an acute conical spine jnst behind miikllc, and bcfure tkis spine a prominent 

 callosity. Elytra islightly widening behind, obliquely rounded at apex, sutural 

 angle not produced into a spine ; seven costae on each, the first close to suture, 

 but curving away from it at basal fourth. Prothorax beneath granulose at sides, 

 plicated and sparsely granulated mesially : intercoxal process arched, narrow, 

 reaching nearly to liinder side of coxae. Mesosternum granulose in middle ; 

 intercoxal process about half the width of the coxa. Metasternum rough with 

 transverse granules, except the episternnm, which is nearly smooth. 



Length, 15 mm. ; elytra, 11 mm.; breadth, 4 mm. 



Hab. Benito, French Congo.

The long thorax bearing a rounded tubercle in front of the side-s])ine, the 

 longer prosternal process and the broader mesosternal one, as well as the non- 

 dentate apex of the elytra, distinguish this sjiecies abundantly from viridescrns. 



We received this species, and all the others from Benito as well as Batanga, 

 from Monsieur H. Uonckier, Paris. 



2. Saphanidus dubius spec. nov. 



(?. A connecting link between Saphanidus and Allogaster. Underside of 

 body, front of head, antenna and legs dark rufous brown ; occiput, pronotum and 

 elytra metallic green-blue, not strongly glossy. Head densely punctured ; upper 

 lobes of eyes nearly as widely distant from one another as in Allogaster geniculata. 

 Antenna only as long as the body ; scape very densely rugate-punctate ; third 

 segment twice the length of fourth, tiiis a very little longer than fifth, eighth 

 to tenth snbdentate. Prothorax with obtuse lateral tubercle as in Allogaster 

 geniculata, subnodose above, very densely jjunctured, a small smooth mesial space 

 behind middle. Scntellum pitchy black, rounded. Elytra rounded together at 

 apex, not sjiiiied at sutural angle, costate, with the tirt-t, third and fifth costae alone 

 rathi-r prominent, densely and coarsely jnmctate from base to apex. Prosteruum 

 transversely plicate and punctured ; intercoxal process triangular, reaching close 

 to tlio mesosternum without touching it. Mesosternal process also triangular. 

 Abdominal segments 1 to 4 with a woolly patch each, ■^ truncate, 6 sinuate. Legs 

 densely and rugosely pnncturod. 



Length, 15 mm. ; elytra, 11 mm. ; breadth, 4i ram. 



Hab. Batanga, ('araeroons.

3. Saphanidus fulvus spec. nov. 



?. Tawny, clothed with a clayish yellowish pubescence; antenna, femora and 

 ab.lomen luteous, extreme tip-> of femora and upperside? of tibiae blackish. 



Front of head punctured, occiput rugate-granulate. Eye as large as in 

 viridexcens. Scape of antenna paler than the other segments, and less pubescent. 

 Prothorax flattened and rounded as in riridescens, a little longer than in that 

 species, with a minute lateral tubercle, minutely granulose all over. Elytra very 

 densely and minutely inmctured all over, slightly rugose at apex, with faint traces 

 of two discal carinae ; apex of each elytrnm obliquely rounded. Both the pro- 

 and midcoxae contiguous, the intercoxal processes very short, obtusely triangular. 

 Prosteruum transversely wrinkled ; metasternum densely punctate-granulate at
