentum, which is oblong, slightly narrowed at 
base and in middle of sides, with apex truncate ; ligula small, ovate 
acuminate, inserted near apex of mentum; labial palpi short, 
joints 1 and 3 as long as broad, 2 transverse, densely hairy. 
Prothorax bordered at sides, excised in front to anterior cox, 
which are widely separated by a transverse prosternal process. 
Mesosternum very short, inflexed so that anterior and middle coxa 
meet when the thorax is depressed. Metasternum barely larger 
than 1st abdominal segment, its episterna moderately wide, dilated 
anteriorly. Posterior coxee separated by a broad rounded process 
of Ist abdominal segment, which is slightly longer than the 2nd, 
3rd and 4th successively shorter, 5th about equal to Ist. Anterior 
tibie slightly dilated towards apex, outer margin almost simple 
except for a strong outwardly directed spine at apex and a smaller 
spine at inner angle; hinder tibiee slightly curved, spined exter- 
nally. Tarsi with 3rd joint bilobed, its processes long and narrow. 
In spite of the divided eyes, I think this very distinct
