MIMETICA CRENULATA, new species. 



Ti/pe. — Male; Turrialba, Costa Rica. (SchildandBurgdorf.) [Cat. 

 No. 9478, U.S.N. M.] 



This species is apparently allied to J/, hrunneri Saussure andPictct, 

 but can be readily separated by the crenulato-lobate distal third of the 

 caudal margin of the tegmina, the blunter apex of the same, and the 

 more deeply rounded and sharply defined emargiiiations of the cepha- 

 lic margin. As the males of several species of the genus are unknown, 

 this may possibly represent the opposite sex of a species already 

 known. However, none of the species known only from the female 

 approach this form in the character of the tegmina except J/, siihin- 

 tegra Saussure and Pictet, which is a much larger insect with a some- 

 what different venation. 



Size, medium; form compressed, as is usual in the genus; surface, 

 tuherculato-rugose. Head distinctly fiattened cephalad; vertex hori- 

 zontal; fastigium but little produced, rectangulate, longitudinally sul- 

 cate; facial fastigium acute; antennjv henvy, margin of the scrobes 

 touching on the dorsal half of the internal niart>ins. the fastii»"ium of the
