Mandersia, n. g. 

 Antenna ad basin rigidee; articulis quatuor ultimis fl-agellum fragil- 

 issimum facientibus. Tibice intermedia et posteriores subtus et intus longius 

 el latins dcpfanatcE. Presternum haud sulcatum. 



Although the number of joints in the antennae is somewhat uncertain, this 

 genus is nevertheless readily distinguished by the structure of these organs, the 

 basal joints forming a closely compacted mass, while the four terminal joints are 

 so loosely connected that the slightest touch disconnects them. These terminal four 

 joints are similar in size one to the other, each almost spherical but the last one 

 with an acuminate tip ; they are setose. Next to these four joints are three others 

 closely connected, and in one aspect looking as though they were only one, the first 

 of these three joints is short, not lunger than broad, while the last of them is longer 

 than broad ; nearer to the base is a very long joint, which perhaps consists of two 

 joints soldered together ; the basal joint is very short and thick, and almost com- 

 pletely concealed by the epistome. Supposing the tlagelhun in my examples to be 

 perfect, and the elongate joint to be really two-jointed, this makes the antenna; to 

 be ten-jointed. They are not drawn into the thorax with the head when this is 

 retracted. The application of the head to the prosternum is very perfect, and the 

 deplanation of the tibiae to permit of perfect adaptation to the femora, when re- 

 tracted, is greater than im any other form. The eyes are laterally placed, and of the 

 peculiar Limnichus form. The other characters that I can see are such as are 

 characteristic of the group. 



I have named this curious genus iu houour of Surgeon-Major 

 .Neville Mauders, who twelve or fifteen years ago discovered it in the 

 Shan States, as well as a number of other interesting insects. 



The genus may at present be placed near Physemus Lee, from 

 which it differs totally in the loosely articulated flagellum of the 

 antenna). 



MaNOKKSIA SOYMNOIOES, il. Sp. 

 Ovalis, nigra, (/riseu-pubesvens, anteuuis pedib usque rufis ; subtiliter, 

 minus dense punctata. Long., 3 mm. 



Thorax strongly transverse ; the anterior angles much depressed, so as to clasp 

 the retracted head ; the anterior margin sinuate on each side so as to allow the 

 antenna} to be directed upwards when the head is retracted; base very closely 

 applied to the elytra, a little lobed in the middle ; finely punctate, pubescent. 

 Eyes concealed when the head is retracted, behind obliquely truncate and straight, 

 in front rounded, not emarginate. Scutellum moderately large, forming an equilateral 

 triangle. Elytra rather finely and sparingly punctate, shining, except that the 

 copious pubescence much conceals the surface ; towards the sides with distant 

 larger punctures serially placed. Under-surface piceous, pubescent, finely punctate. 

 Legs sordid red. 



Hab, : Shan States {Mauders). 



Two specimens only were met with of this interesting little 

 insect.
