 about Dunedin in early spring 

 on low vegetation in moist 

 grounds ; hibernates beneath

VI. Atrachelus Amyot & Serville, 1843, 374. 



Small elongate-oblong species, having the front lobe of head 

 shorter than hind one, the latter gradually tapering from the 

 eyes backward ; pronotum short, not greatly narrowed in front, 

 its disk with two obtuse ridges extending back from middle 

 of front lobe nearly to base of hind one and ending in two 

 rather stout suberect spines, the humeral angles each with a 

 similar spine ; scutellum small, with the usual basal V-shaped 

 ridge, its apex obtuse ; elytra reaching tip of abdomen ; con- 

 nexivum narrowly exposed ; legs slender, the front femora un- 

 armed, moderately swollen, a little shorter than hind ones. 

 Genital plate of male oblong-oval, convex, its apex unarmed. 

 Three species are known, one from Argentina, a second from 

 Panama, the third occurring in our territory. Fracker in his 

 key (1913, 224) has erroneously placed this genus under the 

 section having the "pronotum unarmed on the disc."
