Platysma Sturm. Doj. 



4. F. OBLONOONOTATA. — Dark reddish-ferruginous ; elytra 

 with five or six hirge subsutiiral punctures. 



Inhabits North West TerritDry. 



Body with a hardly perceptible metallic gloss ; head darker ; 

 thorax with the dorsal line very distinct ; lateral basal lines well 

 indented and with obsolete confluent punctures; posterior angles 

 angulated; elytra striated; five or six large indented punctu,*es 

 placed somewhat [426] alternately ou the second and third 

 striae ; marginal ocellate punctures with their regions indented. 



Length nine-twentieths of an inch. 



This is the analogue of the F. uhloiiijopunctata F., correspond- 

 ing in the punctures of the elytra, but differing in color, and 

 having the thorax somewhat more robust. 



5. F. DEl'ARCA. — llcddish-brown ; thorax punctured ou the 

 anterior and posterior margins. 



Inhabits Mexico. 



Body reddish-brown, rather pale ; head much darker, tinged 

 with blackish, impunctured; antennae short, not reaching the 

 base of the thorax ; thorax rather abruptly contracted behind ; 

 anterior and posterior margins deeply punctured, the punctures 

 of the former not extending to the lateral margin ; lateral mar- 

 gin with a puncture furnishing a hair on the middle and another 

 on the posterior angles, which are rectangular ; dorsal line dis- 

 tinct, but not deeply impressed ; basal impressions dilated, and 

 with all the base punctured; elytra with slender striae, not deeply 

 impressed, but with very distinct punctures ; stria obsolete to- 

 wards the tip ; cpipleura and all beneath paler. 



Length nearly half an inch. 



The light color, with tltf punctured anterior and posterior 

 thoracic margins, will distinguish this species. 



It was taken by William Bennett and presented to me by Mr. 

 Maclure. 



Abax Bonelli.

 is the insect that Dejean has recently placed in Ziegler's genus 

 1834.]
