black, conspicuous, exuviae marked by a 

 wbile dot surrounded b_v a \vbiti^li rini;. $ 

 scale extremely inconspicuous. No groups 

 of ventral glands. 2 pairs of lobes. On 

 twigs of'orange seedlings from Japan (Craw). 

 In all its characters this is almost exactly 

 like A. periiicioaitsi^ and would have been 

 assumed to be that hut for the locality and 

 food-plant. It is another *' pln'siological 

 species," like A. coioyains or the West Indian 

 form of A. aitraiiiii. The true ferjiiciostm 

 never attacks orange trees in California, nor 

 is it found on the deciduous tVuit-ttees from 

 Japan which have passed through Mr. Craw's 

 hands, nor in Takahashi's collections. 



Chionaspis difficilis, n. sp. — $ scale about 

 2 mm. long, irregular, from round to suhe- 

 longate, moderately convex, white; exuviae 

 to one side, 2nd skin black or nearly so, 1st 

 skin pale stra\^' yellow. ^ scale white, 

 tricarinale. $ orange-rufous, becoming 



bluish-green when boiled in soda. 



^roup'; 



of ventral glands, caudolaterals 43, cephalo- 

 l.iterals 41-43, median about 37. Median 

 lobes large, diverging; second and tliiid 

 b)bes notched; plates spine-like, large. On 

 Elaeagnus from Japan (Craw). This is a 

 \-ery Diaspis-like Chionaspis. 



C. latus, n. sp. — Allied to C. braziliensis. 

 with a tricarinate white (J scale, and a broad 

 liyriform red-brown 9 scale. The broad 

 llat scale readily distinguishes it. On leaves 

 of orange, Tokio, Japan (Takahashi). 



C. bambusae, n. sp. — J scale white, 

 elongate-p\'riform, exuviae pale straw yellow, 

 second skin with an orange spot at the tip. 

 In size, shape and color it is like C. vaccinii, 

 but it differs in the number of glands in the 

 ventral groups, etc. On leaves of bamboo, 

 Tokio, Japan (Takahashi). 



Mytilaspis carinatus, n. sp. — J scales 



something like M. citricnla, but narrower 

 and with a pronounced median longitudinal 

 keel. 4 groups of ventral glands, of about 4 

 orifices each. Lobes small. Some large 

 spine-like plates. Saccular glands along the 

 pygidial margin. Rows of elongate pores 

 marking the obsolete segments. On a plant 

 like Anthiirium from Central America 

 (Craw). 



M. crawii, n. sp. — $ scale narrow, .about 

 2^ mm. longand A mm. wide, slightly curved, 

 pale orange yellow, exuviae concolorous. 

 Four groups of \'entral glands, caudolaterals 

 of 3. cepbalolaterals of 4. Median lobes 

 very large, rounded at ends, their edges 

 finely serrate. Beneath the epidermis of 

 leaves of Elaeagnus from Japan (Craw). 



Parlatoria theae, n. sp. — $ scales on bark, 

 very inconspicuous, about l| mm. long, oval 

 in outline, slightly convex, pale ochreous. 

 with the 2nd skin black or nearly so. Re- 

 moved from the twig they leave a white mark. 

 9 (after boiling) colorless, lobes pale ochre- 

 ous. Median lobes trilobed. 4 groups ol 

 ventral glands, with a single median one. 

 Caudolaterals 8, cepbalolaterals 20. On 

 tea-plant. Japan (Takahashi). 



P. theae var. viridis v. nov. vel n. sp. — 5 

 scale about i4 miri. long, nearly circular, but 

 the exuviae projecting at one side. Scale 

 white with a more or less pronounced grayish 

 vellow tinge, exuviae dark greenish to black. 

 5 (in soda) bluish-green with the pygidial 

 area pale orange and the region about the 

 mouth sufl^used with brown. Five groups of 

 ventral glands, caudolaterals 16 to 17, cepba- 

 lolaterals 9 to 16, median i to 4. On bark 

 of twigs of an ornamental plant froin Japan 

 (Craw). The tips of the median lobes aie 

 more produced than in theae.
