Description of Neiv 



the second joint of the maxill. palpi exhibiting nothing un- 

 usual &c. As to the species which I have established, I feel 

 very certain that they are new and good ones, as it would 

 appear from the quotations in " Lacord. Gen. d. Col." that 

 since Dejean's descriptions no new ones of Indian species 

 have been published. 



These insects live in the manner of the European Feronidse, 

 but appear to affect rather damp localities, some of them 

 take freely to their wings and fly commonly into houses in 

 the evenings during the rainy weather. 



42. Distrigus costatus. N. 



D. nigerrimus, nitidus, subtilissime parce punctulatus, ore pedibusque 

 piceis, tarsis antennisque castaneis, palpis brunneo-testaceis, long. corp. 

 4| lin. 



Capite clypeo fronteque leviter excavatis, hac impressionibus 2 later- 

 alibus semilunaribus profundissimis rugulisque nonnullis transversis; 

 mandibulis fortiter sulcatis ; menti dente magno excavato ; thorace lon- 

 gitudine parum latiore, breviter obcordato, lateribus rotundato, basin 

 versus angustato, basi truncato medio leviter emarginato, antice lateribus 

 fortiter deflexo, dorso posticeque piano, basi longitudinaliter profunde 

 2-impresso, inter impressionibus leviter transversim rugoso, admarginem 

 ant. et post, obsolete sulculato, dorso rugulis nonnullis transversis subtil - 

 ibus, linea med. longitud. subtili extremis profundis diviso; elytris 

 profunde striatis, interstitiis fere planis, puncto ad striam 2m medio ob- 

 solete ; tarsis dorso fortiter 3-costatis; prosterno piano. 



Sub quisquiliis in ripis lacus Colombensis communis. 



Apparently closely allied to D. impressicollis Dej. How- 

 ever, if the description given in the Spec. gen. embraces all 

 the characteristics of this latter spec, mine is undoubtedly 

 different from it. Dejean says nothing about the costas on the 

 back of the tarsi which are the principal characteristic in my 

 spec, nor are such costae of general occurrence or of so little 

 importance that it could be supposed they had been left
