TitleTwo new Asiatic species of the Celeopterous genus Helota
JournalNotes from the Leyden Museum
AbstractStrongly resembling Helota Lesnei Rits. from Kouy- Tcheou (China), of which the type-specimen (♂) is in the Natural History Museum at Paris 1). The new species differs however from it by the sculpture of the elytra (the rows of raised warts or tubercles are less numerous in the new species: 5 in stead of 9), by the testaceous colour of the anterior angles of the prothorax and of the sterna, and in the male sex: by the larger pubescent spots on the middle of the metasternum, by the want of the acute tubercle on the middle of the hindborder of the punctured spot on the middle of the basal-ventral segment, by the otherwise shaped anterior- and posterior tibiae, etc.
Length of the ♂ 8 mm., that of the ♀ 9 mm. — Above very dark bronze with slight coppery tinges, the mandibles green, the anterior angles of the pronotum pale testaceous; opaque in consequence of a very dense punctuation, provided with numerous warts or tubercles of different size and shape, which partly are surrounded with blackish thus forming along the middle of each elytron an ill-defined, rather indistinct blackish vitta; the scape and the club of the antennae pale testaceous, the remaining joints pitchy brown; each elytron with two small round convex yellow spots, the anterior one slightly larger than the posterior. — The under surface of the head (with the exception of the throat), the lateral portions of the prosternum (with the exception of the anterior angles), and the elytral epipleurae metallic green; the throat, the sterna and the abdomen pale testaceous; the coxae are metallic green, the trochanters pitchy brown, the femora pale testaceous with the apical portion dark pitchy with a bright greenish bronze hue on the knees, the tibiae pale testaceous with the base and an incomplete ring just behind the middle dark pitchy or pitchy brown; the tarsi pitchy brown with the base of the clawjoint and that of claws pale testaceous.
