DESCRIPTIONS OF THREE NEW SPECIES OF CETONIID^. 225 



Among some specimens from Esher, collected in 1900, in my 

 collection, is a female that, so far as concerns the right fore 

 wing, is typical. On the left fore wing, however, spots 3, 4, 5, 

 are confluent, and there is a red dash from 3 almost effecting a 

 junction with the united basal spots (1, 2). Two other speci- 

 mens (males) from the same locality and taken in the same year 

 may be mentioned as peculiar. Each of these has a small red dot 

 before spot 4, on the left fore wing ; in all other respects these 

 examples are typical.

DESCRIPTIONS OF THREE NEW SPECIES OF 

 CETONIID.E FROM THE INDIAN EMPIRE. 



By Oliver E. Janson, F.E.S. 



Diceros gracilis, n. sp. 



Body elongate and narrowed behind, shining black, sides of the 

 thorax with an ill-defined red marginal band more or less dilated be- 

 hind ; elytra with a large pale yellow central patch, pygidium and apical 

 segment of the abdomen red. Head sparsely punctm-ed at the base, 

 a little impressed and obliquely striated on each side between the 

 eyes ; clypeus slightly dilated in front, rather coarsely punctured, the 

 side margins raised, the apex slightly rounded and with the margin 

 evenly retlexed. Thorax finely and sparsely punctured, a large trans- 

 verse impression on each side at the base with coarse horseshoe 

 form punctures. Scutellum with remote line punctures or almost 

 impunctate. Elytra wdth eight regular rows of horseshoe form 

 punctures which do not extend to the apex, the sutural row strongest 

 and the two outer rows indistinct in some specimens, the apical part 

 strigose. Pygidium strongly transversely strigose. Under side and 

 legs strigose and coarsely punctured ; mesosternal process very long 

 and curved inwardly towards the apex ; abdomen very deeply and 

 broadly impressed in the male, convex and more strongly punctured 

 in the female ; anterior tibiae w'ith a strong subapical marginal tooth 

 in both sexes. Length, 12|-13| mm,

The small narrow form, punctured impressions on the thorax 

 and strongly punctured elytra of this species readily distinguish 

 it from D. ciivera, Newm., to which it is most nearly allied, and 

 its simple unarmed clypeus at once separates it from D. childreni, 

 Westw, The size of the yellow elytral patch varies a little, but 

 is very similar to that in the latter species. 



TcBuiodera idolica, n. sp. 

 Black, above dull with short grey pubescence, under side and legs 

 shiny and with longer and denser pubescence. Above wath ashy- 

 grey markings disposed as follows : on the head two longitudinal
