Ö'2 STROBIDERUS. 



amongst the Galerucidae, will easily distinguish this genus 

 from the rest of the Monoleptinae in which it must be placed 

 by the characters pointed out above, although the general 

 shape of the insect is more elongate than is generally the 

 case in this division. 



Strohiderus excavatus , n. sp. 



Elongate , pale fulvous. Thorax extremely finely punct- 

 ured. Elytra strongly punctate-striate with convex inter- 

 stices, fulvous, pubescent, the apex black, excavated and 

 produced (cf). Female with simple elytra. — Length 2^/3 

 lines. 



Head impunctate , the vertex with a transverse blackish 

 band. Eyes very large , black , the space between them 

 somewhat depressed towards the lower portion. Antennae 

 as long as the body, all the joints, with the exception of 

 the very short second one, slender, of equal length and 

 very elongate, covered with rather long hairs. Thorax 

 twice as broad as long, rather convex, sides rounded, the 

 anterior angles entirely obsolete , the posterior ones acute , 

 surface extremely finely punctured , slightly wrinkled. Ely- 

 tra closely covered with yellow pubescence , deeply and 

 regularly punctate-striate , the interstices longitudinally 

 costate , fulvous , the extreme apex black. The latter pro- 

 duced in a spoonshaped protuberance at each elytron , 

 proceeded by a deep excavation or hole extending into the 

 elytra. Legs slender , first tarsal joint as long as half the 

 tibia, the latter with a long spine. 



In the female the antennae are shorter and the elytra 

 are slightly truncate at the apex. 



A male and a female have been taken in the District 

 of Rawas (Sumatra-Expedition). 



Glyptolus , nov. gen. (Sect. Scelidinae). 



Body elongate, parallel. Head exserted. Eyes large, en- 

 tire. Labrum broad, entire. Palpi slender, the last joint
