78 REV. H. S. GORHAM ON NEW [Mar. 6, 



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

 antennae are not so long. The head is distinctly punct>ired, with 

 deeply impressed but irregularly shaped points, the interspaces being 

 finely alutaceons ; there is a semicircular impression between the 

 bases of the antennie, and two wide fovese 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 ; elytris convexis gibhosis, subtilissime 

 punctatis, hand sti'iatis, macula humerali lunulaque pone medium 

 aurantiacis. 



Long. 15 millim. 



Hab. Philippine 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, niiida, elongato-ovata, thorace utrinque litura fulva, elytris 

 annulo lato humerum subcingente, extus quadridentato, fasci- 

 aque interrupta pone mediutn, parum curvata, utrinque dentata, 

 fulvis. 



Long. 22-28 millim. 



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 obliquely rounded at the 

 apex ; the third joint equal to the three following. 



Tliorax 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 alutaceons, 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.
