Hub. Cayambe (15,000 feet); Chimborazo (15,800 feet). 



Elongate, narrower in front than behind, rather convex, piceous, shining, 

 very sparingly covered witli tine yellow iiubescence. Head very broad, 

 obsoletely and latlier closely punctured, the median impression indistinct, the 

 sides slightly swollen near the base ; eyes lateral, not prominent ; rostrum 

 narrower in front than behind, very feebly constricted in the middle, with a 

 strong longitudinal impression on the disc extending from between the eyes 

 to just behind the a2)ex. Antenna' reildish testaceous, tlie club dusky and 

 clothed with short and rather dense grey pubescence. Prothoiax very small, 

 transverse, at the base as broad as the head, rather strongly constricted both 

 in front and behind, finely and rather closely punctured in front, the punc- 

 tui'es gradually disappearing posteriorly and leaving the basal half almost 

 impunctate, the pubescence near the sides rather long and somewhat closer 

 than on the disc ; the lateial margins Ijetween the constrictions strongly 

 arcuate. Scutelluni small, neaily triangular, impunctate. Elytra more than 

 twice as long as the head and prothorax together, ovate, narrower in finnt 

 than behind, feebly striate-punctate, the stripe very obsolete posteriorly, the 

 interstices broad, not raised and smooth ; humeral angles rather prominent ; 

 sides arcnately rounded to the a}>ex. LTnderside rather j)aler in colour than 

 above ; the sternum very finely punctured ; abdominal segments finely 

 aciculate transversely, very spaiingly and obsoletely punctured. Legs pitchy 

 red, the knees and upper sides of the femora near the liase slightly dai'ker. 

 Length, 7^-9 mm.
