This genus is widely separated from all other genera by its uni(|ue com- 

 bination of distinct characters. It has the rostrum and legs of the geiuis I.achnu*. 

 the wing venation of Chaitophoriis and the body resembles soniewhat that of the 

 genus Aphix. though there .an- no cornicles. In consi<iering the antennn- alone 

 the insect might be placed in the tribe Chailophorini, but a study of the indi- 

 vidual articles excludes it from Antaphh which has the spur of the sixth seg- 

 ment above five times as long .as the segment. In Chaitaphorus the spur of the 

 sixth segment is .about six times as long as the sixth segment and also longer 

 than article III. In Si/mdohiiis the s))ur of the sixth segment is shorter than the 

 segment. In Thomasia the spur of the sixth segment is shorter than the segment. 

 From the description as giv< n .above it seems h.'irdly worth while to make further 

 comparisons with the genera which it most resembles. I-'iilldirni/a has not th<' 

 antenna- scgment.ation. stigm.'i, or stigmal vein of I.acbnus, nor the specific char- 

 actiTs of Aphis. Though .a subterranc-m form it has neither the .antenna- nor the 

 wing vcn.itloii of .iiiy yet described. In consideration of these facts I have not 

 hesit.atdl to e.ill it a new genus. With others this species was sent to \V. M. 

 Davidson of .>s.in .losi- who writes as follows: "No. ','() is certainly a peculiar 

 insect. I am viry glad to h.ive specimens of it. N'ery liki-ly it is a new genus." 

 The genus is n;im<-d in honor of Mr. Fnllaway. who lias worked extensively on tin- 

 .'Xphidida- of H.-iwaii.
