TitleA new species of the Rhynchophorous genus Cryptoderma
JournalNotes from the Leyden Museum
AbstractThis new species, of which I have a single male-specimen before me 2), is a somewhat aberrant one as to shape and structural characteristics, the prothorax being considerably narrower than the elytra at the shoulders, the elytra being strongly costate and the apical tubercles of the elytra being strongly developed; moreover the pits by which the upper surface is covered are very large and deep.
Length (from the anterior margin of the prothorax to the apex of the elytra) 12 mm.; greatest width (across the shoulders) 5 mm. — Covered with a brownisch crust, more greyish on the under surface, legs and antennae, and provided above with the following dirty white markings: on the pronotum three longitudinal lines (one along the middle and one on each side entirely visible from above); on the elytra a dorsal cross in the middle, its posterior half less distinct than the anterior half which latter is united with the base of the elytra by a prolongation of the lateral thoracical lines; the declivous portion of the apical tubercles, the humeral region, the lateral margins of the posterior two-thirds of the elytra and the scutellum are likewise dirty white; beneath the indistinct lateral stripe on the prosternum, just above the coxae, and the lateral margins of the meso- and metasternum dirty white.
