scutellum^ being of a ruddier ochreous tinge. Body beneath 

 and legs of a tawny colour ; tliighs moderately clavate. 

 Para and the banks of the Tapajos. 



11. Anisopodus humeralis, n. sp. 



A. oblongo-ovatus, niger : thoracis lateribus humerisque fulvescen- 

 tibus ; spinis lateralibus magnis, acutis, obliquis. Long. 3 lin. 



Head dusky, with the sides bright tawny. Antennse pitchy 

 red, tips of joints dusky. Thorax with the sides shining tawny, 

 the middle portion dusky, with two more distinct black dorsal 

 stripes ; the spines as in ^. lignicola — namely, large, acute, 

 obliquely directed rearwards, and followed by a narrowing of the 

 thorax to the base. Elytra oval, narrowed to the tips, which 

 are obliquely sinuate-truncate, the inner angles pointed, and the 

 outer spiniform ; the lateral keels are indistinct ; the surface is 

 closely punctured, the colour sooty black, varied with a few 

 ashy marks, the shoulders having each a triangular tawny spot, 

 which does not cover the scutellum. Body beneath and legs 

 dusky ; hind femora (in the ? ) but slightly clavate. 



One example, S. Paulo, Upper Amazons. It is possible, not- 

 withstanding the great difference in colour, that it may be but 

 a local variety of A. lignicola. 



Two other species of Anisopodus, in addition to the eleven 

 here enumerated, have been described, namely, A. curvilineatus 

 (White, Brit. Mus. Cat. ii. p. 350, pi. 9. f. 1) of South Brazil, and 

 L. j)rolixus (Erichson, Consp. Ins. Peruana, p. 145) of Eastern 

 Peru. The latter is the largest species at present known, and 

 seems to be closely allied to A. arachnoides. I add a description, 

 at the foot, of a fourteenth species*. 



XXVIII. — On the Raphides of Onagracea. 

 By George Gulliver, F.R.S. 



We have already seen ('Annals' for April and July 1863) how 

 well this order is characterized by raphides, so that not only can 

 a plant belonging to it be henceforth truly distinguished from 

 others of nearly allied orders by these acicular crystals alone, 

 but a minute fragment of the leaf or its modifications may be 



* A. canus. — Oblongus, planus, tomento denso canescente vestitus. An- 

 tennae rufescentes, articulis apice nigris. Thorax punctatus, antice 

 nigro bivittatus, spinis lateralibus tenuibus porrectis. Elytra lateribus 

 parallelis, prope apicem subito attenuata, dorso inajqualia, medio for- 

 titer depressa, cai-inis lateralibus acutissimis, apicibus longe niucro- 

 natis ; eanescentia, maculis minutis nigris sparsa, quarum duabus di- 

 stinctioribus prope apicem. Pedes nigricantes, femoribus tibiisque 

 dimidiis basalibus rnfis. Femora postica (maris?) elongata, subito 

 clavata. Long. 21 lin. Hab. Brasilia meridionalis. Coll. Bakewell.
