the largest B. fervidus , and the female pupae differ in the same char¬ 
acters as already given for the worker pupae. In this species, as in all 
other bees and wasps, the only external difference between the workers 
and females is that of size. 
The female pupae were all of one and the same size, white and naked. 
Apis mellifica Linn. 
Larva of Worker. —I am not aware that a careful and comparative de¬ 
scription of the larval honey-bee worker has been published. The follow¬ 
ing descriptive comparisons have been made with larva of the bumble bee: 
Closely resembles larva of Bombus , but the body is shorter, broader, 
flatter, with the head less prominent than in Bombus. The body is much 
rounded towards the head and abdomen, tapering very equally at both 
ends; the segments but slightly convex, while the lateral region is less 
prominent than in Bombus , less so than usual; and the posterior por¬ 
tion of the segments is less thickened than usual. On the anterior part 
of the back (tergum) of each ring is a broad sublunate area, behind 
which, and especially on the sides, the ring becomes more convex. The 
tip of the abdomen is subelliptical, being round, but longer than broad; 
the tergites and sternites not well marked. It, however, resembles the 
larval Bombus quite closely. Genitals well marked on eighth ring at 
front edge, appearing as two minute parallel slender tubercles, also a 
pair on the ninth and tenth segments less distinctly marked, but a little 
larger. The head is of about the same proportion to the rest of the body 
as in Bombus; it is a little longer than broad, the front not very con¬ 
vex. Eye-ring not very full. The median line between the eyes is 
deeply impressed. The antennae each form a deeply depressed minute 
tubercle on each side of the base of the clypeus. Supraclypeal area in¬ 
distinctly marked. The clypeus is square, as long as broad, much 
longer and narrower than in Bombus. The labrum is broad, bilobate, 
covering the ends of the mandibles; broader and more transverse than 
in Bombus. The maxillae are rather slenderer than usual, subacute, 
ending in a minute acute spine. Labrum as usual, ending in a slightly 
chitinous transverse ridge. Mandibles cylindrical, acute, ending in a 
single point, more fleshy, and more like the maxillae than usual. 
Position of Larva _It is doubled on itself in the bottom of the 
cell, being more doubled than in Bombus , and with a softer, thinner 
skin. The cell of the semipupa is closed over, and the body of the latter 
is elongated and extended along the length of the cell. There is nothing 
in the shape of the larva to justify the inference that Apis is not a higher 
genus, more specialized, than Bombus.
