tures ; at first glance it resembles /.'. coiicolor, on a small scale, but the jaws are 

 very ditiferent. The distance between the eyes of the male is almost equal to the 

 length of the three basal joints of antennae, in the female it is about one-third 

 more : on most of the specimens the hind >uture of the clypeus f ri im some direc- 

 tions appears t(.) be marked by a narrow shining line, but it is inconspicuous, or 

 invisible, from most directions. 



DITROPIDUS TRIANGULIFER sp, nov. 



d Black ; clypeus, labruni, a triangular space extendmg to between eyes, 

 and basal half of antennae flavous. Jriead, under-surface, and legs with sparse 

 pubescence. 



Head with dense, but partiallv concealed punctures, more distinct on clypeus 

 than elsewhere: median line feeble. Eyes widely separated. Prutliuni.v about twic- 

 as wide as the median length ; with small, sharply defined and rather dense punc- 

 tures, no larger on sides than in middle. Lil\tra rather short, distinctly narrowed 

 to apex ; with rows of large punctures, on the sides set in deep striae ; interstices 

 with sparse and scarcely visible punctures. Front legs slightly longer than hind 

 ones. Length, 2 75 mm.

Structurally and in general appearance close to D. viriditinctiis, but pro- 

 thorax with more distinct punctures, colour of head dilTerent and legs darker, 

 the legs are certainly not black, but they are too obscure to be regarded as more 

 than slightly diluted with red. the dilated sublaterobasal portion of each el^-tron is 

 of much the same colour. 



DITROPIDUS PUNCTIVARIUS sp. nov. 



d Black, upper-surface usually with a bluish or purplish gloss, labrum and 

 part of antennae red. Under-surfacc antl legs with very sparse pubescence. 



Head rather more convex than usual ; with sharply defined punctures, sparser 

 between eyes than elsewhere ; median line rather feeble. Eyes widelv separated. 

 Prothura.v not twice as wide as the median length, sides stronglv rounded; with 

 fairly dense and rather small [)unctures. no larger towards sides than in middle. 

 Elvira, for the genus, moderately long, sides slightly narrowed posteriorly ; with 

 rows of fairly large punctures, on the sides set in deep striae: inter.stices with very 

 minute punctures. Front legs scarcely longer than hind ones. Lengtli ( d 9 )• 

 3-4 mm.
