DiAPHANES, Mots. Etud. Ent. i. 44. 



Though very close to Laminjris, this genus has a parti- 

 cular facies of its own, from the elevated margins of the 

 thorax and wider elytra. The eyes are very large, even 

 more developed than in Lampyris or Lamprorliiza, the 

 abdomen not so acutely lobed as in the former, the 

 fifth and sixth segments with transverse luminous spots. 

 The species appear to be Indian or Malayan, but some of 

 the African might be introduced, e.g., margin'vpennis, 

 Boh.; but as most of them are true Lampyrides, I prefer 

 keeping this for the Eastern species. 



Diaphanes indicus, Mots. 1. c. iii. 15. 

 India; Mus. Brus. c?. 



Diaphanes Ihribatus, n. sp. 



Sub-parallelus, opacus, fuscus, thorace testaceo disco in- 

 fuscato, margine antico fortiter reflexo, litura submarginali 

 diaphana, elytrorum limbo toto, pectore, femoribus infra, 

 abdominisque apice flavis. 



Long. lin. 7—10. <S . 



Mas. — Oculis magnis, pygidio apice leviter bisinuato, 

 segmento septimo ventrali apice rotundato, integro. 



Head fuscous, eyes as in Lampropliorus. Antennae 

 scarcely longer than the head itself, fuscous ; their basal 

 joint large, rather paler, the second very short, the suc- 

 ceeding ones longer than wide, setose, obliquely truncate, 

 the two before the apical shorter, but not transverse ; 

 thorax elongate hat-shaped, the lateral and front margin 

 reflexed ; the disc convex, with a fine carinate line from 

 the base to the apex, Avhich with the sides is yellow, 

 as Avell as the base itself narrowly ; the elytra are smoky 

 fuscous, with the suture and lateral margin very nar- 

 rowly yellow. Thighs above, tibite, tarsi, and abdomen 

 fuscous, wath the exception of two luminous transverse 

 spots on the fifth and sixth segments, the apex of the 

 pygidium, and seventh or apical segment, which are 

 yellow. The thorax has tAvo diaphanous spaces at the 

 front, which are almost joined, and which are quite trans- 

 lucent, so that the head can be seen through from above.

Diaphanes guttatus, n. sp. 

 Niger, supra testaceus, thoracis disco ad basin, elytrisque 

 vittis duabus, paulo distinctis, fuscis.
