Distinguished at first sight from the preceding by having the 
thorax exactly truncated at the base; the sides of the thorax and 
elytra more thickly clothed with subelliptical shining silvery- 
white scales, and by being without erect hairs ; the upper surface 
is frequently glabrous. 
I have many times taken this insect in the north and south of 
England, invariably on the common heath (Calluna vulgaris), in 
June and October.

Trogon melanocephalus, Gould (male). 
Lenets of intestine from gizzard to ceca seven inches. Length of 
ceeca one inch two-tenths. Length of rectum two inches four- 
tenths. Ousophagus large at its upper extremity, contracted in the 
middle, but at its lower extremity expanded into a proventriculus, 
measuring nearly one inch in length and four-tenths in diameter 
when inflated ; stomach round and slightly flattened. Epithelium 
longitudinally rugose, not hardened, extending slightly into the pro- 
ventriculus. Intestine of large diameter for the size of the bird; 
rectum only slightly larger than the lower end of the small intestine. 
Ceca small at their junction with the rectum, and at about half their 
length expanding into a sac. Cloaca small, the membranes thick- 
ened. ‘Trachea simple, acted upon by one pair of sterno-tracheal 
muscles only. Bronchiz of large diameter in proportion to that of 
the trachea. ‘Tongue arrow-shaped, four-tenths of an inch long, 
armed with a strong spine on each side at the base, and with nume- 
rous smaller ones scattered round the epiglottis. The stomach and 
cesophagus were filled with hard seeds about the size of a pea mixed 
with a pulpy matter. 
The sternum is very broad in proportion to its length; it is nar- 
rowest at the junction of the ribs, where it measures half an inch in 
breadth. The anterior margin is narrower than the posterior; at the 
former it measures seven-tenths of an inch in breadth, at the latter 
one inch. The total length of the sternum including the manubrial 
process.is one inch; The posterior margin is indented on both sides 
with two deep and wide fissures, the exterior ones largest. ‘The 
keel is four-tenths of an inch in depth, much arched on its inferior 
margin, and with its anterior one much scolloped; it extends quite 
to the hinder edge of the sternum, The manubrial process is long 
and strong, somewhat deflexed and triangular. 4
