Occurs only in Arizona, from Nogales, on the Mexican border, and 

 Palmerlee (Huachuca Mountains) ; north of the Santa Rita Moun- 

 tains; Tucson, Catalina Springs, and the Santa CataUna Mountains 

 (Sabino Canyon), in Pima Countj^; Oracle (Pinal County), in the 

 Pinaleno Mountains (Grant Canyon and Post Canyon), at an eleva- 

 tion as high as 8,000 feet, in Graham County; and as far north as 

 Flagstaff and Williams, in Coconino County. (Fig. 39.) 

 Type, soldier.— Csit. No. 21865, U.S.N.M.' 



RETICULITERM ES HUMILIS Banks, var. HOFERI, new variety. 



Soldier. — Differs from Immilis in rather smaller head, in liaving 

 the gula as wdde or a little wider than tvpical form, but noticeabty in 



the much longer, more slender man- 

 dibles; these are plainly longer 

 than the width of the head. 



Soldiers only known from Nogales, 

 (T. E. Snyder, Coll.), and Sabino 

 Canyon, Santa Catalina Mount- 

 ains, Arizona (Geo. Hofer, Coll.) . 



Type, soUier.—Csit. No. 21866, 

 U.S.N.M. 



RETICULITERMES TUMICEPS, new species. 



Soldier.— ^imilsiT to R. tibialis, 

 rather larger, the gula usually a 

 little more slender, but still broader 

 than in many species; head about 

 one and a half times as long as 

 broad in front, but plainly broader 

 behind than in front, especially 

 noticeable when seen from beneath ; 

 mandibles about as broad as head 

 in front; hairs fairly numerous; 

 labrum about as in R. • tibialis. 

 Pronotum considerably narrowed behind, but little indented in front ; 

 the femora are rather more swollen than in R. tibialis. (Fig. 38, 2.) 



Although I can not associate a winged form with these soldiers, 

 the shape of head induces me to think that they represent a new 

 species. 



Stratton, Santa CataMna Mountains, Arizona, 6,000 to 7,000 feet, 

 27 July, 1917 (W. M. Wheeler). 



Type, soldier.— Csit. No. 10543, M.C.Z. 



RETICULITERMES LUCIFUGUS Rossi. 



Colonies of this European species have recently been found at Stony 

 Brook and other localities near Forest HiUs, Massachusetts, by Mr. 

 R. J. Dobson. It is closely similar to the R. hesperus of California in
