260 THE KNTOMOLOGTST's RECORD. 



insect is common on the higher skrees. Erchia tiinjalf. — Two very 

 fresh examples only were captured. These were dark, with well- 

 defined fulvous transverse spotted band on the upper side of the 

 fore-wings, and no trace of white transverse markings on the underside 

 of the hind-wings. This is of the same form as was obtained between St. 

 Michel-de-Maurienne and Valloire. The adi/te of Hiibner is given by 

 Staudinger as a var. of li(/i'a from " ? Lapland." I have examined 

 Hiibner's figures {7~)d and 760) carefully, and find them to represent the 

 Lautavet form of eiiri/alc, in which the underside of the hind-wings is 

 without any trace of the white transverse markings of the underside 

 of the hind-wings. The insect is probably rare here, unless it was 

 not yet fully out. The height (above 7,000ft.) would suggest that 

 it was near the limit of its range (altitude). 



A new British Coccid (with plate).

RhhococeKs (?) dcvoniensis, sp. nov. — Sac of adult ? creamy white ; 

 closely felted and firm, but with short erect fibres on the surface ; 

 broadly oval ; convex. Size very variable ; length from 1'75 mm. to 

 2*50 mm. ; breadth from 1*50 mm. to 1-75 mm. ; depth from 1 to 

 1-25 mm. 



Sac of ^ small; white; linear. Length 1'50 mm.; breadth 

 0-50 mm. 



Adult ? reddish-purple ; oval, rounded in front, narrowest and 

 tapering posteriorly ; the extremity with a pair of prominent anal 

 tubercles. Dorsal area (fig. 1) rather convex, and studded with 

 numerous short conical tiibular spines, some of which are rather 

 sharply pointed, while others have the apices slightly truncate. The 

 spines are snbequal in size, and evenly distributed over the surface 

 without any definite marginal series. Ventral surface (fig. 2) without 

 spines, except towards the lateral margins ; their place being taken by 

 a few fine hairs or bristles. There are some small circular pores 

 (ceriferous glands) scattered over the surface of the body. Antenna 

 (fig. H) of seven joints, of which the 8rd and 4th are usually subequal 

 and longest, though sometimes the 8rd and sometimes the 4th is 

 the longer 'I'lie 5th and 6th joints are subequal, and shortest. The 

 terminal joint bears from 10 to 12 stout hairs ; the 3rd joint is hairless ; 

 each of the other joints have two or three placed near the distal 

 extremity. The legs (fig. 4) are rather stout ; the tarsus a little longer 

 than the tibia ; the tibia and tarsus together slightly longer than the com- 

 bined femur and trochanter. The extremity of the tibia is considerably 

 broader than the base of the tarsus ; both joints have some stout 

 spines on the inner margin. Claw stout, and curved at the tip. Tarsal 

 and ungual digitules, both in the form of long knobbed hairs, the 

 tarsals being the longer. Rostrum situate between the coxje of the 

 anterior pair of legs ; the conical mentum doubtfully trimerous, three 

 darker chitinous bands crossing it. Spiracles large and conspicuous, 

 situate posterio-lateradof the first and second pairs of legs respectively. 

 The anal tubercles each bear a longish stout seta at the extremity, 

 and a smaller one on the inner side, besides several conical spines. 

 Anal ring with six stout hairs. Lengtli (of prepared and compressed 

 examples) from 1-50 to 2-50 mm. Breadth 1 to 1-50 mm. 



Adult S not observed.
