abrupt, rapid, and by no means graceful ; and it does not appear to 

 bave tbe power of controlling itself wben on tbc wing, for I bave often 

 seen it fly in an insane manner against tbe trunk of a tree, a brancb, 

 or any otber object tbat may be in its line of fligbt ; and wben it bas 

 performed its journey without any accident, it aligbts abruptly and 

 awkwardly. As a rule, bowever, it does not attempt to fly to any 

 great distance at a time. 



Difference of temperature affects tbem considerably, for in bot 

 sultry weatber tbey were most vociferous, wbereas wben it w^as (com- 

 paratively speaking) cool and breezy tbey were abnost silent. I did 

 not observe any of tbe females in tbe act of oviposition.

 OF NEW SPECIES (No. 19). 



BY H. W. BATES, P.L.S., <&c. 



ScAEiTES (B[aplotrachelus) POLTPLEUEUS, sp. n. 



Latus, oblong o-ovatus, viodice convexus, niger, suh-opacus ; ihorace 

 hawfo, laterihus utrinque bashi versus paid ul urn siniiatis; elyfris ovatis, 

 iitrinque costis 8 Icdvihus (octava marginali acuiissima) interstitiis 

 granuJatis, striato-pv/nctulatis. Long. 17 lin. 



Ratber more ovate in form tban H. 7ioIcop7eurus and patruelis, 

 and differing conspicuously in tbe sculpture of tbe elytra. On eacli 

 elytron tbere are seven narrow, sligbtly raised and smooth lines, be- 

 sides tbe very strongly raised carina of tbe 8tb interstice ; tbe sutural 

 and 7tb lines are less distinct tban tbe others, and all terminate before 

 the apex ; tbe broad interstices between tbe raised lines arc minutely 

 granulate and opaque, as is also the apical surface, and tbere are 

 traces of two rows of small punctures down each interstice. Tbe bead 

 is of tbe same form as in II. patruelis ; but the mandibles are nearly 

 smooth. Tbe thorax is of a half-moon shape, twice as broad as long, 

 with advanced anterior angles ; but it is not regularly rounded behind, 

 tbe sides being obliquely sinuated, and tending to form a rather dis- 

 tinct basal lobe ; the anterior transverse line unites at tbe apical 

 angles with tbe marginal sulcus.

Angusfior, niger, mimis nitidus ; mandihulis supra mullicarinntis.
