PAPILIONIXAE : THE GEXUS EUPIIOEADES. 1307 



round at tip; the hoo^ of eighth abdominal se<;mcnl of male liroadly expandins l)ase 

 •ward, the part beyond slender, its extremity siil)spatHlatc ; valves broad ovate, roundly 

 angulate at tip, half as long again as In'oad, armed interiorly with an inferior, arcuate, 

 corneous rod, emitting one or two large, distant denticles on the apical half and at 

 the tip a scries of smaller ones. 



Egg. Nearly a third broader than high, well rounded, the base about half the width 

 of the middle, with no sign of depression at summit; surface clean, witli an exceed- 

 ingly fine cob-web lilie tracery, the floor of the cells nearly smooth. 



Caterpillar at birth. Head furnished with scattered, long hairs, the summit con- 

 cealed by the folds of the first thoracic segment. Body subquadrate, tapering poste- 

 riorly ; thoracic segments with a series of smooth, fleshy tubercles, one to a segment; 

 that of the first, which is much the largest, tapers gradually to a blunt, rounded tip, is 

 directed upwards and outwards and very slightly forward, and is supplied with a few 

 spinous hairs. All the segments of the body furnished with a supralater.al series of 

 small, fleshy warts, one to a segment in a row, that of the eighth abdominal segment 

 being much larger than the others, and those of the second and third thoracic and the 

 first and seventh abdominal next in size ; all bear a collection of what appear like 

 spinous hairs, but which are slightly enlarged at the extreme apex ; there is also a sub- 

 dorsal series of straight, erect hairs as long as a segment, anteriorly placed, one to 

 a segment, on all but those on the second and third thoracic and the first and second 

 abdominal segments seated on excessively minute warts ; there are, f urtlier, suprastig- 

 matal .and iufrastigmatal series of compound tubercles, each with several bristles; 

 last abdominal segment furuislied only with a semicircular fringe of long liairs curv- 

 ing bacl\ward. 



Mature caterpillar. Head moderately large, very well rounded, broadest in the 

 middle, considerably broader than high, the sides broadly rounded, a very little full 

 next the lower part of the ocellar area, the summit broadly rounded and in the middle 

 a little depressed at the suture; considerably deepest next the upper part of the ocellar 

 region, above becoming much shallower; front appressed quite regularly, flat, the 

 sutures a very little impressed ; a slight depression in the triangle at either side below ; 

 triangle fully as broad as high, scarcely reaching the middle of the fi-ont; liead deli- 

 cately corrugated by short, impressed, irregular, transverse lines and on tlie summit 

 and sides behind furnished with a very few. exceedingly short and delicate, very in- 

 conspicuous hairs. Antennae with first joint tumid, mammiform, second very short, 

 third nearly three times as long as liroad, equal and squarely docked, fourth very mi- 

 nute. Ocelli (86 : 2-1-25) six in numljer, four arranged in a strong curve, having its 

 convexity forward and bounded anteriorly by a slightly impressed line, the second 

 from the top equally distant (about its own diameter) from the first and third, the 

 fourth at a little greater distance from the third, a fifth below these, on a line with 

 the third and fourth and as far from the fourth as the latter is from the second ; a 

 sixth behind the arcuate row, at equal distances from the second and fourtli, and 

 forming with them a veiw little less tlian a right angle. Labrum not very large, ratlicr 

 narrow but long, with a deep and broad excision in the middle of the front border, 

 forming a U, half as broad as deep, whose sides are parallel, extending halfway to the 

 base and having its extremities well rounded off. Mandibles pretty large and stout, 

 very broad, the edge straight and smooth, at the upper extremity showing minute, 

 transverse scratches. The outer maxillary palpus with the second joint as long as 

 broad, the third not more than half as broad as the second, but half as long again 

 as broad, the fourth small, conical, rounded; last joint of inner palp apparently 

 like the penultimate of the outer Ijut stouter and shorter. Spinneret moderately large, 

 stout and long, conical. 



Body with a general shape like that of Jasoniades, the swollen anterior portion includ- 

 ing the second and third thoracic and the first and part of the second abdominal seg- 

 tnents, being largest on the terminal thoracic segment ; behind the tumid part the body 

 tapers regularly to the seventh abdominal segment, beyond which it is equal or when 

 the anal prolegs are drawTi forward, the eighth abdominal segment is enlarged some-
