226 REVISION OF THE AMYCTKRIDES, ill., 



depressed, siiblateral sulci narrow, deep, obli(|uely set, somewhat 

 riirvedjiiotquite meeting at base, Head and rostrum set with sborl, 

 scattered, decumbent setie. Eyes ratlier large, set high in head. 

 Prothorax('2 x 3 mm.) transverse, apex with a feeble, postocular 

 sinuation, with a marked, transverse, postapieal impression, median 

 and sublateral lines free from tubercdes, but hardly impressed; set 

 with small, rather prominent, subconical tubercdes, more rounded 

 on the sides. Elytra (7*5 x 5 mm.) rather strongly widened to 

 beyond middle, thence narrowed to apex, wdiich is ratlier strongly 

 produced and mucronate; base gently arcuate, humeral angles with 

 an out-turned tubercle, disc with rows of shallow, open, punctiform 

 depressions, interstices Avith small but distinct tubercles, these not 

 present on the declivity; sutural interstice with obscure granules 

 only; second with tubercles, rounded at base, becoming subconical 

 towards declivity; third with a prominent row of rather larger, 

 acutely conical tubercles, becoming larger more posteriori}^; fourth 

 with two or three isolated ones; tiftli with a row of outwardly pro- 

 jecting, acutely conical tubercles, extending from base to edge of 

 declivity; sixth situated on the side, with much smaller ganules;

The above description was drawn up from a cotype of T. spino- 

 sas, received many years ago from Mr. G. Masters. It is probably 

 a female, as the basal, ventral segments are feebly convex ; the last 

 segment lias a shallow, oval, transverse impression at extreme apex. 

 There are seven specimens before me, but I cannot distinguish any 

 difference in sex. The size is very variable, one specimen in my 

 collection measuring 8x5 mm It was on a similar specimen tluit 

 T. I en ui pes Pasc, was founded. This specimen was compared with 

 the type of T. fenuipes by Mr. K. G. Blair, and it agreed well both 

 in size and also in its lack of clothing, thougli this is probably due 

 to abrasion. The species agrees in all details with the description 

 of Amycterus hi/stricosus^ and I have no doul)t that it is correctly 

 identified, though, as mentioned before, I dou})t the correctness of 

 its assignment to Notonophes.
