398 Mr. G. K. Gude on new Species of 



spines, smaller hairs, and small triangular and larger round 

 glands. The surfaces of the body bear hairs and scattered 

 spines and numerous small and large glands. 



Adult male light yellow ; eyes black. Length, including 

 style, "85 millim., extent of wings 225 millim. Antennae 

 10-jointed ; joint 10 the longest ; joints 3-9 subequal. 



Halteres short, expanded in the middle, bristle fine, with 

 a large hook at the end. Legs long, slender, with numerous 

 hairs. Tibia twice the length of tarsus. Claw very long 

 and slender, one third length of tarsus. Digitules hair-like, 

 short. Style very short, acuminate. The last segment of 

 the body bears on each side of the style one long hair and 

 several shorter ones. The other abdominal segments also 

 bear several short hairs on the lateral margins. 



Hab. Ypirauga. In galls on leaves of a plant of the 

 family Solenacese. 



But few of the galls contain insects, and it is probable that 

 they are made by other insects and appropriated by this 

 Dactylopius. This species is accompanied by an ant 

 ( Cremastogaster ?) .

LI. — Descriptions of new Species of Japanese Land- 

 Shells. By G. K. Gude, F.ZS. 



Among a number of Helicoid land-shells received from 

 Mr. Hirase the following appear to be undescribed : — 



Arnouldia ceratodes, sp. n. 



Shell imperforate, trochoid, smooth, shining, dark corneous; 

 spire depressed, apex obtuse, suture impressed. Whorls 5^, 

 increasing slowly, the last not descending in front, at first 

 keeled at the periphery, becoming rounded towards the 

 mouth. Aperture oblique, lunate; peristome thin, straight, 

 acute; margins distant, upper descending slightly, colu- 

 mellar margin slightly expanded above, the umbilical region 

 sunk. 



Diam. maj. 5'5, minor 4*75; alt. 4 millim. 



Bab. Kashima, prov. Harima. Type in my collection. 



The new species is allied to A. stenogyra, A. Ad., but it is 

 darker and considerably larger and more deeply sunk around 

 the umbilical region. Six specimens were received.
