lines are interrupted beyond the middle (exce^Dt the one next the suture), and where 

 they reappear beyond the interruption, are more irregular and mixed together, and 

 do not extend quite to the apex. The male has the front and middle tarsi a little 

 incrassate ; the apical ventral segment is abbreviate, and its hind margin nearly 

 straight, being scarcely produced in the middle and not at all at the sides. In the 

 female it is a good deal longer in the middle than it is at the sides, so as to form a 

 sort of indistinct middle lobe, but the lateral parts are not at all produced.

This species i.s very similar to Laccophilus grammicus, but is smaller and the 

 dark marks on the thoi-ax and elytra have a greater extension. The male is 

 unknown to me ; the female has the apical venti-al segment elongate in the middle, 

 but not forming a lobe, the sides forming very nearly a sioaple curve.

148. Laccophilus lateralis, n. sp. — Ovalis, sat convexus, minus nitidus, rufo-testa- 

 ceus, prothorace anterius et posterius infuscato, elytris nigro-suffusis, lateribus 

 signaturisque paululum conspicuis testaccis ; abdomine pectoreque nio-ro-suffusis.. 

 Long. 4, lat. 21 m.m. 



In this species the dark marks of the elytra are confluent so as to render the wing: 

 cases nearly entirely dark except at the sides ; in some specimens there are traces 

 of longitudinal pale marks. The male has the front and middle tarsi much 

 incrassate, and the apical ventral segment truncate but distinctly sinuate on each 

 side, the lateral angles projecting almost farther backwards than the middle part;, 

 in the female the hind margin of the last ventral segment forms a slender, but 

 rather elongate lobe in tlie middle, and the lateral angles are about similar to those 

 of the male.
