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 antennse shall be made 

 plainly \isible. 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 speci- 

 mens : — 



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 lst-26th. 



Valencia, March 29th till April Gth. 



The collection, although not large, contains a good many appa- 

 rently 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 my knowledge been sent from Vene- 

 zuela, which offers no doubt a rich field to the Entomologist. 



Lema patruelis, n. sp. 



Head, the antennse (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 ; antennse 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 ; scutelium black : elytra 

 scarcely perceptibly depressed below the base, the anterior portion 

 distinctly, the posterior one very finely punctured, the interstices fiat, 

 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.
