long slender setae and between these a conical invaginated tube show- 

 ing at the inner end a hairless anal ring; derm dorsally and along 

 the margin with large and prominent 8-shaped pores, each set at 

 the bottom of a short tube, and present in two different sorts of 

 arrangement, as shown in figure; no further evidence available to 

 indicate whether such difference is connected with different sexes or 

 what is responsible for it; spiracles small, each accompanied by a 

 single multilocular disk gland pore. 



One other species, F. semiocculta Maskell, has been placed in this 

 genus. The mounts of this species in the Maskell collection are in 

 such condition that it is not possible to be certain regarding the 

 correctness of this placing. It appears to have been properly as- 

 signed to Frenchia.1 however, and may readily be separated from the 

 type species by the fact that the " tail " is much shorter, stouter, and 

 semicircularly rounded at apex. 



The following generic diagnosis is based principally on the type 

 species, with such modifications as would seem to include the other 

 described species. 



GENERIC DIAGNOSIS OF FRENCHIA. 



Asterolecanine coccids producing peculiar woody galls on or in the 

 host, the adult female disk-shaped, with a long tail-like prolongation 

 of the apex of the abdomen, chitinized at tip ; antennae very much 

 reduced; legs wanting; mentum 1-segmented; anal ring developed 

 into a short tube and without setae ; derm with circular multilocular 

 disk pores, long tubular ducts, and minute 8-shaped pores; derm 

 setae few, small and scattered, larger and more numerous on the 

 abdomen ; no traces of spiracular spines or thickenings around anal 

 ring; intermediate stage female flattened turbinate; antennae very 

 much reduced; legs wanting; only multilocular disk pores and 

 minute 8-shaped gland pores present; otherwise much as in adult; 

 larva elongate oval; antennae apparently 6-segmented; legs slender, 

 digitules all normal, slender, knobbed, claw without deniicle; body 

 with two long apical setae ; anal ring minute, without setae, placed at 

 bottom of invaginated tube ; dorsum and sides of body with rows of 

 large 8-shaped pores. 



As indicated in the generic description, this genus is placed with- 

 out question in that group of genera containing Asterolecaniu'tn and 

 others, a position which has already been suggested by Mr. E. E. 

 Green.^ The gall-making habit and the development of the long 

 " tail " are the only characters showing any connection with the so- 

 called Brachyscelini while all of the morphological characters avail- 

 able for study indicate a definite relationship with the Asterole- 

 caninae.
