Triplacidea genus novum. 

 Amoiig the Eastern Triplacid- forins are species aaIhcIi froni 

 their resembkmce lo Üie Palaearctic species of Triplax and to 

 the Nearctic Trilomae, are veiy perplcxing to deal witb. Tbey 

 are more ovate thau the true Triplaces, but have (hke some 

 of them) an extremely wide apieal Joint of the maxillary palpi, 

 that Joint being T-shaped. In this respect, as well as by the 

 very faintly widened tibiae, and the more slenderly built antennae, 

 with a more laxly jointed club of three joints, they diverge 

 from the Tritomae as well as from Cyrtotriplax (as restricted 

 by me to the Eastern species with C. Leirisi Crotch for type, 

 that being the oidy species described hx him, when he proposed 

 the name, although he intended it as a Substitute for Tritomci). 

 It will be convenient to take for the type of these insects, which 

 I propose to group under the name Triplacidea, a species met 

 with by Mr. Lewis in Ceylon and which I belicve to bc that 

 discribed by Motschoulsky, Etudes Ent. 1859, p. 107, as ^JripUix 

 melanocephala'-'-, but für which Mr. Crotch in the Revision of 

 the Erotylidae (Cist. Ent. 1876, p. 468) proposed the name of 

 T. Motschulskyi, it having nothing to do with Triplax mehi- 

 nocephala Latr. 



I will therefore here attcmpt the anaiv sis of such of these 

 species as are before me, as far as I am able at this moment 

 to refer them to their proper genera. 



Triplacidea new name — Type Triplax Motschulskyi Crotch. 

 Corpus ovatum, fere ellipticum, modice convexum. Antennae 

 graciles, articulo tertio elono-ato, elava triarticulata, oblonga, 

 articulo octavo brevi, haud transvcrso. Oculi subtihter granulati. 

 Palpis maxillaribus articulo ultimo valde transverso, lato. Pro- 

 sternum haud comprcssum, apice nnitico. Lincae inetasternales 

 perbreves abdominales, ad segmenti marginem iere provectae.
