Fam. EROTYLID^. 

 Subfam. LANGURIIDES. 



Fatua Dej. Gat.; Crotch, Rev. Erotyl., 1876, Gist. Ent., I, p. 382. 

 (Macromelea Hope.) 



The species o? Fatua are little understood, and owing to the too 

 bi'ief descriptions, and neglect of important characters are confused 

 in Crotch's Gatalogue. In tiie typical species M. longicornis Wied., 

 the antenna3 are very much longer in the tnale than in the female; 

 the thorax is narrower, and more distincllyso especially in front; 

 the legs are longer in that sex, though not very noticeably, and the 

 front tibise are roughened, inside, with numerous sharp denticules, 

 much as they are iu Dasydactylus and in Languriosoma. The pecu- 

 liarity of the three terminal joints of the antennse is striking, the 

 eighth joint in the maie is compressed and a Utile distorted, the 

 three succeeding it are very short, the apical joint very small and 

 compressed; the same structure occurs in the female but the eighth 

 joint is much shorter and obconic. Fatua Sealyi of Crotch's collec- 

 tion is the maie and Fatua crassa the female of F. longicornis accor- 

 ding to the examination of the types which I made sometime ago. 

 M. Crotch was mistaken in supposing the example of F. Sealyi to 

 be a female, 



With regard to F. nigripennis I can express no opinion, Crotch 

 had not seen it. According to the Munich Gatalogue it is the 

 female oi Fatua longicornis Wied.; F. Lambii Crotch, loc. cit. The 

 description gives one no due to the sex, or relative length of the 

 antennte, and as the following species is from India, and has no 

 Interstilial punctuation I shall treat it as distinct. 



Fatua Andre"wesi n. sp. — F. longicornis similis et affînis, 

 minor nigra, nitida; capite prothoraceque rufis, subtiliter et perob- 

 solete punctatis, elytris subcœruleis tenuiter distincte punctato- 

 striatis, interstiliis sublsevibus; antennis (maris) corporis dimidium 

 superantibus, (feminœ) brevioribus; articuhs tertio ad octavum 

 elongatis, apicibus crassioribus. — Long. 15-18 mill. (^fÇ. 



Hab. India, Pollachi near Anamalais Hills. Flying over the road. 



The chief distinctioji to be observed in this insect, is the relative 

 shortness of the antennes, compared with those of F. longicornis. 

 In my examples of that species the antennaî are fully three-quarters 

 of the lenglh of the whole insect, the joints 3-8 being very much 

 longer than they are in F. Andrewesi; this might be due to the 

 smaller size, but at the same lime the three terminal joints are 

 not longer than wide, whereas in F. lo)igicornis, they are distinctly 

 longer and the thorax of the maie is less conical in front.
