punctuivs. Ejus sniiill and tiat. Thdnt.r ratlici Inoador than lonji, its sides 

 neiivlv straif^ht, only slightly luivcd towards tlu' obtuse anterior ani^lcs, 

 the margins thin there hut somewhat oxplanate behind, posterior angles 

 obtuselv rectangtdar. the base and apex widely incurved ; disc convex, 

 th«> sj)ace near the hind angles flattened but not foveate. with a h'w distinct 

 scattered punctures. Kh/Int of the same width as the thorax, their l)n'adth 

 almost double the length, the shoulders with thickened subdentiform 

 margins, apices very slightly rounded, their surface feebly rugose and with 

 verv few rather indetinitc punctures. Ilnid-bodif elongate, without lateral 

 margins. 5th segment longest ; 6th short, half the width of the preceding 

 one : 7th obconical. its apex medially yet only moderately prominent, 

 but acutely prolonged at the sides ; the few fine yet distinct punctures are 

 almost arranged in 2 transverse series on tlu^ basal 5 segments. Inter- 

 mediate (ihiftc setose externally, the posterior simple. 



The hairless surface, short wing-cases, entire absence of thoracic foveae, 

 the disposition of the punctures on the dorsal segments, and the strongly 

 produced outer angles of the terminal one distinguish this species. Its 

 nearest ally is //. lacvujalu.s.

.'5043. Holotrochus montanus sp. nov. 



Cylindric. nude, shining : black, the palpi, antennae, and legs piceo- 

 rufous. 



Head tinelv punctured, more distantly behind than in front. Et/cs 

 subdepressed but distinct. Thorax quadrate, base and apex subtruncate, 

 its sides tinelv nuirgined and only sliglitly rounded, nearly straight from the 

 middle to the rectangular posterior angles ; the surface iinely and distinctly 

 but not closely punctured, the fovea near each hind angle moderately large 

 and quite definite. Scutellum sparingly punctate. Ebjlrn quadrate, with 

 rectangular shoulders, slightly medially incurved behind ; their surface 

 with distinct l)ut not seriate punctures, the sutural striae not quite straight. 

 fIit)(I-l)o(ltj without lateral margins, equal to the thorax and elytra con- 

 jointlv in length ; rather distantly, moderately finely, and somewhat irregu- 

 larlv punctured, the intervals not quite smooth ; the 5th segment rather 

 longer than any of the others. Front and intermediate tibiae finely spinose 

 externallv ; the posterior more finely, and near the extremity only. 



Antennae with fine pale pubsecence ; 2nd joint more slender, but as 

 long as the exposed portion of the basal one ; 3rd elongate, but not as long 

 as the following 2 taken together ; 6-10 differ but little from each other, 

 rather broader than the preceding ones, and laxly articulated ; the terminal 

 subol)conical. 



The darker colour, less-prominent humeral angles, more definite basal 

 ijupre.ssions on the thorax, and smaller size distinguish this from //. hrouni.
