a stran^-e gall-making Coccid, OUiffiella cristicola Ckll., and 

 takes the opportunity to publish an illustration which was 

 made several years before Cockerell described the insect from 

 material received from Fort Grant, Arizona. It belongs to the 

 Dactylopiinae just before Eriococcus. A group of sixteen spe- 

 cies of gall-coccids is mentioned and all confined to Australia 

 except one to Hawaii and one to Japan. I have not found any 

 record of the Hawaiian species, and imagine that the record is 

 from specimens in the collection of the Bureau. I have searched 

 over all the literature at hand and have compared specimens as 

 far as possible with every genus, and I have failed to find any 

 genus into which to place it. The nearest being Cissococcus, 

 CklL, into which I shall temporarily- place it adding a few fea- 

 tures of the insect which do not correspond with the genus. 

 Coccids living in coneshaped galls on leaves, body elongate oval, 

 tapering caudad ending in a funnel shaped segment, in the 

 center of which is the anal ring. Legs and antennae present 

 and well formed. Antennae of seven joints. Caudal tubercles 

 well developed forming- part of the funnel shaped segment, sim- 

 ulating those of Lecaniinae. Larva Dactylopine with caudal 

 tubercles well developed. Male winged with caudal tubercles 

 bearing two long stout bristles and a stout spine, 



Cissococcus? oahuensis n. sp. 



Galls in clusters scattered on both sides of leaf, but usually upper 

 surface preferred. Gall cone shaped, somewhat curved and con- 

 stricted near leaf and varying more or less in shape. At times two 

 or three will coalesce. Length about 3 mm and about 1 mm at widest 

 point. 



Female elongate oval tapering gradually caudad, about IVo mm long 

 by about 1 mm at caphalic end. Body of a dirty lemon color, covered 

 slightly with white secretion. After boiling in caustic potash, derm 

 becomes colorless, except the last abdominal segment and appen- 

 dages, which remain light brown. Antennae 7 jointed, segmentation 

 very distinct. Joint 7 longest, joints 1 and 2 subequal. Formula 7 (1.2) 

 4. 6. 3. 5. 



Legs short and stout, with a few scattered hairs. Femur about 

 % as broad as long, tarsus half as long as tibia, claw stout and 

 sharply curved, digitules slender knobbed hairs. Last abdominal seg- 

 ment formed into a funnel, with the anal ring situated about the 

 center. Anal tubercles resembling somewhat the anal plates of Le- 

 canium, form part of the funnel and the derm of all is strongly
