150 Mr. H. W. Bates on the Longicarn Coleoptera 
Thorax even on the surface ; lateral spines short, conical, placed 
near to or distant from the hind angles. LElytra free from tu- 
bercles, centro-basal ridges, and lateral carine, rarely having 
faint dorsal carine, truncated at the apex. Legs moderate; 
thighs clavate ; tarsi with the basal joint scarcely longer than 
the two following taken together. 
d Apical dorsal plate of the abdomen entire or sinuated at 
the tip, ventral notched. 
 Ovipositor elongated beyond apex of elytra; apical dorsal 
plate pointed or obtuse, ventral truncated or (rarely) famtly 
notched at the tip. 
1. Nyssodrys sedata, un. sp. 
N. oblongo-ovata, convexiuscula : thoracis spinis lateralibus conicis, 
acutis, prope angulos posticos sitis: elytris sordide fulvis, punctis 
plagisque brunneis, ante medium plaga communi transversa ob- 
scure ceeruleo-grisea, pone medium fascia obliqua cana: femoribus 
crassis. Long. 47 lin. ¢. (3 exempl.) 
Head ashy brown. Antenne dull reddish, with brown pile ; 
tips of joints, from the third, black. Thorax widening from the 
front to the tips of the lateral spines, which are conical and 
placed near the hind angles, thence narrowed in an oblique line 
to the base; surface dark brown, with tawny marks, four small 
tawny spots being arranged in a quadrangle in the middle. 
Elytra subovate, convex, apex briefly and obliquely truncated ; 
surface punctured, tawny brown, with a number of small spots 
and several larger patches dark brown ; across the suture before 
the middle is a transverse bluish-grey patch, and behind the 
middle on each elytron is a broadish, oblique, hoary-white fascia, 
beginning on the lateral margin, but not reaching the suture. 
Body beneath and legs ashy brown ; thighs thickly clubbed. 
6 Terminal dorsal plate of the abdomen obtuse; ventral 
deeply notched. 
This was a rather common insect at Ega, on dead boughs in 
the forest. 
2. Nyssodrys lentiginosa, u. sp. 
N. oblongo-ovata, convexiuscula: thoracis spinis lateralibus conicis, 
prope angulos posticos sitis: elytris brunneis, disco cezeruleo- 
griseis brunneo maculatis, utrinque plagis irregularibus fulvis | 
plerisque subsuturalibus, una majore laterali: femoribus modice — 
clavatis. Long. 33-4 lin. 2. (3 exempl.)
