dominal sexual characters and in other details. The male of grandis 

 is said to have "the fifth ventral plate widely einarginate with a 

 carina from each side of the excision." No carinae are present in the 

 male of wickhami and, in addition, the form of the body is differ- 

 ent, being not truly parallel; the elytral punctuation is less deep and 

 the series less conspicuously, arranged in pairs. In grandis the legs 

 are fuscous, the tarsi pale, and the disk of prothorax finely, transversely 

 wrinkled. 



Mexico City, Mexico. Received from Prof. Wickham, by whom 

 the type has been retained.

Cymatodera discoidalis Chevrolat. 



Cymatodera discoidalis Chevr., Rev. et Mag. Zool., 1843, p. 10. 



A female specimen from Jalapa, Mexico, given the writer by Prof. 

 Wickham is 13.3 millimeters in length. The form is rather slender 

 and the color markings of elytra are as in the type specimen, except 

 that the ante-median fuscous fascia is narrow, very irregular in out- 

 line and widely interrupted at the suture. The structure of the an- 

 tennae is not given in the original description. The form of the apical 

 abdominal segments and antennal structure are, however, of such 

 value that species known to be distinct could not well be separated by 

 use of other characters. In discoidalis the antennae are slender, longer 

 than head and thorax; the basal joint large and stout; joints two to 

 eleven much more slender, feebly serrate, the second to ninth grad- 

 ually increasing in length ; the tenth slightly shorter but the eleventh 

 slightly longer than the ninth. The abdominal sexual characters of 

 the male are given by Rev. H. S. Gorham (Biol. Centr.-Amer., in, 

 Pt. 2, p. 131). In the female the ventral segments are wider than 

 the corresponding dorsal segments; the fifth ventral very deeply and 

 broadly arcuately emarginate; the sixth ventral shorter than the 

 last dorsal, deeply depressed at the middle, deeply and broadly emar- 

 ginate at apex, the sides arcuately elevated; the last dorsal truncate. 

 In the specimen before the author the first to fourth ventral segments 

 have the sides and posterior margins testaceous, the fifth and sixth 

 are entirely testaceous. (PI. VI, fig. 20.) 



Cymatodera grossa Gorham. 



Cymatodera grossa Gorh.,Biol. Centr.-Amer., in, Pt. 2, 1882, p. 188. 



A specimen of this species from Cuernavaca, Mexico, taken by 

 Prof. Wickham, exceeds in size the type specimens, being 15.3 milli- 

 meters in length (types 10-13 mm.). The antennae extend to base
