 tathorax sequalis haud impressus ; pedunculus abdominis antice 

 subtruncatus, postice latior angulis lateralibus posticis rotun-

 apicem subacute angulo prominente versus medium lateris in- 

 terni denteque parvo paullo sub apicem, spatio inter angulum et 

 dentem subapicalem subserrulato. 



Long. corp. lin. 4r§. 



In Mus. D. C. C. Babington. In saccharo detecta. 



Individuum alterum etiam in saccharo detectum differt statura 

 minori, lineas 3^ longitudinis tantum habens, colore obscuriori 

 sc. testaceo-fulvo ; dente mandibularum subapicali magis pro- 

 minenti angulo medio tamen fere obsoleto, canali faciei nisi inter 

 carinas frontales obliterata. 



Typhlopone Shuckardi. 



Testaceo-fulva nitida tenuissime punctatissima ; capite lateribus par- 

 allelis, postice valde emarginato fronte carinata et canaliculata 

 ut in T. fulva ; antennis piceo-castaneis 11-articulatis articulo 

 ultimo duobus preecedentibus paullo majori, mandibulis piceo- 

 castaneis apice nigricantibus, dente subapicali minuto et obtuso 

 vix prominente ; metathoracis dorso canaliculato ; pedunculo 

 abdominis subtus versus basin in hamum brevem acutum pro- 

 ducto, abdominis apice 5-denticulato, denticulis lateralibus ma- 

 joribus. 

 Long. corp. lin. 5. 

 In Mus. nostr. Communic. D. Raddon. In saccharo detecta. 



Typhlopone Dahlbomii. 



Pallide lutea, mandibulis obscurioribus ; nitida tenuissime puncta- 

 tissima, capite lateribus subparallelis postice vix emarginato 

 impressionibus duabus frontalibus magnis rotundatis in quas 

 insident antennae breves clavatse ll-articulatse articulo ultimo 

 maximo (praecedentibus 5 majori) ; impressionibus carina media 

 tenui antice dilatata separatis ; canali omnino obsoleto, mandi- 

 bulis apice acutis dentibusque duobus magnis et acutis intiis
