180 Mr. J. F. S. Parry on some 



comparing these together, I can only perceive differences in the 

 feet, palpi, &c., which appear rather to be specific than sexual. 

 The A Eschscholtzii is a larger insect than P. Dejeanii, its legs 

 and antennae are relatively rather longer and more slender, the 

 elytra are larger in proportion and more elongated, and the punc- 

 tures of the striae are a trifle more distinct ; the thorax moreover 

 is less distinctly punctured on the hinder part. The eyes are 

 very prominent, and there is a mesial fovea on the forehead, and 

 an irregular depression on either side near the insertion of the 

 antennae. The thorax is broader than long, and rather suddenly 

 dilated in the middle ; the anterior angles are produced and ob- 

 tuse, the posterior angles produced laterally, and acute ; the lateral 

 margins somewhat reflected, and the reflected portion very broad ; 

 the disc convex, and with a deep mesial groove, terminating pos- 

 teriorly in a fovea, and there are two largish shallow fovea behind, 

 one near each angle, in which are some scattered punctures, as 

 there are likewise near the anterior angles of the thorax : the 

 posterior margin is produced in the middle, in the form of a large, 

 and nearly semicircular lobe. The scutellum is minute and 

 pointed. The elytra are moderately convex, and have a narrow 

 reflected margin : they are rather delicately punctate-striated ; of 

 a brilliant copper colour, with green-blue margin. The thorax is 

 steel blue, and the remaining parts are black, with a faint blue 

 tinge. The whole insect is exceedingly glossy. 



Genus Physocrotaphus. 



A new genus belonging to the section of Tnmcat'ipennes, and 

 allied to Crjmindis, distinguished by a large head, swollen behind 

 the eyes, combined with long and somewhat slender antennae, 

 elongated palpi and jaws (the former with the terminal joint by 

 no means securiform), and simple tarsi and claws. 



Physocrotaphus Ceylonicus, ^. (Plate XVIII. fig. 1). 



Phys. niger, nitidus, antennis pedibusque piceo-testaceis, thorace 

 cordiformi, postice truncato, foveis duabus impresso, mar- 

 ginibus lateralibus reflexis. Elytris striatis, striis leviter 

 punctatis, interstiis punclulatis. 

 Long. Corp. 7 lin. 

 Habitat Ceylon. 



The above described species appearing to me to bear much 

 resemblance to an insect described (from Mr. Melly's collection) 

 by Mr. Westwood in the fourth volume of our Transactions, I
