height of the tree below the branches, and found in 

 clusters of four and five together." 



On inspecting these figs after their arrival it was 

 evident that a portion of the inmates had already effected 

 their egress, though some of the females had died when 

 in the act of emerging from the seed-vessels, several of 

 the apterous males, together with a few of their winged 

 partners, still adhering to the glutinous orifice of the 

 passage whereby others of the brood had escaped, this 

 being the first instance on record in which any of the 

 former have been known to quit the fig. Both sexes are 

 smaller than the European Blastophagce ; the males have 

 an obcordate head, with short six-jointed antennae pro- 

 jecting from the clypeus ; then- broad trigonate mandibles, 

 bidentate at the apex, forming, when closed, a transverse 

 prominent line in front, and their eyes conglomerate 

 within black triangular maculae (as seen in balsam slides). 

 The males are remarkable as having only four developed 

 legs, the middle pair being obsolete. Traces thereof have, 

 however, been detected under the microscope, in a very 

 rudimentary form, not otherwise perceptible, in some 

 transparent specimens mounted in balsam, consisting of 

 two Particulate appendages, of minute dimensions, which 

 may be detached in dissected specimens, and which are 

 shown in their natural position, affixed to the posterior 

 margin of the mesosternum, in Plate III., fig. 47. When 

 viewed laterally, as in fig. 32, these quadrupedal males, 

 standing on their short robust legs, with projecting head, 

 are somewhat suggestive of a miniature pachyderm — si 

 parva licet componere magnis. 



The pronotum is very large, rounded in front and 

 deeply emarginate at the base, with long projecting 

 angles directed backwards ; the mesonotum is semi- 

 circular and broadly truncate behind ; the metanotum 

 is longer than wide, narrower and truncate behind, 

 with the sides rounded. The legs have their femora 

 much distended ; those of the first pair are longer and 

 broader than those of the hind legs ; the tibiae of the 

 first are very short, and as wide as long, terminating in 

 two incurvate spines forming a large crescent ; their 

 tarsi are Particulate and robust, with large prominent 

 claws ; the hind tibiae are longer than the fore tibiae, 

 narrow at the base and truncate at the apex, with two 

 short spurs at each angle and three or four sharp teeth 

 near the apex on the outer margin ; their tarsi are 5-
