Type material. Lectotype^, without data (" filiformis " Fabricius' handwriting), 

 Zool. Mus. Copenhagen ; syntypes, 1 <$, 1 $, with no data, Zool. Mus. Copenhagen. 



Other material. Mexico : 1 ? ; U.S.A. : 6 cJ, 10 $ ; Cuba : 1 <J ; Colombia : 

 2 g, 1 $ ; British Guiana : 2 <$, 2 $ ; Leeward Islands : 2 S, 2 $ ; Brazil : 

 21 <J, 14 ?• 



The range of this species extends in the east into the Leeward Islands and in the 

 west into Mexico and Gorgona Island, Colombia. It is the commonest Central 

 American species and in the north is found in Texas and Leesburg, Florida. Adults 

 seem to be very common in August. 



This is close to S. (0.) furcifera (Westwood) and can be separated from it by the 

 absence of red median longitudinal line on abdominal venter. 



Four syntypes from Fabricius' collection have been examined ; all except one <$ 

 represent the present concept of S. (0.) filiformis (Fabricius). One £ with Fabricius' 

 own label "filiformis " has been designated lectotype of Stenocoris (Oryzocoris) 

 filiformis (Fabricius) and has been given a lectotype label. The exceptional <$ 

 represents S. (0.) fabricii sp. n.
