436 Mr. J. S. Baly's descriptions of 



and by the absence of tlie longitudinal sulcation on the 

 dorsal surface of the tibiii? ; from A])]tthonn* it is separated 

 by the iniai'uied apices of the four anterior tibiae. 



Sutrea elcgaiis. 



Flava, nitida, oculis, femomm posticorum apice elytris- 

 que higris, his tcnuissime, confuse punctulatis, ntrisque 

 apice maculisque duabus magnis flavis. 



Foem. — Abdominis segmento ultimo apice obtuse rotun- 

 dato. 



Long. 3^- — 4 lin. 



llah. — New Guinea ; collected by Mr. AVallace. 



Head shining, impunctate, face elevated between the 

 eyes, the elevated portion forming a broad ill-defined carina, 

 the apex of which is angulate ; encarpaj subtrigonate, con- 

 tiguous ; antennas rather more than half the length of the 

 body, slender, filiform, 3rd joint much longer than the 2nd, 

 outer joints stained with fuscous. Thorax more than three 

 times as broad as long; sides rounded, slightly sinuate just 

 behind the anterior angle, the latter very obtusely rounded, 

 hinder ano-les armed with a small lateral tooth : surface 

 smooth, very minutely and subremotely punctured, lateral 

 border reflexed. Scutellum rufo-piceous, semi-rotundate. 

 Elytra very finely pimctured, black or pitchy-black, each 

 with the apical border, together with two large irregular 

 transverse patches, yellow. These patches, which are 

 abbreviated externally at a distance from the lateral 

 border, extend inwardly nearly to the suture ; they are 

 placed one before the middle and the other between the 

 middle and the apex. 



Sutrea hexaspilota. 



Anguste ovata, convexa, piceo-fi.ilvo, nitida, femoribus 

 posticis piceis ; thorace flavo-albo, impunctato ; capita 

 (antennis exceptis) elytrisque nigris, his tenuiter punc- 

 tulatis, ntrisque maculis tribus, duabus subrotundatis vix 

 ante medium transversim positis, unaque transversa, sub- 

 lunata, ante apicem posita, flavo-albis. 



* Dr. Chapuis errs in statirifr that the four anterior tibire in Aphthona 

 are without apical spines ; they arc present in all tlie species that I have 

 examined, but are frequently hidden by stiff hairs, and there£oi-e difficult 

 to discover without a good lens.
