Medon incomptus. Sharp. 



A cotype of this species, from Hawaii, is in the South AustraHan Museum. 

 Sharp described the elytra as "in medio transversim obscuratis," and again 

 "with a dark cloud across the middle" ; the cotype has the dark part so placed 

 that it leaves almost the apical half pale and sharply defined, with a part of 

 the base paler than the infuscated portion, but not sharply divided from it. 

 Two specimens from Northern Queensland are structurally identical with the 

 cotype, but differ to a slight extent in the elytral marking, both from it, and 

 from each other. One from Kuranda in the British Museum has the basal 

 two-thirds of prothorax blackish, but apparently from staining. 



Sharp considered the species as allied to the American Lithocharis com- 

 pressa, and that it was "probably a native of some part of the American 

 continent." In the catalogue both species are referred to Ophiomedon, but 

 L. incomptus appears to me to be clearly allied to Medon (Hypomedon) 

 debilicornis. 



Medon, sp. 



Two specimens (sexes) of a species from Queensland (one was taken from 

 a sticky seed of Pisonia brunoniana at Cairns) possibly belong to M. (Chari- 

 chirus) chinensis, Boh.^^^) Structurally the female agrees perfectly with an 

 Indian female, received with the name from Dr. Cameron, except that the front 

 tibiae are rather more dilated to apex. The male has the (apparent ) fifth 

 segment of its abdomen widely and shallowly concave on its under-surface, with 

 the apex conspicuously incurved to middle (the following segments are con- 

 tracted within the body) ; the space between the eyes on the under-surface of 

 its head is densely and somewhat coarsely punctate (on the female the derm 

 there is but finely punctate). The Queensland specimens have the reddish 

 apical part of the elytra fairly wide on each side and narrowed to the suture, 

 instead of dilated there as on the Indian one; so possibly the species is not 

 chinensis, but an allied one. 



In his diagnosis of Charichirus Sharp says, "Tarsi omnes graciles, anteriores 

 simplices" ; but on the Indian and Queensland specimens before me the four 

 basal joints of the front tarsi are dilated so as to be almost twice as wide as 

 those of the other tarsi. 



Medon quadratipennis, n. sp. 



6 ' Black or blackish ; mouth parts, antennae (the median joints infus- 

 cated), palpi, legs, under-surface of head and sterna more or less red, tip of 

 abdomen obscurely reddish. With fairly dense ashen pubescence, sparser on 

 prothorax than elsewhere, and with some rather short hairs scattered about. 



Head between front of eyes and neck rather strongly transverse, sides almost 

 parallel, hind angles scarcely rounded off; with dense and minute ptmctures, 

 sparser (but still dense) and more sharply defined between antennary tubercles 

 than elsewhere. Antennae passing base of prothorax, first joint subcylindrical, 

 slightly longer than second and third combined, fourth slightly longer and thinner 

 than second, and shorter than third, the others to tenth feebly decreasing in 

 length and increasing in width, ninth and tenth transverse. Prothorax feebly 

 transverse, width about equal to that of head, sides slightly decreasing in width 

 to base, with a faint median line ; punctures much as on head. Elytra quadrate ;
