LAMPROSPHERUS.—NODA. - 193 
slightly thickened; thorax at least three times as broad as long, nearly equal in width, the sides very 
moderately rounded and but slightly narrowed in front, the surface very minutely punctured, the punctures 
more distinct at the middle than at the sides, the interspaces very finely granulate, opaque; elytra more 
shining, dark blue, closely and strongly punctate-striate ; legs fulvous. 
Hab. Mexico, Acapulco in Guerrero (ége). 
A single specimen. The opaque and minutely punctured thorax and the fulvous 
antenne and legs characterize this species. 
NODA (p. 113). 
I cannot help expressing here my regret that in Moda, as well as in so many other 
difficult genera, short diagnoses should have been published of extremely closely allied 
species, which makes their determination impossible without an examination of the 
types ; moreover, there are some species almost intermediate between this genus and 
Chrysodina, either in the structure of the antenne or in the form of the thorax. In 
his general diagnosis of the group Iphimeine, into which Noda enters, M. Lefévre 
gives the anterior femora as armed with a tooth; but this applies only to some of the 
genera in this group and certainly not to Noda. 
The name Noda being preoccupied in Diptera, it has been changed by M. Lefévre 
[Cat. Eumolp. p. 166 (1885)] to Nodonota. 
Noda cretifera (p. 114). 
To the localities given, add :—MExico, Omilteme and Chilpancingo in Guerrero, 
Cuernavaca (H. H. Smith), Michoacan (Flohr); GuateMata, Cubilguitz, Zapote, Dueiias 
(Champion). 
N. cretifera seems to be subject to great variation, and the male insect is conse- 
quently often very difficult to recognize, as it has not the distinguishing curved elytral 
costa of the female. The punctuation of the elytra is always very fine, and arranged in 
more or less double rows; while that of the thorax is variable, though usually very 
fine and close. The elytra of the male insect have a more or less smooth space below 
the shoulders, corresponding to the place occupied by the raised costa of the female. 
The general colour of the upper surface varies from blue to green and violaceous; and 
the tibise, or the entire legs, are as frequently fulvous as they are violaceous. Specimens 
from Juquila, Omilteme, and Chilpancingo are smaller, more robust, and more convex 
than those from the other localities. 
Noda thoracica (p. 116). 
Noda thoracica, Jac.=Spintherophyta cyanea, Lefévre: it must be transferred to 
Spintherophyta.
