By Thomas G. Sloane. 



(Continued from Vol.xxxii., p.381, 1907.) 



Subfamily CARABINE. 



Tribe Migadopini. 



Stichonotus, n.g. 



Head short, convex, wide at base and deeply set into prothorax, 

 strongly bordei'ed on each side above base of antennae; one supra- 

 orbital setigerous puncture near eye on each side; eyes not pro- 

 minf-nt. Lahrnm emarginate-truncate, 6-setose, outer seta near 

 anterior angle stronger than others, rising from a large con- 

 spicuous puncture; anterior angles a little advanced, rounded. 

 Clypeus short, emarginate; a setigerous puncture on each side. 

 Menhim short, broad, with a median tooth. Mandibles stout, 

 short, without a seta in outer scrobe. Maxillary palpi with 

 apical joint stout, elongate-oval, obtuse at apex. Labial palpi 

 with penultimate joint bisetose in front; apical joint stout, oval, 

 obtuse at apex. Antennoi slender, reaching behind base of pro- 

 thorax; four basal joints glabrous, first stout, bearing a seta, 

 fourth shortest, third longer than second, about as long as fifth. 

 Prothorax closely applied to elytra, wide at base, strongly 

 narrowed to apex ; anterior and posterior angles triangular, 

 pointed; lateral margins without setae. Elytra shortly truncate- 

 oval, bordered at base, striate; second* and third striae uniting 



* The second stria (counting at the base) is evidently a false stria repre- 

 senting the short stride so often found at the base of the first 

 interstice in the Carahidce. In Stichonotus leal it is unusually prolonged, 

 and reaches to the apical third of the elytra. A similar conformation of 

 the elytral strise may be found in Amarotypus edivardsi Bates, a New Zea- 

 land representative of the tribe Migadopini.
