LANGURIIDAE FROM BURMA 275 



from tlie latter the pure red underside, much less coarse punc- 

 turing , and longer abdominal lines at once separate it. If the 

 generic characters are studied I do not think tliere will be any 

 difficulty in recognising it. Very rarely examples occur in which 

 the scutellum is black, and similarly the base of the antennae 

 is black, at least above in some. 



23. Anadastus nigriventris, n. sp. 



Sanguineo-rufus, antennis basi excepta^ pedibiis^ metasterno abdo- 

 mineque nigris, capite prothoraceque crebre fortiter punctalis, hoc 

 magis oblongo obsolete sulcata^ elylris caerideis. Long. 6.5-8 mUlim. 



Femina? prothorace subquadrato, hand sulcato; antennis articulis 

 sex basalibus, femoribus tibiisque anticis rufìs.

A species very closely allied to A. gratus, but with the l^reast 

 and abdomen black beneath ; at the same time the thorax ap- 

 pears rather more elongate, and is evidently sulcate for nearly 

 its whole length, though in a very obsolete manner. One spe- 

 cimen which agrees with these in most of their ditterences from 

 -4. gratus has the thorax shorter, and may possiljly be the fe- 

 male sex. Considering that all these examples are from the 

 higher altitudes of Asciuii Ghecù I feel obliged to treat them 

 at present as a distinct species. The difference of colour in the 

 body, has hitherto always proved to be a specific difference. 

 There are however certain specimens from Garin Asciuii Ghecù 

 which while having the body red, have a more or less sulcate 

 thorax, and this renders this conclusion somewhat doubtful. 



24. Anadastus lugens, n. sp. 



Niger, capite prothoraceque interdum picescentibus, creberrime 

 minute distincte punctatis, hoc oblongo-quadrato, lateribus sinuatis 

 postice parum angustatis, elytris nigro-viridibus lateribus subparal- 

 lelis, apice truncate; subtus parce punctatus, medio fere laevi. Loiig. 

 6.5-9 millim. 



Hab. Burma, Garin Gheba. 



This insect from its dark colour, and from the size, at first 

 rather closely resembles Stenodastus lugubris , Ijut is readily
