as the median length, all angles rather strongly armed ; with 

 very feeble scattered punctures, but with some very con- 

 spicuous about the base and sides, and forming a short irregular 

 oblique row near each front angle. Flanks of prosternnrn 

 with distinct striae from base to apex. Femora minutely 

 dentate ; claws bifid. Length, 3-4 mm.

The general appearance is very suggestive of Arsipoda of 

 the Ilalticldes. The large punctures on the prothorax forming 

 an irregular, transverse row at the base, a few at the sides, and 

 a few forming a short, oblique line inwards from each of the 

 front angles, together with the conspicuously striated flanks of 

 prosternum are alike on the forty-three specimens before me, 

 so that, despite the great variations in colour, I believe them 

 to belong to but one species. It is difficult to be sure which 

 should be regarded as the typical form, but as there are nine- 

 teen almost similarly coloured specimens, one of these has been 

 regarded as the type; it belongs to the first form. The various 

 forms are as follow : — 



1. Of a dingy reddish-castaneous, some parts slightly paler 

 than others: apical half of antennae w^ith joints more or less 

 infuscated (nineteen specimens). 



2. Head and prothorax of a deeper red, the latter with an 

 infuscate spot in middle, each elytron with an infuscate spot 

 in the middle, at about the basal two-fifths ; legs partly black 

 (two specimens). 



3. Of a rather dark-red, elytra paler posteriorly, and each 

 with a conspicuous black vitta extending from the inter- 

 humeral depression (w^here it is narrowest) to slightly beyond 

 the middle (four specimens ; but one with markings so pale that 

 it should, perhaps, be regarded as belonging to Form 1). 



4. Under-surface more or less deeply infuscated, prothorax 

 and legs as on Form 2 ; elytra as on Form 3 (four specimens) . 



5. Deep-red; apical half of elytra black (the two colours 

 sharply defined, but the junction uneven), under-surface 

 mostly black, but outer half of each flank of prosternum con- 

 spicuously reddish, legs mostly black, antennae entirely pale, 

 except tip of eleventh joint (one specimen). 



6. Black, head and prothorax deep red; scutellum, parts 

 of base of elytra (on one specimen base of epipleurae as well), 

 parts of meso- and metasternum, of abdomen and of legs, more 

 or less obscurely reddish ; palpi and basal third of antennae 

 flavous, the rest black (six specimens).
