150 Mr. H. W. Bates on the Longicorn Coleoptera 



Thorax even on the surface ; lateral spines short, conical, placed 

 near to or distant from the hind angles. Elytra free from tu- 

 bercles, centro-basal ridges, and lateral carinse, rarely having 

 faint dorsal carinse, truncated at the apex. Legs moderate; 

 thighs clavate ; tarsi vi^ith the basal joint scarcely longer than 

 the two following taken together. 



6 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) faintly 

 notched at the tip. 



1. Nyssodrys sedata, n. 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 caeruleo-grisea, pone medium fascia obliqua cana : femoribus 

 crassis. Long. 4^ Un. S • (3 exempl.) 



Head ashy brown. Antennae 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. 



cJ 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, n. sp. 



N. oblongo-ovata, convexiuscula : thoracis spinis lateralibus conicis, 



prope angulos posticos sitis : elytris brunneis, disco ceeruleo- 



griseis brunneo maculatis, utrinque plagis irregularibus fulvis 



plerisque subsuturalibus, una majore lateral! : femoribus modice 



clavatis. Long. 3f-4 lin. $ . (3 exempl.) 



Head tawny or ashy brown. Antennae reddish ; tips of joints, 



from the third, black. Thorax widened from the front to the 



tips of the lateral spines, which are conical and placed obhquely 



near the hind angles, thence narrowed in an oblique line to the 



base; surface dark brown, with scant ashy pile, and marked
