PROSTOMIS SCHLEGELII. 101 



striate , the interstices not very broad and impunctate , the 

 striae disappearing posteriorly leaving the apex smooth. 

 Under side coloured as above, except the jugular processes , 

 the mouth-parts etc. which are almost piceous , and the middle 

 of the sternum which is rather paler reddish brown; pro- 

 sternum finely and not very closely punctured ; meso- and 

 metasternum more distinctly and closely punctured espe- 

 cially near the sides; abdominal segments rather more 

 closely punctured. Legs reddish brown, the knees and 

 outer margins of the tibias darker , tarsi pale testaceous. — 

 Length 10 — 12 mm. 



Hab. Ceylon (Lewis , Braine etc.). 



The males may be known by the larger mandibles and 

 greater development of the lateral projection. 



This species has the head and prothorax proportionately 

 broader than any other with which I am acquainted ; it 

 is closely allied to Prostomis pacijicus Fairm. from Viti 

 (Ann. Soc. Ent. Fr. (6) I. p. 256), but differs not only 

 in the above particulars but also in having the mandibles 

 coriaceous and the head more strongly punctured behind 

 the eyes. I may here remark that P. pacijicus and P. 

 Schlegelii both differ from P. Atkinsonii Waterh. (Ent. Mo. 

 Mag. XIV. p. 26), described from Tasmania, in having 

 more convex mandibles and larger and more prominent 

 eyes. P. morsitans Pasc. from Darjeeling may readily 

 be distinguished from all the other species of the genus 

 by having the jugular processes very approximate at the 

 apex and one process decidedly longer than the other. 



Mr. George Lewis during his recent visit to Ceylon ob- 

 tained numerous specimens of F. Schlegelii and of its larva. 

 He informs me that they were found in clusters under 

 loose bark. The larva is so similar to that of the Euro- 

 pean P. mandibularis Fabr. described by Erichson (Archiv 

 fur Naturgesch. 1847. I. p. 285) and Curtis (Trans. Ent. Soc. 

 Lond. 1854. p. 37 ; pi. V. figs. 23—32) that it will not 

 be necessary to give a detailed description of it. The 

 average length of the specimens before me is 12'/2 mm.;
