Descriptions of three new species of Tjuciiopterygia, found by 

 the Rev. T. Blackburn in the Sandwich Islands^ by the Rev. 

 A. Matthews, M.A. 



To receive Trichopterygia from the Saudwicli Islands is a 

 great event \w Entomology, and the present species wonld lead 

 one to supj)f)se that the fanna of tliat region mnst be of an 

 abnormal and highly interesting type, since they are all more or 

 less aberrant from any previously known forms. They were all 

 found ])y INIr. Blackburn hi the neiglibourhood of Honolulu, and 

 were sent by him to Dr. iSharp, who veiy kindly })resentcd them 

 to me. 



J\Ir. Blacklnn-n deserves much credit for the care with which 

 these insects had been mounted, their form and limbs being 

 clearly displayed. I hope that he will persevere in his reseai'ches, 

 and soon tend home a fresh and more numerous collection.
