amber with four black fascia on disc and another pair near middle of sides almost 

 attaining the lateral margins, the anterior discal fascia do not attain the anterior 

 margin and are bluntly oval, the posterior pair are convergent posteriorly and are 

 produced to attain the posterior margin. Elytra amber colored with black areas 

 disposed as follows : humeral angles and scutellum and its cavity forming an irregu- 

 lar transverse band across the base; elongate area on each side margin near middle 

 with a sinuate band connecting them with the median vitta which extends backward 

 from the scutellum; posterior third except for two lateral rounded spots. Pro- 

 sternum and flanks amber, prosternal sutures black, remainder of ventron dark 

 brown, legs except coxae yellow. Front convex, anterior margin broadly rounded, 

 moderately punctate. Antennae with joints two and three subequal, together 

 equal to four. Pronotum not tuberculate at base, moderately evenly sparsely 

 punctate; posterior angles unicarinate, carina distinct to apex of posterior angles 

 where it joins the lateral margin. Elytra not spinose at tip. Prosternum finely 

 punctate, flanks coarsely punctate. Last abdominal segment similar in punctua- 

 tion to preceding segments. Tarsal joint four (PI. V, Fig. 3b) with a moderately 

 long slender lobe, not visible from above. 



Length, 5 mm. 



Type locality: Rio Madeira, Brazil. 



Type: No. 9046 Mus. Comp. Zool. Harvard University. 



Type collected by W. M. Mann and F. Baker. 



This species which I have named in honor of Dr. Baker is near 

 Monocrepidhis jpictus Cand. but is easily distinguished from this 

 species by the absence of the basal pronotal tubercle.

A PSYLLID GALL ON JUNCUS (LIVIA MACULIPENNIS 



FITCH).! 



By Edith M. Patch. 



Since 1857 when Fitch described this beautiful little insect, 

 nothing more definite in regard to its habits has been recorded than 

 that it is found in swampy places. Thomas in 1879 said that it was 

 "found on the sweet-flag," but there is nothing in his account 

 which would indicate that it fed upon that plant.
