ENTOMOLOGICAL SECTION. XV 



Elytra with confused punctuation. 

 Tarsal grooves long, continued anteriorly parallel with the suture. Thoracic 



channel feeble 11. discoidea. 



Tarsal grooves short, oblique. 



Thoracic channel broad and deep. Surface moderately densely clothed 



with fulvous scales 4. roriilenta. 



Thoracic channel rather feebly impressed. 



Elytra with white scales sparsely placed 10. aiirorata. 



Elytra marmorate with brown and luteous 8. inaculata. 



The species of the third series are as follows : 

 Elytra with convex disc, thorax feebly channeled, antenna! groove long, 



reaching the coxa 9. avita. 



Elytra with depressed disc. Thorax broadly channeled, antennal groove 

 abbreviated posteriorly. 

 Thoracic impression entire, extending from base to apex, hind angles diver- 

 gent 1. obtecta. 



Thoracic impression broad, but basal only, hind angles not divergent. 



Hind angles compressed, pseudo-carinate 2. brevicornis. 



Hind angles not compressed 3. proTiisa. 



The numbers give a better cabinet arrangement and place the species 

 in a series in which their superficial relationships are shown. 



2. — A. BREVicoRNis and PROFUSA are very closely related and may 

 in the future be united. 



5. — A. PYRSOLEPis resembles rorulenta superficially very closely, 

 but Mr. Dike who has the type informs me that the tarsal grooves are 

 as well marked as in sparsa. 



13. — A. modesta Boisd. — A specimen of this species was given 

 nie in Paris, said to have been collected in the Peninsula of California, 

 and as it occurs in Mexico, and shows a tendency to acclimate itself 

 in the warmer countries around the entire globe, it is possible that 

 the locality given me is accurate. For its determination I am in- 

 debted to Dr. Candeze. 



The following changes and synonymy are noted : 



Alaus Lusciosus Hope, should replace gonjojis Leo. 



Cardiophorus Dcjeanii Lee, is an immaculate variety of cardisce 

 Say. 



0. amktus Mcls., appears to be convexus Say. 



C. mimeticus Horn, is a color variety of edwardsi Horn. 



Cryptohypnus nocturnus Esch., and lucidulus Mann., do not seem 

 specifically distinct from bicolor Esch. Other synonyms of this 

 species are already noticed in the Check List. 



C. colon Horn, is a variety of ornatus Lee, with two spots only. 

 It may be entirely black.
