EURYBATUS INEXPËCTATUS. 135 



NOTE XVII. 



DESCRIPTION OF THREE NEW SPECIES OF 

 MALAYAN LONGICORNIA. 



C. RITSEMA Cz. 



Euryhatus i7iexpectatus ^ nov. spec. 



This species is closely allied to Euryhatus novempunctatus 

 Westw. '), but easily distinguished by the different arma- 

 ture of the antennae, these having not only the 3rd — 5th 

 joints spined at the end , but the 6th joint too is provided 

 with a spine which , inter alia , is more distinct than that 

 on the 5th joint in novempunctatus. 



As regards the coloration it agrees with novempunctatus, 

 but the pronotum is unspotted and the tubercle which in 

 novempunctatus proceeds from the lateral black spots is 

 entirely wanting ; the four anterior elytral spots are rather 

 small and round , the two posterior ones large and trans- 

 verse , rather narrowly separated at the suture but reaching 

 the thickened lateral margins ; moreover the apical margins 

 are broadly bordered with black ; underneath the distribution 

 of the colours is exactly the same as in novempunctatus. 



The punctuation of the head is considerably finer and 

 wider apart than in the allied species , and the sculpture 

 on the scape of the antennae less rugose; the 3rd and 4th 

 joints of the antennae are straight, the 3rd — 6th joints 

 armed at the end with an acute spine which is strongly
