The study of additional material obtained by Herr 

 Hoge has led me to conclude that two distinct though 

 very similar and closely allied species were included in 

 my description of D. ruhcns. They are distniguishable 

 as follows : — 



D. rubens.—Wigra, thorace supra et elytris coccineis, iilo antice 

 et postice nigro-marginato, his basi vittaque suturali nigris. 

 Thorax grosse confluenter punctatus, disco pauUo insequaU hand 

 distincte calloso ; elytris apice flexuoso-truneatis, angulis exterion 

 et suturaH distinctis acutis. Hab. Mexico. I have before me 

 one example only, a S' • 



D. tuherculicoUis, n. sp.— Nigra vel piceo-nigra, pedibus saepe 

 fulvo-piceis, thorace supra coccineo antice et postice nigro-margi- 

 nato, elytris fulvis vel rufescenti-fulvis— in ^ unicoloribus, in ? 

 vitta sutm-ali fusco-nigra. Thorax gi-osse confluenter punctatus, 

 disco tricalloso callo posteriori oblongo impunctato nitido. Elytra 

 apice obtuso flexuoso-truncata, angulis obtusissimis. Hah. Mexico, 

 Tupataro in Guanajuato {Huge), and Mexico City. 



Mctalepus comis, n. sp. (PI. VII., fig. 9, c? ). 

 Minor et gracilior, opacus, dense erecte sericeo-griseo- (capite 

 prouotoque nigro-) pubescens ; cajrulescenti-niger, elytris fascia 

 basali (versus scutellum angustata et supra epipleuras dilatata), 

 abdomine dimidio apicali, pedibusque l«te rufis, tarsis et interduui 

 tibiis in medio fusco-nigris. Caput in^quahter punctatum, ante 

 oculos multo magis quam in M. angulato (Chevr.) elongatum. 

 Thorax in medio angulato- dilatatus baud vero dentatus, sat grosse 

 subalveolatim punctatus. Elytra subtilius sat dense punctata, 

 ad apicem obtuse flexuoso-truncata, fere irregulariter rotundata sed 

 angulis externis dentatis, disco lineis tenuibus subtevibus plus 

 minusve distinctis. Subtus longius griseo-pubescentis, abdomine 

 (basi et marginibus longe piibescentibus exceptis) polito vix 

 sparsiin punctulato. Antenna? et pedes graciUimae, ilia? ^ corpore 

 duplo longiores, 12 articulataj, ? corpore brevioribus. Long. 10— 



14 miUim., ^ ? . 



Variat abdomine toto mctasternoque medio liEte rufis. 



Ilah. Mexico, Iguala in Guerrero (Iloije). 



Appears to be nearly allied to M. hated (Horn), from 

 Arizona. Dr. Horn has rightly corrected me as to the 

 nature of the terminal segment of the antenna ni Meta-
