NOTE ON THE SUBGENUS PSEUD0PA8ILIA G ANGLE. 

 BY MALCOLM CAMERON^, M.B., R.N., F.E.S. 



In ' Die Kafer von Mitteleuropa,' ii, p. 145 (1895), Ganglbauer 

 formed a subgenus, which he placed in the Atheta-groui:), for the insect 

 known to British Coleo^iterists as Sipalla testacea Bris. (see Fowler, Col. 

 Brit. Isls. ii, p. 166). Having recently had occasion to examine the 

 structure of this insect, it a2)pears to me that the tarsal formula is 

 4, 4, 5, so that the species cannot be retained in the ' Myrmedoniini,' 

 and its position near the genus Leptusa is the correct one. 



I give a short account of the mouth-parts and tarsi. 



Labrum transverse, angles rounded ; mandibles curved for apical half, the 

 right one furnished with a distinct tooth at the middle of the inner border. 

 Inner lobe of the maxilla pectinate internally for the anterior half, posteriorly 

 ciliate; outer lobe ciliate at apex. Maxillary palpi 4-jointed, the first joint 

 small, the second elongate, lightly curved, the third as long as the second, the 

 t'oLi) th subulate. JNTentum transverse, quadrilateral, anterior margin narrower 

 than posterior. Labium narrower than the mentum. Tongue narrow, elon- 

 gate, simple. Labial palpi apnroximate at their base, 3-joiuted, lirst and 

 second joints of equal length, the third a little shorter. Paraglossae feeble, 

 ciliate, nort extending much beyond the base of the first joint of the labial 

 palpi. Tibiae ciliate. Anterior tarsi with first three joints short, subequal, 

 the fourth longer than the first three together. Middle tarsi with first joint 

 slightly longer than the second, second and third joints short, subequal, the 

 fourth longer than the first three together. Posterior tarsi with first joint a 

 little longer than the second, second, third and fourth short, subequal, the 

 fifth a little longer than the third and fourth together. All the claws simple.

ON THE OCCURRENCE OF TROGOPHLOEUS SCHNEIDERI GANGLB. 



IN BRITAIN. 



BY MALCOLM CAMERON, M.B., R.N., F.E.S. 



A short time ago Mr. Newbery sent me for examination a small 

 Trogophloeus, captured at Hunstanton, Norfolk, by Mr. Bedwell, which 

 agreed in all respects with T. schneideri Glanglb., originally taken at 

 Boi'kum, and of which there are specimens in my own collection. More 

 recently I have examined examples of the species taken by Mr. Day in 

 the estuary of the River Wampool, in Cumberland, and described as 

 T. hemerimts by Mr. Joy (Ent. Mo. Mag. 1913, p. 155). These also are 

 T. schneideri of Ganglbauer (' Kafer von Mitteleuropa,' ii, p. 659). The 

 insect belongs to the subgenus Troginus, which consists at present of
