38 Mr. D. Sharp on some 



legs are yellow, the femora iufuscate, with their base 

 yellow. 



The species is closely allied to F. flavocincAa, Kr. 

 (Ceylon), and F. fovea. Sharp (Japan); it is still closer, 

 however, to an undescribed species found by Mr. Lewis 

 in China, but I think is nevertheless a distinct species : 

 there is also a very closely-allied species in Brazil. 



Occurs rarely near the town of Honolulu, and is pro- 

 bably an introduced species. 



Tachyusa j^umila, n. sp. Parva, depressa, fusco 

 testacea, abdomine nigro-fusca, antennis pedibusque tcs- 

 taceis ; subtilissirae punctulata et pubescens, subnitida ; 

 capite brevi, posterius recte truncato; prothorace margine 

 anteriore rotundato, lateribus versus basin angustatis ; ab- 

 domine obsolete punctato, segmentis basalibus ad basin 

 transversim depressis. Long. vix. 2 mm. 



This little species reminds one by its form of the 

 European Tachyusa sulcata, Ivies. (Genus Xenusa, 

 Rey), but it is not half the size of it. The antennte are 

 entirely yellow, rather short, the three basal joints about 

 equal inter se in length, joints 6 — 10 each about as long 

 as broad, 11th joint small. Palpi yellow; head trans- 

 verse, very finely punctured, obscurely depressed along 

 the middle, the hind margin nearly straight. Thorax 

 about as broad as the head, a good deal narrower than 

 the elytra, the front margin a good deal rounded, the 

 front angles completely rounded, the sides from the front 

 angles to the base a good deal narrowed, in front of the 

 base in the middle is a transverse impression ; the ])unc- 

 tuation, like that of the head, is excessively fine. Elytra 

 longer than the thorax, finely and closely punctured. 

 Hind body distinctly a little broader from the base to near 

 the extremity, the lateral margins coarse, it is very indis- 

 tinctly punctured, but the basal dorsal segments are rather 

 deeply depressed in front. The legs are yellow, the tarsi 

 quite short. 



I have not been able to count the joints of the tarsi 

 of this little insect ; allied maritime species are pretty 

 certainly widely distributed throughout the world. 



Tavo S])ecimens have been captured by Mr. Blackburn 

 on the muddy sand about high-water mark at Kahului 

 Bay, Island of Maui.
