Show 264 MR. M. JACOBY ON COLEOPTERA [May 21, material, as descriptions from single specimens (unless particularly distinguished in one way or other) are not desirable, taking into consideration the variability of the Phytophaga. Perhaps it is not out of place here to caution future collectors of these insects against the practice of gumming them on small pieces of cardboard, since it is in most cases necessary to examine the undersides of the specimens. These suffer greatly during relaxation, and are in many instances almost impossible to clean so that the small spines and structures of the legs and antennae shall be made plainly visible. The specimens should in all cases be sent home in sawdust and left to be mounted in one way or other after they have been examined. I add here the localities in which M . Simon obtained the specimens :- La Guaira (level of the sea), October 1887. Caracas (elevation of 922 metres), October till January 1888. Colonia Tovar, Province Guzman Blanco, mountains of 1900 metres at an average. Hacienda de Corosal, near Caracas, February 17th-21st. Puerto Cabello (level of the sea), February 27th-29th and March. San Esteban, hot forest near Puerto Cabello, March 1st-26th. Valencia, March 29th till April 6th. The collection, although not large, contains a good many apparently undescribed species; those which are known are for the most part also found in Colombia and other parts of South America ; very few collections have to m y knowledge been sent from Venezuela, which offers no doubt a rich field to the Entomologist. LEMA PATRUELIS, n. sp. Head, the antennae (the three apical joints excepted), the breast, and the four anterior legs black ; thorax fulvous, impunctate ; elytra flavous, a transverse band at the base and another below the middle black ; posterior femora flavous. Length 3 lines. Head black, impunctate, eyes deeply notched ; antennae extending to half the length of the elytra, black, the apex of the ninth and the two apical joints entirely fulvous ; thorax slightly broader than long, dark fulvous, the sides deeply constricted, the basal sulcation distinct, the surface entirely impunctate ; scutellum black : elytra scarcely perceptibly depressed below the base, the anterior portion distinctly, the posterior one very finely punctured, the interstices flat, the lateral margin raised; the disk flavous, interrupted by a broad bluish-black band at the base, extending to the sides, having its posterior edge sinuate, and by another transverse band placed near the apex, not quite extending to the extreme margin ; this band has its upper margin convex near the sides but narrowed towards the suture, and its lower margin slightly concave : the breast and the four anterior legs (a flavous spot at the underside of the femora excepted) black; abdomen and the posterior femora fulvous, the extreme apex of the latter and the tibiae and tarsi black. |
