Mr. G. Lewis on Erotylidgeyro/w Japan. 69 



before tlie scutellura and another behind the neck, infuscate ; 

 punctures of thorax finer on the disk than on the sides ; scutel- 

 lura black, with a very few minute punctures ; elytra punctate- 

 striate, interstices irregularly punctate, punctures most visible 

 between the suture and the first stria. 



Monsieur Hiller obtained this at Hagi, near Shimonoseki, 

 and I took six specimens from a fungus on Salix, at Nowata, 

 June 22, 1880. 



Trijplax devia. 



Oblongo-ovata, nigra ; thorace rufo, antice et postice rotunde nigro 

 maculato ; antennis tarsisque infuscatis. L. 3|-4 mill. 



Head red, with clypeus and spot before the neck (often 

 covered by thorax) infuscate; punctures rather large and 

 sometimes ocellate, surface very minutely strigose ; thorax 

 rather evenly punctate, but punctures largest at the sides ; 

 behind the neck and in front of the scutellum are two large 

 round black spots ; elytra punctate-striate, interstices irre- 

 gularly and finely punctate. Beneath, the prosternum is rugose 

 and punctate, black between the coxee, raised in the middle 

 and slightly acute in front, lines incurved anteriorly or bent, 

 being difficult to see owing to the rugosity of the surface; meso- 

 sternum with a variolous sculpture ; abdomen, segments very 

 minutely sculptured throughout, with fair-sized punctures 

 interspersed, and in the three median segments the punctures 

 are arranged in transverse bands. 



Abundant at Hitoyoshi, May 3, 1881. Taken also at 

 Nikko and Miyanoshita not uncommonly. 



Triplax ainonia. 

 Oblongo-ovata, subopaca, dense punctata ; thorace flavo, antice et 

 postice in medio infuscato ; antennis (clava excepta) pedibusque 

 flavis. L. 3-31 mill. 



Above a little opaque and densely punctate ; head and 

 elytra obscurely, not intensely, black ; the thorax is yellow, 

 with a transverse antescutellar spot fuscous^ and a similarly 

 coloured maculation behind the head, which is characteristic 

 because posteriorly much narrowed in the middle ; the scutel- 

 lum is blackish with seven or eight punctures ; the elytra are 

 punctate-striate, and all the interstices distinctly punctate, the 

 punctures composing the striee not varying much in size from 

 thoseof the interstices. Beneath, the prosternal process is a little 

 raised, but the striee do not go much beyond the coxee and 

 terminate gradually. On the pro- and mesosternum the 

 punctuation is rather large ; the metasternum is minutely 

 strigose (when seen under a high power) and sparsely punc- 

 tate ; the abdominal segments are also densely punctate .
