SOME INJURIOUS NEOTROPICAL WEEVILS. 63 row of round flattened shiny granules, the spaces between the granules dull and thinly clothed with minute hair-like scales ; the posterior margin not denticulate. Legs with numerous short recumbent pale setae ; the femora all with a sharp tooth in both sexes and closely set with flattened, transversely confluent shiny granules ; the tibiae with shallow, longitudinally confluent punctures, all uncinate and mucronate at the apex in both sexes, and with a sharp median tooth on the inner edge of the front pair in the <$ only. Sternum set with flattened granules ; the intercoxal process of the mesosternum not tuberculate and twice as broad as that of the prosternum. Length, 16-5-20-5 mm. ; breadth, 8-10-5 mm. Lesser Antilles : Grenada (H. A. Ballou). Described from 21 specimens. The nearest allies of this insect are the Brazilian species, C. undulatns, Gyl., and C. parens, Fhs., especially the latter, which is very similar in its general form and sculpturing ; but it lacks the thoracic markings and the transverse bands on the elytra, when present, are very indefinite and irregular, the basal one lying actually on the basal margin. But both these species differ, inter alia, in the following structural characters : the prosternum is not tuberculate between the coxae ; the front femora bear no tooth in either sex ;• the front tibiae in the c? have no median internal tooth ; and the front coxae in the same sex each bear a stout spur. The species is dedicated to Sir Francis Watts, , Commissioner of the Imperial Department of Agriculture for the West Indies, who forwarded specimens with the information that the insect was doing appreciable damage to pineapples in Grenada. I am indebted to Mr. H. A. Ballou, Entomologist to the Department, for examples of the larvae (fig. 2) and for the following interesting notes on the Fig. 2. Larva of Cholus wattsi, sp. n. ; a, pos
