This species is absolutely cosmopolitan and exists in swarms, 

 under artificial conditions, in almost every part of the world. It 

 is numerous in collections from all parts of tropical Asia, and if 

 this is not its original home, it has at least become very effec- 

 tually naturalized. It varies to some extent in intensity and 

 shade of colour, as is to be expected, and consequently has been 

 described under a variety of names, but they are all here referred 

 with little hesitation to the same species. 



De Bormans placed tliis species in Aiyteryglda, but its affinities 

 are entirely with Labia, ia which Gerstajcker and Scudder placed it. 

 De Bormans maintains that the second tarsal segment is lobed, 

 but this structure is so minute that it cannot be regai'ded as a 

 true bilobed forficuline tarsus.

(Scudder suggested the name Lahidophora, as he considered 

 Platylabia to resemble too closely P/(//^/7rt6«s,"\Vesmael, in Hymeno- 

 ptera ; but of course this objection does not stand, and Dohrn's 

 original name holds good.) 



Antennae with 10-13 segments ; third segment elongate and 

 subclavate ; fourth almost as long, ovate or pear-shaped ; the rest 

 ovate or elongate pear-shaped. Head depressed but smooth, 

 sutures obsolete. Pronotum narrower than the head, more or 

 less narrowed and convex anteriorly ; sides parallel and hinder 

 margin rounded. Elytra very flat and well developed. Wings 

 prominent. Legs moderately long ; first and second tarsal seg- 

 ments about equally long. Abdomen strongly flattened, elongate, 

 parallel-sided, lateral glandular folds not present. Last dorsal 

 segment ample, subquadrate, smooth. Penultimate ventral seg- 

 ment ample, rounded. Pygidium generally prominent in both 

 sexes. Porceps elongate, variously armed ; those of $ also 

 elongate, generally dilated or laminate. 



Range. Oriental Eegion. 



Allied to Labia ; differs in the strongly flattened body and the 

 obsolete lateral abdominal folds ; the pronotum is narrowed 

 anteriorly, the fore-border being almost produced into a neck.
