4oG ^Ii'- G. J. Arrow on new 



Melolonthidae. 



The name Dejeania lias been used in tliree different 

 orders of Insects, the genus having the priority belonging to 

 the Diptera. Tiie Coleopterous genus should be called 

 Dichelomorpha, that name having been given by Burmeister 

 to a Cbinese species [Dichelomor2^ha ochracea) placed by him 

 among the Hopliinae, but allied to the insect I have described 

 in the present paper. The type of Blanchard's genus 

 [Dtjeania ahiosn) is an insect of very different appearance, 

 but these extreme forms are linked together by the new 

 species {D. lineata, Arrow) and others described and un- 

 describedj and all may best remain in one genus until the 

 time comes for a comprehensive study of them.

Phceochroops gi'gas, sp. n. 



P. indico proxime affinis, major, minus grosse punctatus ; prothoracis 

 lateribus baud denticulatis, vix arcuatis, medio leviter angiilatis, 

 angulis posticis magis acuminatis, eljtrorum costis paulo la;vi- 

 oribus, magis elevatis ; abdomine magis rugoso ; tibiis 4 posteri- 

 oribus baud transverse carinatis. 



Long. 15 mm. 



Ilah. Borneo, Pengaron ; Perak. 



Specimens were found by Mr. Doherty in both the above 

 localities. They closely resemble the new Indian species, 

 but are larger, tbe puncturing of the upper surface is a litt'e 

 less dense, the prothorax is less uniformly curved at the sides, 

 which are not denticulated, and the hind angles are more 

 evident. The elytral coslse are a little more elevated and 

 the hind tibise are not interrupted at the middle of the outer 

 edge by a transverse carina. 



Phceochroops acuti'coUis, sp. n. 



Statura prsecedentium eed opacior, rugosius punctatus, magis regu- 

 laiiter setosus ; prothorace cmnino crtbre punctato-rugoso, 

 lateribus distiucte elevatis, fere rectis, angulis posticis paulo prc- 

 ductis; eljtris densissime punctatis, singulo fortiter tricostato, 

 costis laevfbus, sat parce mfo-setosis ; tibiis 4 posterioribus baud 

 transverse carinatis, posticis gracibbus. 



Long. 14 mm.

A single specimen found by Mr. Dolievty is in the British 

 ]\lnpeum collection. It is more densely sculptured than either 

 of the preceding species, tbe hind angles of the prothorax are
