SUBFAMILY III. — DUFOURIELLIN^. 639 



with smooth area larger. Clavus coarsely, sparsely and shallowly punc- 

 tate. Length, 1.5 — 1.8 mm. 



Ft. Myers, Moore Haven, R. P. Park, Lakeland and Dunedin, 

 Fla., Nov. 18 — March 29. More common at Dunedin than in- 

 sidiosits, and taken in small numbers at the other stations by 

 sifting weed debris, sweeping flowers, especially those of the 

 hoary lupine (Lupinus diifusus Nutt.), and beating bunches of 

 Spanish moss. A half dozen specimens were taken Feb. 

 20 from beneath boards in a barn-yard near Dunedin. The 

 small size, and wholly pale antennas and legs distinguish it at 

 once from our common form. It agrees in all respects with 

 Champion's description except that his unique type from 

 Guatemala had the "anteocuiar portion of head, rostrum, an- 

 tennae and legs testaceous," whereas in the Florida specimens 

 the first two parts mentioned are darker than the legs and an- 

 tennas. Described from Guatemala and not before recorded 

 from this country. 



Subfamily III. DUFOURIELLIN^E Van Duzee, 1916, 35. 



This subfamily, the Division Xylocoraria of Reuter and Cham- 

 pion, comprises small oblong or oval species which were by 

 Reuter separated from our other Anthocorids only by the ab- 

 sence of a hamus in the cell of the inner wing. As shown in 

 the key to subfamilies there are two more easily recognized 

 characters which can usually be used, viz., the much more 

 deeply emarginate hind margin of pronotum and the trans- 

 versely sulcate scutellum, but these are to some extent variable 

 and the group is in reality a difficult one to define. The antennae 

 vary in structure, in some genera resembling those of the 

 Lyctocorinae, in others of the Anthocorinae. About a dozen 

 genera of the subfamily were recognized by Reuter, six of 

 which are represented in our territory.
