segments compressed and somewhat grooved lougitndiually nearly as in Pbjfho- 

 (leres depressiis Jekel (I'Soo), segments 7 to 'J thin, 8 and 9 each about as long 

 as 2 to 4 together, 10 and 11 short. 



Prothorax as in Pti/choderes mixtus, but wider and the sides more rounded, 

 anteriorly with conspicnous black spots. ' 



Elytra also as in P. mixtus, the seriated punctnres less numerous and the 

 apical callosity vestigial. 



Underside grey, almost white, jn-othorax with a black stripe below the lateral 

 carina and the tibiae with two black spots, one near the base and the other in 

 the middle ; process of mesosternum widest at the apex, which is rounded ; anal 

 stcrnite truucate-sinuate. 



Length (exclusive of head) 2-") mm. 



One cJ from Manuos, Amazons. 



3. Mecotropis duplicatus spec. nov. 



(?. Nearest to M. crassicollis Jord. (Is9.5), bearing a pilose, round, central 

 spot on the metasternum. Slenderer than crassicoUis. The uppersidc densely 

 variegated with grey, the markings being diffuse. Rostrum somewhat narrower 

 than in crassicoUis, on underside with two deep grooves behind the false 

 mentnm. 



Prothorax less rounded at sides than in crassicoUis, but more so than in 

 cinerasceiis Jord. (1808), somewhat longer than broad, rather deeply impressed 

 mesially at the carina, the prominent central tubercle of crassicoUis very feebly 

 indicated. 



Scutellam rouuded-triangalar. Elytra as short as in crassicoUis ; the groove 

 bounding the raised basal margin not continued to the shoulders ; in posterior 

 half each interspace with an additional row of punctures, with the exception of the 

 sntural and lateral stripes. 



Prosternite slightly impressed in front of the coxae, uot grooved as in 

 crassicoUis. Mesosternal process ronnded-triangular, narrower than in crassicoUis ; 

 last abdominal sternite rounded, with a very faint indication of a small central 

 sinus. 



Femora aud tibiae sparsely pubescent grey, without markings ; tarsi black, 

 first and fourth segment densely pubescent grey with the exception of their apices, 

 first hindtarsal segment less than twice the length of fourth, second as long as

4. Mecotropis annulipes spec, nov, 



(^ ? . In structure hardly distinguishable from M. cinerasceiis Jord. (1808), but 

 the coloration of the legs constanlly ditt'ereut. In cinerasceiis tlie tibiae bear 

 each a broad clayish ring at the base and another narrower one near the apex, 

 and the tarsi have a ring of the same colour near the apex of the first segment 

 and a broader one on the claw-segment. In annidipes, on the other hand, the 

 fore- and midtibiae are more diffusely grey, the first tarsal segment bears a grey 

 ring at or near the base, the second segment is grey with the exception of the 

 apex, and the claw segment is (jnite black.
