HELOTA SEMIPURPUREA. 211 



basal half. The scutellum transverse, glossy and irnpunctate. 



Elytra parallel, flattened along the sides, broadly and 

 conjointly rounded and narrowly dehiscent at the apex, 

 and with a minute sutural tooth ; the apical margin is 

 minutely sinuated ; each elytron with ten regular striae 

 of punctures which become larger towards the sides; the 

 interstices are alternately raised; the 2 nd and 5 th costae 

 only join the apical margin ; an oblique callosity is present 

 on each elytron between the 3 rtl and 6 th striae just before 

 the black apical half; it shows small but distinct punc- 

 tures belonging to the 4 th and 5 th striae. 



Under surface: the triangular middle portion of the 

 head is remotely covered with distinct punctures, the punc- 

 tures on the lateral portions are larger and more closely 

 set; the sides of the sterna and the elytral epipleurae 

 along the inner margin of the basal fourth are sparsely 

 punctured ; the metasternum has, on the middle of the 

 base, an ovate spot of hair-bearing punctures; the ventral 

 segments are finely punctured near the base at the sides 

 and a small group of hair-bearing punctures is present on 

 both sides of the middle ; the basal ventral segment is 

 shallowly impressed along the middle, the impression pro- 

 vided in the middle with a small tuft of fulvous hairs; 

 the apical ventral segment is broadly truncate posteriorly 

 and provided in front of the truncation with a large semi- 

 ovate smooth depression. 



The legs are slender and elongate, apparently impunctate ; 

 the anterior femora are covered along the underside with 

 minute warts or granules, the anterior tibiae are slightly 

 curved, fringed with fulvous hairs along the inner margin 

 of the apical half; the intermediate tibiae with an almost 

 inconspicuous triangular tooth at the end of the underside; 

 the posterior femora slightly curved, flattened beneath, 

 the posterior tibiae with a tuft of long fulvous hairs at 

 the end.
