RETICULITERMES CLARIPENNIS. new species. 



Winged. — The color of the head and thorax is darker than in 

 R.jlavipes; femora black, rest of legs pale; palpi pale. The head is a 

 trifle broader than in R. flavipes, the lateral and intermediate spots 

 hardly discernible; the fontanelle a trifle farther back than in R. 

 fiampes; ocelli usually fully a diameter (but not more) from the eyes. 

 Pronotum hardly as much narrowed behind as in R. flavipes, slightly 

 emarginate on hind border. In the male the last ventral segment is 

 proportionately longer than in R. flavipes. 



Length to tip of wmgs, 9.5 to 10 mm. 



Soldier. — ^Closely similar to R. flavipes, but the head is more 

 slender, the sides more nearly parallel, and consequently the gula 

 more elongate, the ocellar spot is faint. This had been considered 

 the European i?. lucifugtis; 



but the wings are clearer, [^ / /--/ /. i -v, 



and there is no reason why 

 lucifugus should occur in 

 central parts of the United 

 States. 



Occurs from Manhattan 

 (Kiley County), Kansas, 

 south to Brownsville 

 (Cameron County), Texas , 

 west to Austin (Travis 

 County), New Braunfels 

 (Comal County) and Uval- 

 de (Uvalde County), and 

 Tucson, Arizona, and east to Beaumont (Jefferson County), Texas; 

 also in Monterey, Mexico. (Fig. 32.) 



Type, winged adult.— Cat. No. 21862, U.S.N.M. 



RETICULITERMES TIBIALIS, new species. 



Winged. — ^Almost wholly shining blackish, only the mauthparts, 

 tarsi and tips of tibiae pale, bases of wings blackish; last joint of 

 palpi marked with dark. Head about as long as broad, front margin 

 slightly concave; eyes about their diameter from the lower margin, 

 ocelli a little less than diameter from the eye; lateral spots indistinct 

 or absent; the antennae 16-jointed. Pronotum as wide as space 

 between eyes, slightly concave in front, and plainly indented behind 

 in the middle, hardly as much narrowed behind as in the other spe- 

 cies. Body with hair as in other species. 



Its black color, blackened tibiae, and rather broad head and pro- 

 notum, easily separate it from our eastern species. There are flying 

 records for both spring and fall. 



Length to tip of wings, 9.5 to 10 mm. (Fig. 33.)
