Habitat : On Achrosiichum caudatum (959), IVedelia paludosa 

 (966), Hibiscus tiliacens (961), Adiantum intefmedum (962), 

 Irichomanes pricrii (955), Conostegia lasiopoda (963), Polypodimn 

 phyllitidus (965), Nephrolepis aciila (53), and A Isophila armata 

 (964), Cocos Island. On I^sychofria 7-ufipes (817), Abingdon 

 Island. On Fsyc/iotria nifipes (865), 1,000 ft., Iguana Cove, Abing- 

 don Island, and on Gossypimn barbadcnse (599), Seymour Island. 



" This is a Calynuiatiis, very similar to C. hesperidi/m, but smaller 

 than this species ordinarily is. The antennas agree with hesperidum, 

 as also do the legs. The insect is evidently ovoviviparous. The slight 

 fimbriation of the tips of the spines is peculiar. C. ttamis (Ckll.)from 

 Trinidad, W. 1., also has the spines occasionally slightly fimbriate, 

 but it is a smaller species (length 1.5 mm.), and the fourth antennal 

 joint is much shorter. I am by no means sure that the Galapagos 

 insect is not a form of C. hcsperiduni, perhaps produced by climatic 

 conditions" (Cockerell, MS.). 



Aspidiotus(Hemibalesia)latani£e.S>X/w;r/. ( Plate V, Figs. 23, 24.) 



Srale of adult ffiitaU. — The scale of the female is circular with the exuvire laterad 

 of the center ; the position of the first is indicated by a ripple like prominence, slightly 

 covered with white cottony wax ; the second skin is slightly reddish brown, with re- 

 mainder of the scale slightly darker ; the ventral scale is delicate, white, and adheres 

 to the bark leaving a white spot when the scale is removed ; diameter 1.7 mm. 



Mature female. — The body of the female is ovate ; pale in color, with the last ab- 

 dominal segment lemon yellow, and presenting the following characters : there are 

 four groups of spinnerets, the anterior laterals vary from five to seven, while the pos- 

 terior laterals contain six ; there is only one pair- of lobes, they are very prominent, 

 about as wide as long, notched on each side, and more or less rounded ; there are two 

 incisions in the thickening of the body wall laterad of the lobes ; plates distinct, forked, 

 about as long as the lobes ; two laterad of the lobes, between the first and second 

 spines, and three more between second and third sj.ines ; the spines distinct, first pair 

 on the lateral margin of the base of the lobes, the second pair midway between the two 

 incisions, and the third pair just laterad of the last incision. 



Scale of 7)1 ale. — The scale of the male is oval in form, very much smaller than the 

 female, but the same in texture ; the exuvije is near the center ; length, about .8 mm. 



Habitat : On Sca/esia hopkinsii {S^i), 1,700 ft., Abingdon Island.
