640. — Apellatus Mastersii. n. sp. 



Length 3 1 lines. 

 This species is larger than the last, and of a darker red colour, 

 with the maxillary palpi less elongate, the thorax proportionally 

 less long- and more rounded at the anterior angles, and with the 

 elytra more deeply striato-punctate, and entirely black excepting 

 a testaceous patch at the base. 



641. — Metistete Pascoet. n. sp. 

 Length 6 lines. 

 Black, nitid. Head and thorax finely punctate, the latter 

 small, subquadrate, rounded at the anterior angles, and scarcely 

 broader at the base than at the apex. Elytra much broader than 

 the thorax and broadest near the apex, subacuminate at the apex, 

 three times longer than the width, and sharply striato-punctate. 

 Legs pale red. AntennsB, palpi, and labrum, piceous red. 



642.— Atkactus ruficollis. u. sp. 

 Length 4 lines. 



Red, nitid, and thinly punctate. Thorax longer than the 

 width, a little narrowed in front, truncate at the apex and base, 

 and rather deeply impressed at the base of the median line. 

 Elytra of a brilliant purplish blue, and striato-punctate. Legs and 

 prothorax red. Tarsi brown. Abdomen, meso- and meta-thorax 

 black. Antennge dark brown, joints 4 to 10 broad and subserrate. 



This species and the following ought to constitute a new 

 genus. I place them at present with Atractus, because it is not 

 improbable that the genus Idcymnius of Bates, of which I have 

 never seen the description, may have been made for one of these 

 very species. 



643. — Atractus ctaneus. n. sp. 



Length 3 1 lines. 

 This species only differs from the last in being smaller, in 

 having the head and thorax of a bronzy black, and in having the 

 legs brown and finely pubescent.
