however, are very much more distinctly punctate-striate, and the 

 antennae are not so long. The head is distinctly punctured, with 

 deeply impressed but irregularly shaped points, the interspaces being 

 finely alutaceous ; there is a semicircular impression between the 

 bases of the antennae, and two wide foveae behind. The mentum is 

 wide and but little rounded, subtruncate in front. The thorax is 

 rather longer than wide, of nearly equal width in front and behind, 

 varying in this respect probably sexually ; both front and hind angles 

 are acute, but not much produced. The elytra have the striae 

 arrested on the yellow spots, and the basal ones are a little tumid. 

 The underside is scarcely punctured ; but the prosternum is very 

 finely transversely wrinkled. I have seen this species in the British 

 Museum. 



6. Hybosoma tetrastictum. 



Nigrum, nitidissimum,omnino confertim subtiliter punctatum,antennis 

 thoracem hand superantibus ; ehjtris convexis gibhosis, subtilissime 

 punciatis, hand striatis, macula humerali lunulaque pone medium 

 aurantiacis. 



Long. 1 5 millim. 



Hab. PhiUppine Islands, Leyte (Semper). 



This species is allied rather closely to both those preceding, but 

 has no trace of striation, and the elytra are more inflated behind the 

 middle than in either of them. The thorax is slightly narrowed 

 behind, so that both the basal and front margins are narrower than 

 the middle. The sculpture of the underside is similar to that of 

 H. striatum. 



I have only seen two specimens — the one in my own collection, 

 which I consider referable to this species, taken in the island of Leyte, 

 and one which I obtained from Mr. Higgins, but without any other 

 locality than Philippine Islands. 



7. Megalodacne iMPERATRix. (Plate XVIII. fig. 8.) 



Nigra, nitida, along ato-ovata, thorace utrinque litura fulva, elytris 

 annulo lata humerum subcingente, extus quadridentato, fasci- 

 ague interrupta pone medium, parum curvata, utrinque dentata, 

 fulvis. 



Long. 22-28 milhm. 



Eab. S.E. Africa, Mamboia. 



Head and thorax very finely punctured, the base of the head more 

 sparsely and deeply so ; club of tlie antennae obhquely rounded at the 

 apex ; the third joint equal to the tluee following. 



Thorax transverse, front and hind angles acute but not produced ; 

 a triangular fossa on each side of the base is rugose; the surface 

 between the scattered punctures is finely alutaceous, sides finely 

 margined, as is the base as far as the I'ossa. Elytra with three or four 

 series of punctures visible at the base. Prosternum keeled but not 

 acutely, nor produced in front, not punctured, but finely wrinkled 

 throughout.
