VI. MORMIDEA Amyot & Serville, 1843, 134. 



Small oval or elongate-oval subconvex species having the 

 head broad, more or less declivent, cheeks slightly concave, 

 usually very coarsely punctate, reaching tip of tylus ; beak 

 reaching hind coxae, its second joint longer than third and 

 fourth united ; eyes globose, prominent ; pronotum with front 

 portion strongly declivent, its side margins unarmed, humeral 

 angles either obtusely rounded or spinose, disk evenly punctate 

 and in our species bearing one or two callosities ; scutellum 

 shorter than corium, its apex narrowly rounded, frena extend- 

 ing beyond its middle ; connexivum narrowly or not at all ex- 

 posed ; membrane with veins simple and parallel ; tibiae not 

 grooved ; osteolar opening with a short auricle, but without a 



-"'This genus is included as its single species, /'. podopioides Uhler (1863, 364), 

 has been taken in Missouri and at Fort Madison, Iowa, on the Mississippi River just 

 across from Illinois. It is 8.5 — 11 mm. in length, brownish-yellow in hue. with the 

 humeral angles emarginate, scutellum with a broad Y-shaped ridge and margins of 

 abdomen strongly serrate. Its general range is western, extending from the Missis- 

 sippi River to the Pacific. The genera I'ddirus and .Klin, extialimital members of this 

 subtribe, have been erroneously recorded as being represented in our territory; the 

 former by Van Duzee (1904, 78) and Hart (1919, 180) as occurring in Florida, but 

 the specimen of P. viduus (Voll.), on which the records were bused, was taken in 

 Arizona, not Florida, as shown by Barber (1910, 35) and Van Duzee (1917, 44). 

 The specimen of 32lia americana Dall. mentioned by Van Duzee (1904, l!M as having 

 been taken by Provancher in Quebec, has since been shown by Van Duzee (1912, 318) 

 to be a dark example of Neottiglossa undata Say.
