600 Mr. G. J. Arrow on the genus 



et extra carinas pilis longioribus vestitis, antermis (quam corpore, 

 £ longioribus, 9 brevioribus) articulis omnibus elongatis, secundo 

 quam tertii dimidio longiore, quarto et sequentibus subsequalibus ; 

 pectore nudo, prosterno postice transverse strigoso, meso- et meta- 

 sterno grosse punctatis, abdomine subtus pubescente, segmentis 

 secundo, tertio et quarto medio bi-impressis. Long. 6'3 mm. 



Hab. S.W. India, N. Kanara (H. E. Andrewes). 



This is the first species as yet described from India 

 proper, although H. spinicollis and H. few have been 

 received by M. Oberthiir from Bootan. It closely re- 

 sembles H. puberula, Reitt., and H. fallax, Grouv., but is 

 larger than either and considerably larger than the first, 

 while it has not the deep impression and tuft of hairs upon 

 the head stated by M. Grouvelle to characterize the male 

 of H fallax. Although the relative length of the joints 

 of the antennae, which afford one of the most positive 

 means of identifying these difficult species, is not described 

 in either of those mentioned, if my identification of them 

 is correct they are both characterized by nearly equal 

 second and third joints, the remainder progressively in- 

 creasing in length to the end. In the new species the 

 third joint is considerably longer than the second and 

 slightly longer than those following, which are of equal 

 length. 



H. pallida, sp. n. 



Valde depresssa, pallide testacea, capite prothorace antennisque 

 rufo-flavis ; capite prothoraceque crebre punctatis, hoc paulo trans- 

 verso, lateribus fere rectis, lsevissime crenatis, angulis anticis minute 

 bidentatis, posticis paululo contractis, disco costis duabus lateralibus 

 fere parallelis instructo ; scutello punctato ; elytris striato-punctatis, 

 lateribus acute carinatis ; antennis quam corpore longioribus, scapo 

 gracile, recto, articulo secundo longitudine ad tertii dimidio asquali. 

 Long. 8 mm. 



Hab. S. Madagascar, Fianarantsoa. 



This is a species closely allied to H. atrata, Grouv., 

 which was also found in the same locality, but much 

 lighter in colour than that or any other known Madagas- 

 can form. The prothorax is rather shorter and its lon- 

 gitudinal costse more pronounced and straighter. The single 

 type specimen, found by the Rev. W. D. Cowan, is a male, 

 and has the conspicuous, strongly-curved prolongation of 

 the mandibles distinctive of that sex in this section of the
