276 Mr. C. J. Gahan on new Longicom Goleoptera 



male long, and produced on its outer side into a spur. 

 Smaller than longicornisj Thorns., and distinguished, inter 

 alia, by the long spines to the eljtra. 



Cyriocrates Waterhousei, n. sp. (PI. XVI. fig. 4.) 



Niger, squamosa pubescentia viridi-caerulea ; prothorace supra 

 sequali, macula longitudiuali nigra subdepressa media ; elj^tris ad 

 basin grauulis parvis, nigris, maculorum nigrorum tribus seriebus 

 transversis ; antennia $ corpora pauIo brevioribus, articulia basal- 

 ibus Yiridi-caeruleis, c?oteris nigris. 



Long. 27 mm., lat. 11 mm. 



If ah. Nias Island. 



Excepting a longitudinal black spot on the thorax and three 

 (or four) series of spots on the elytra, tlie body is entirely 

 covered with a bluish-green squamous pubescence, somewhat 

 iridescent on parts. Head^ including the labrum and base of 

 the mandibles, entirely bluish green, with a very faint longi- 

 tudinal median line on the face and vertex. Antenna in 

 the female a little shorter than the body ; the scape, second 

 joint, and bases of the third and fourth joints blue, the rest 

 black. 



Prothorax with strong and sharp lateral spines ; tlie disk 

 smooth. 



Elytra with some small black granules at the base, with 

 three transverse, somewhat anteriorly curved bands, each 

 made up of eight quadrate black spots. (In a second speci- 

 men there is a fourth indefinite band, which may have been 

 due to rubbing.) From each of the minute and scattered 

 punctures of the elytra there springs a short black hair ; these 

 hairs, of which there are a few also on the prothorax, are only 

 visible when looked at sideways. 



Legs coloured like the rest of the body ; the middle tibise, 

 fringed, like the posterior, with black hairs on their lower 

 outer border, are but very faintly emarginate. 



In colour and markings resembles Monohammus Boioringiy 

 "White, but is otherwise very distinct. 



I have named this fine species after my colleague, Mr. C. 

 O. Waterhouse, to whose help and guidance I owe much.
